# ShareFile Class

The ShareFile class makes it easy to upload, download, and manage files, folders, and share links within ShareFile.

## Syntax

```text
ShareFile
```

## Remarks

The ShareFile class provides a simple interface for working with ShareFile. Capabilities include uploading and downloading files, strong encryption support, creating folders, moving and copying items, creating request and send links, and more.

## Authentication

 This class requires authentication via OAuth 2.0. First, perform OAuth authentication using the [OAuth](#oauth-property-sharefile-class) property to set the appropriate fields for the chosen [ClientProfile](#OAuthSettings_f_ClientProfile) and [GrantType](#OAuthSettings_f_GrantType).

The class has the following default:

|  |  |
| --- | --- |
| Authorization Server URL | "https://secure.sharefile.com/oauth/authorize" |

 For the [ServerTokenURL](#OAuthSettings_f_ServerTokenURL), the URL needs to contain the account subdomain of the account that authenticated. For example:

|  |  |
| --- | --- |
| Token Server URL | "https://{ACCOUNT}.sharefile.com/oauth/token" |

 Below is a brief description of the different [ClientProfile](#OAuthSettings_f_ClientProfile) and [GrantType](#OAuthSettings_f_GrantType) values that are supported by this class. For a more in-depth description of what needs to be set, refer to the service documentation.

### Application Profile

This profile encompasses the most basic grant types that OAuth supports. When this profile is set, all the requests and response handling is done by the class. Depending on the grant type, this may involve launching a browser so a user can login to authenticate with a authorization server. It may also involve starting an embedded web server to receive a response from a redirect.

To start the authentication and authorization process, the [Authorize](#authorize-method-sharefile-class) method should be called. If the authorization and authentication was successful, then the [AccessToken](#OAuthSettings_f_AccessToken) field will be populated. Additionally, if a *refresh token* was provided the [RefreshToken](#OAuthSettings_f_RefreshToken) field will be populated as well. These values of the fields are for informational purposes. The class will also cache these tokens along with when the [AccessToken](#OAuthSettings_f_AccessToken) will be expired. When a method that makes requests to the service provider is called or the [Authorize](#authorize-method-sharefile-class) method is called the class will automatically check to see if the *access token* is expired. If it is, it will then automatically try to get a new [AccessToken](#OAuthSettings_f_AccessToken). If the [Authorize](#authorize-method-sharefile-class) method was not used and user interaction would be required, the class will throw an error which can be caught. When user interaction is needed depends on what grant type is set in the [GrantType](#OAuthSettings_f_GrantType) field. To force the component to only check the *access token* when the [Authorize](#authorize-method-sharefile-class) method is called, the [OAuthAutomaticRefresh](#OAuthAutomaticRefresh) configuration setting can be set to false.

A brief description of the supported values for the [GrantType](#OAuthSettings_f_GrantType) field are below. For more information, see the service documentation.

**Authorization Code**

When using the *Authorization Code* grant type, the class will use an *authorization code* to get an *access token*. For this [GrantType](#OAuthSettings_f_GrantType) the class expects a [ClientId](#OAuthSettings_f_ClientId), [ClientSecret](#OAuthSettings_f_ClientSecret), [ServerAuthURL](#OAuthSettings_f_ServerAuthURL), and [ServerTokenURL](#OAuthSettings_f_ServerTokenURL) to be set. When the [Authorize](#authorize-method-sharefile-class) method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the class will parse the *authorization code*, setting the [AuthorizationCode](#OAuthSettings_f_AuthorizationCode) field, from the redirect. Immediately, the class will make a request to the token server to exchange the *authorization code* for an *access token*. The token server will return an *access token* and possibly a *refresh token*. If the [RefreshToken](#OAuthSettings_f_RefreshToken) field is set, or a *refresh token* is cached, then the class will not launch the browser and use the *refresh token* in its request to the token server instead of an *authorization code*.

**Implicit**

Note: This grant type is considered insecure and should only be used when necessary.

When using the *Implicit* grant type, the class will request the authorization server to get an *access token*. For this [GrantType](#OAuthSettings_f_GrantType) the class expects a [ClientId](#OAuthSettings_f_ClientId), [ClientSecret](#OAuthSettings_f_ClientSecret), and [ServerAuthURL](#OAuthSettings_f_ServerAuthURL) to be set. When the [Authorize](#authorize-method-sharefile-class) method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the class will parse the *access token* from the redirect.

A disadvantage of the grant type is that can not use a *refresh token* to silently get a new *access token*. Most service providers offer a way to silently get a new *access token*. See the service documentation for specifics. This means the class will not be able to automatically get a fresh token once it expires.

**Password**

Note: This grant type is considered insecure and should only be used when necessary.

When using the *Resource Owner Password Credentials* grant type, the class will authenticate as the resource owner. This allows for the class to avoid user interaction. This grant type often has specific limitations put on it by the service provider. See the service documentation for more details.

For this [GrantType](#OAuthSettings_f_GrantType) the class requires [OAuthPasswordGrantUsername](#OAuthPasswordGrantUsername), [ClientSecret](#OAuthSettings_f_ClientSecret), and [ServerTokenURL](#OAuthSettings_f_ServerTokenURL) to be set. The [ClientSecret](#OAuthSettings_f_ClientSecret) should be set to the password of the account instead of a typical secret. In some cases, the [ClientId](#OAuthSettings_f_ClientId) also needs to be set. When the [Authorize](#authorize-method-sharefile-class) method is called, the component will make a request to the token server for an *access token* using the username and password. The token server will return an *access token* if the authentication was successful. When this *access token* is expired, the component will automatically (see above for detailed description) make a new request to get a fresh one.

### Web Profile

 This profile is similar to setting the class to the Application profile and Authorization Code grant type except the class will not launch the browser. It is typically used in situations where there is a back-end that is supporting some front end. This profile expects that [ClientId](#OAuthSettings_f_ClientId), [ClientSecret](#OAuthSettings_f_ClientSecret), [ServerAuthURL](#OAuthSettings_f_ServerAuthURL), [ServerTokenURL](#OAuthSettings_f_ServerTokenURL), and the [ReturnURL](#OAuthSettings_f_ReturnURL) fields to be set. Before calling the [Authorize](#authorize-method-sharefile-class) method, the [WebAuthURL](#OAuthSettings_f_WebAuthURL) field should be queried to get a URL. This URL should be used to redirect the user to the authorization page for the service provider. The *redirect_uri* parameter of this URL is mapped to the [ReturnURL](#OAuthSettings_f_ReturnURL) field. The [ReturnURL](#OAuthSettings_f_ReturnURL) field should be set to some web server that will parse the *authorization code* out of the query parameter from the redirect. Once the *authorization code* is parsed, it should be passed back to the server where it is then set to the [AuthorizationCode](#OAuthSettings_f_AuthorizationCode) field. Once that is set, the [Authorize](#authorize-method-sharefile-class) method can be called to exchange the *authorization code* for an *access token* and *refresh token* if provided. The class will then cache these values like normal and use them to make requests. If the [RefreshToken](#OAuthSettings_f_RefreshToken) field is set, or a *refresh token* is cached, then the [Authorize](#authorize-method-sharefile-class) method can immediately be called to make a request to the token server to get a new *access token*.

### External OAuth Support

 For complex profiles or grant types, or for more control of the flow, it is possible to perform OAuth authentication using a separate OAuth client. Once complete you should have an authorization string which looks like:

```text
Bearer ACCESS_TOKEN_VALUE
```

Assign this value to the [Authorization](#authorization-property-sharefile-class) property before attempting any operations. Setting the [Authorization](#authorization-property-sharefile-class) property will cause the class to ignore the values set in the [OAuth](#oauth-property-sharefile-class) property.

Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.

## Referencing and Creating Items, Links, Permissions, and Users

ShareFile typically uses specified ids to reference its objects. When an object is created, through methods such as [CreateClient](#createclient-method-sharefile-class) or [CreateFolder](#createfolder-method-sharefile-class) or uploaded with the [UploadFile](#uploadfile-method-sharefile-class) method; the class will return with the objects ShareFile Id in the form of a string. In certain cases, a path (/parentFolder/ChildFolder) can be used to reference an item.

When a link is created using methods like [CreateAndEmailLink](#createandemaillink-method-sharefile-class) , [CreateAndEmailRequestLink](#createandemailrequestlink-method-sharefile-class), [CreateLink](#createlink-method-sharefile-class), or [CreateRequestLink](#createrequestlink-method-sharefile-class) then their URL is returned rather than their ShareFile id. To get the newly created id, the class also clears and populates the [Links](#links-property-sharefile-class) collection with the new link. When creating a link, you can use the [CreateLinkOptions](#createlinkoptions-property-sharefile-class) property to set certain options for the link.

When a permission is created using the [CreatePermission](#createpermission-method-sharefile-class) method, the class will not return anything as ShareFile uses a combination of a UserId and the ItemId of a folder to reference permissions. When creating a permission, you can use the [CreatePermissionOptions](#createpermissionoptions-property-sharefile-class) property to set certain options for the permission.

## Listing and Getting Items, Links, Permissions, and Users

When listing out the Links and Users currently available to the authenticated user you will use the corresponding [ListLinks](#listlinks-method-sharefile-class) and [ListUsers](#listusers-method-sharefile-class) methods. Both of these methods take no parameters and will populates their corresponding collection. For links the collection is the [Links](#links-property-sharefile-class) collection and for users it is the [Users](#users-property-sharefile-class) collection.

When listing the Items within a Folder or Permissions, the corresponding methods will take a folders ItemId. [ListItems](#listitems-method-sharefile-class) will list the items in the folder to the [Items](#items-property-sharefile-class) collection. The method will not recursively list out items found in child folders. The [ListPermissions](#listpermissions-method-sharefile-class) method will list all the permissions for the specified folder to the [Permissions](#permissions-property-sharefile-class) collection.

The class can also list out the items associated with a specified link. The [ListLinkItems](#listlinkitems-method-sharefile-class) method will take a LinkId and populate [Items](#items-property-sharefile-class) collection.

The class also offers the ability to get the specific information about a certain item, link, permission, or user. [GetItemInfo](#getiteminfo-method-sharefile-class), [GetLinkInfo](#getlinkinfo-method-sharefile-class) and [GetUserInfo](#getuserinfo-method-sharefile-class) each take a corresponding id. For permissions, [GetPermissionInfo](#getpermissioninfo-method-sharefile-class) will take a FolderId and UserId rather than a specific id. Once called, they each clear and populate the corresponding collection.

For all list* and get* methods, there is a corresponding event that will fire for each item in the list. The [ItemList](#itemlist-event-sharefile-class) event will fire when the [ListItems](#listitems-method-sharefile-class), [ListLinkItems](#listlinkitems-method-sharefile-class), or [GetItemInfo](#getiteminfo-method-sharefile-class) methods are called; the [LinkList](#linklist-event-sharefile-class) event will fire when the [ListLinks](#listlinks-method-sharefile-class) or [GetLinkInfo](#getlinkinfo-method-sharefile-class) methods are called; the [PermissionList](#permissionlist-event-sharefile-class) event will fire when the [ListPermissions](#listpermissions-method-sharefile-class) or [GetPermissionInfo](#getpermissioninfo-method-sharefile-class) methods are called; and the [UserList](#userlist-event-sharefile-class) event will fire when the [ListUsers](#listusers-method-sharefile-class) or [GetUserInfo](#getuserinfo-method-sharefile-class) methods are called.

## Downloading Files

The [DownloadFile](#downloadfile-method-sharefile-class) method downloads file or folder items.

If a stream has been specified using [SetDownloadStream](#setdownloadstream-method-sharefile-class), the file data will be sent through it. If a stream is not specified, and [LocalFile](#localfile-property-sharefile-class) is set, the file will be saved to the specified location; otherwise, the file data will be held by [ItemData](#itemdata-property-sharefile-class).

To download and decrypt an encrypted file, set [EncryptionAlgorithm](#encryptionalgorithm-property-sharefile-class) and [EncryptionPassword](#encryptionpassword-property-sharefile-class) before calling this method.

### Download Notes

**Simple Download**

A simple download is consistent with setting the [LocalFile](#localfile-property-sharefile-class) to the destination of the file when it is downloaded and then calling the method with the item's id. For example:

```text
shareFile.LocalFile = "../MyFile.zip";
shareFile.DownloadFile(shareFile.Items[0].Id);
```

**Streaming Download**

To download to a stream, first call the [SetDownloadStream](#setdownloadstream-method-sharefile-class) method and then call the [DownloadFile](#downloadfile-method-sharefile-class) method. For example:

```text
shareFile.LocalFile = "";
using (FileStream fs = new FileStream("../../temp/temp_data1.zip", FileMode.OpenOrCreate)) {
	shareFile.SetDownloadStream(fs);
	shareFile.DownloadFile(id);
}
```

## Uploading Files

The [UploadFile](#uploadfile-method-sharefile-class) method uploads new file items.

If [SetUploadStream](#setuploadstream-method-sharefile-class) has been used to set an upload stream, it will take priority as the file data source. If [LocalFile](#localfile-property-sharefile-class) is set the file will be uploaded from the specified path. If [LocalFile](#localfile-property-sharefile-class) is not set the data in [ItemData](#itemdata-property-sharefile-class) will be used.

To encrypt the file before uploading it, set [EncryptionAlgorithm](#encryptionalgorithm-property-sharefile-class) and [EncryptionPassword](#encryptionpassword-property-sharefile-class).

### Upload Notes

ShareFile offers two ways to upload a file. For smaller files a simple upload option is provided to upload data in one request. This is the default option. For larger files, uploads can be fragmented into multiple pieces, allowing resuming of uploads that may be interrupted.

**Simple**

By default the class uses the simple upload mechanism.

```text
ShareFile.LocalFile = "../MyFile.zip";
ShareFile.UploadFile("/MyFile.zip");
```

**Resumable**

To enable resumable uploads set [UseResumableUpload](#useresumableupload-property-sharefile-class) to *true*. This is recommended for large files. The class will automatically fragment the specified file into smaller pieces and upload each individually.

When [UseResumableUpload](#useresumableupload-property-sharefile-class) is set to *true* and [UploadFile](#uploadfile-method-sharefile-class) is called, a resumable upload session is started by the class. Once called and the class fragments the file, the [ResumeURL](#resumeurl-property-sharefile-class) property is populated. This URL needs to be set so that the class can resume the upload if the upload is interrupted.

During a resumable upload, the [FragmentComplete](#fragmentcomplete-event-sharefile-class) event fires after each fragment is uploaded to indicate overall progress. The class also updates [StartByte](#startbyte-property-sharefile-class) as necessary to indicate the current offset in the file.

If the upload is interrupted for any reason, resuming it is easy. First, verify that [ResumeURL](#resumeurl-property-sharefile-class) and [StartByte](#startbyte-property-sharefile-class) are populated (if the same instance of the class is used, they should already be populated, and no special action should be needed). If uploading from a stream, be sure to reset its position to where it was the first time the upload was started (typically the beginning). Then call [UploadFile](#uploadfile-method-sharefile-class) again to resume the upload at the specified [StartByte](#startbyte-property-sharefile-class) offset.

Note that if the upload is not resumed after some time the upload session will expire.

```text
shareFile.UseResumableUpload = true;
shareFile.LocalFile = "../MyFile.zip";
shareFile.UploadFile("MyFile.zip");

// The transfer is interrupted and UploadFile() above fails. Later, resume the download.
// Using the same instance StartByte and ResumeURL are already populated from the previous
// upload attempt.
shareFile.UploadFile("MyFile.zip");
```

```text
MemoryStream uploadStream = new MemoryStream(File.ReadAllBytes("../MyFile.zip"));
shareFile.UseResumableUpload = true;
shareFile.SetUploadStream(uploadStream);
shareFile.UploadFile("MyFile.zip");

// The transfer is interrupted and UploadFile() above fails. Later, resume the download.
// Using the same instance StartByte and ResumeURL are already populated from the previous
// upload attempt.
// You MUST reset the stream's position to where it was when you first started the upload!
uploadStream.Position = 0;
shareFile.UploadFile("MyFile.zip");
```

## Additional Functionality

The ShareFile class offers advanced functionality beyond simple uploads and downloads. For instance:

- Encrypt and decrypt files using the [EncryptionAlgorithm](#encryptionalgorithm-property-sharefile-class) and [EncryptionPassword](#encryptionpassword-property-sharefile-class) properties.
- Basic file and folder manipulation and organization using methods such as [CopyItem](#copyitem-method-sharefile-class) and [MoveItem](#moveitem-method-sharefile-class).
- And more!

# SSLProvider Property ([ShareFile](#sharefile-class) Class)

The Secure Sockets Layer/Transport Layer Security (SSL/TLS) implementation to use.

## Syntax

```text
ANSI (Cross Platform)
int GetSSLProvider();int SetSSLProvider(int iSSLProvider);

Unicode (Windows)
INT GetSSLProvider();INT SetSSLProvider(INT iSSLProvider);
```

## Possible Values

```text
SSLP_AUTOMATIC(0), SSLP_PLATFORM(1), SSLP_INTERNAL(2)
```

## Default Value

0

## Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of *0* (Automatic) is recommended and should not be changed. When set to *0* (Automatic), the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are as follows:

|  |  |
| --- | --- |
| 0 (sslpAutomatic - default) | Automatically selects the appropriate implementation. |
| 1 (sslpPlatform) | Uses the platform/system implementation. |
| 2 (sslpInternal) | Uses the internal implementation. |

 **Additional Notes**

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected, on Windows, the class will use the platform implementation. On Linux/macOS, the class will use the internal implementation. When TLS 1.3 is enabled via [SSLEnabledProtocols](#SSLEnabledProtocols), the class will always try and use the platform implementation. If the platform TLS 1.3 implementation is not available, the internal implementation will be used.

## Data Type

Integer

# SSLServerCert Property ([ShareFile](#sharefile-class) Class)

The server certificate for the last established connection.

## Syntax

```text
CloudStorageCertificate* GetSSLServerCert();
```

## Remarks

This property contains the server certificate for the last established connection.

SSLServerCert is reset every time a new connection is attempted.

This property is read-only.

## Data Type

[CloudStorageCertificate](#certificate-type)

# StartByte Property ([ShareFile](#sharefile-class) Class)

The byte offset from which to start the upload or download.

## Syntax

```text
ANSI (Cross Platform)
int64 GetStartByte();int SetStartByte(int64 lStartByte);

Unicode (Windows)
LONG64 GetStartByte();INT SetStartByte(LONG64 lStartByte);
```

## Default Value

0

## Remarks

This property may be set to resume an upload or download; it specifies the offset in the file (or stream, when uploading) from which to resume. See [UploadFile](#uploadfile-method-sharefile-class) and [DownloadFile](#downloadfile-method-sharefile-class) for details about resuming uploads and downloads.

When uploading from a stream, the class will *always* seek forward in the stream if the value of StartByte is greater than 0 when [UploadFile](#uploadfile-method-sharefile-class) is called. Keep this in mind when resuming interrupted uploads.

This property is not available at design time.

## Data Type

Long64

# Timeout Property ([ShareFile](#sharefile-class) Class)

The timeout for the class.

## Syntax

```text
ANSI (Cross Platform)
int GetTimeout();int SetTimeout(int iTimeout);

Unicode (Windows)
INT GetTimeout();INT SetTimeout(INT iTimeout);
```

## Default Value

60

## Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If Timeout expires, and the operation is not yet complete, the class fails with an error.

NOTE: By default, all timeouts are *inactivity timeouts*, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

## Data Type

Integer

# UseResumableUpload Property ([ShareFile](#sharefile-class) Class)

Whether to use resumable uploads.

## Syntax

```text
ANSI (Cross Platform)
int GetUseResumableUpload();int SetUseResumableUpload(int bUseResumableUpload);

Unicode (Windows)
BOOL GetUseResumableUpload();INT SetUseResumableUpload(BOOL bUseResumableUpload);
```

## Default Value

FALSE

## Remarks

This property controls whether simple or resumable uploads are used when [UploadFile](#uploadfile-method-sharefile-class) is called. The default value is *false* (simple uploads are used).

Refer to [UploadFile](#uploadfile-method-sharefile-class) for more information.

This property is not available at design time.

## Data Type

Boolean

# Users Property ([ShareFile](#sharefile-class) Class)

## Syntax

```text
ANSI (Cross Platform)
int AddQueryParam(const char* lpszName, const char* lpszValue);

Unicode (Windows)
INT AddQueryParam(LPCWSTR lpszName, LPCWSTR lpszValue);
```

## Remarks

This method is used to add a query parameter to the [QueryParams](#queryparams-property-sharefile-class) collection. *Name* specifies the name of the parameter, and *Value* specifies the value of the parameter.

All specified *Value*s will be URL encoded by the class automatically. Consult the service documentation for details on the available parameters.

## Error Handling (C++)

This method returns a result code; *0* indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the *GetLastError()* method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the *GetLastErrorCode()* method after it returns.)

# Authorize Method ([ShareFile](#sharefile-class) Class)

Get the authorization string required to access the protected resource.

## Syntax

```text
ANSI (Cross Platform)
int Authorize();

Unicode (Windows)
INT Authorize();
```

## Remarks

This method is used to get an access token that is required to access the protected resource. The method will act differently based on what is set in the [ClientProfile](#OAuthSettings_f_ClientProfile) field and the [GrantType](#OAuthSettings_f_GrantType) field. This method is **not** to be used in conjunction with the [Authorization](#authorization-property-sharefile-class) property. It should instead be used when setting the [OAuth](#oauth-property-sharefile-class) property.

For more information, see the introduction section.

## Error Handling (C++)

This method returns a result code; *0* indicates success, while a non-zero error code indicates that this method encountered an error during its execution.

# Config Method ([ShareFile](#sharefile-class) Class)

Sets or retrieves a configuration setting.

## Syntax

```text
ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);
```

## Remarks

Config is a generic method available in every class. It is used to set and retrieve [configuration settings](#config-settings-sharefile-class) for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these *internal properties* is provided through the Config method.

To set a configuration setting named *PROPERTY*, you must call *Config("PROPERTY=VALUE")*, where *VALUE* is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a [configuration setting](#config-settings-sharefile-class), you must call *Config("PROPERTY")*. The value will be returned as a string.

## Error Handling (C++)

This method returns a String value; after it returns, call the *GetLastErrorCode()* method to obtain its result code; *0* indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the *GetLastError()* method can be called to retrieve the associated error message.

# CopyItem Method ([ShareFile](#sharefile-class) Class)

If the [Overwrite](#overwrite-property-sharefile-class) property is set to true, then the class will overwrite a file if one is found at the location specified by the [LocalFile](#localfile-property-sharefile-class) property. If it is set to false, then the class will throw an error if it finds a collision.

If a stream has been specified using [SetDownloadStream](#setdownloadstream-method-sharefile-class), the file data will be sent through it. If a stream is not specified, and [LocalFile](#localfile-property-sharefile-class) is set, the file will be saved to the specified location; otherwise, the file data will be held by [ItemData](#itemdata-property-sharefile-class).

To download and decrypt an encrypted file, set [EncryptionAlgorithm](#encryptionalgorithm-property-sharefile-class) and [EncryptionPassword](#encryptionpassword-property-sharefile-class) before calling this method.

### Download Notes

**Simple Download**

A simple download is consistent with setting the [LocalFile](#localfile-property-sharefile-class) to the destination of the file when it is downloaded and then calling the method with the item's id. For example:

```text
shareFile.LocalFile = "../MyFile.zip";
shareFile.DownloadFile(shareFile.Items[0].Id);
```

**Streaming Download**

To download to a stream, first call the [SetDownloadStream](#setdownloadstream-method-sharefile-class) method and then call the DownloadFile method. For example:

```text
shareFile.LocalFile = "";
using (FileStream fs = new FileStream("../../temp/temp_data1.zip", FileMode.OpenOrCreate)) {
	shareFile.SetDownloadStream(fs);
	shareFile.DownloadFile(id);
}
```

## Error Handling (C++)

This method returns a result code; *0* indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the *GetLastError()* method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the *GetLastErrorCode()* method after it returns.)

# GetItemInfo Method ([ShareFile](#sharefile-class) Class)

## Remarks

Calling this method will fire the [ItemList](#itemlist-event-sharefile-class) event, and will populate the [Items](#items-property-sharefile-class) collection (clearing any previously-held items in the process)

*ItemId* is the id of the items that the class will get the information for. If the method is supplied a path (e.g. "/parentFolder/ChildFolder") then the class will use the path to get the item information.

**Passing an ID**

```text
string dirId = shareFile.CreateFolder("NewFolder", "home");
shareFile.GetItemInfo(dirId);
```

### Usage

 When this method is called, the class does the following:

1.  Builds a request URL, including query parameters, as follows:

  - The specified *RequestPath* is appended to the ShareFile API's stable endpoint, *https://[SUBDOMAIN].sf-api.com/sf/v3*.
  - All query parameters in the [QueryParams](#queryparams-property-sharefile-class) collection are added to the request URL.

2. Sends the request using the specified *HttpMethod*, the request URL build in step 1, the header information held by [Authorization](#Authorization) and [OtherHeaders](#OtherHeaders), and the given *RequestBody* (if non-empty).
3. Stores the response headers in the [ParsedHeaders](#parsedheaders-property-sharefile-class) collection, and the response body in the stream specified using [SetDownloadStream](#setdownloadstream-method-sharefile-class), or the specified [LocalFile](#localfile-property-sharefile-class) (using the same logic as [DownloadFile](#downloadfile-method-sharefile-class)).

If the response body is JSON data, the [XPath](#XPath), [XText](#XText), and other **X*** configuration settings can then be used to navigate and extract information from it.

## Error Handling (C++)

This method returns a result code; *0* indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the *GetLastError()* method can be called to retrieve the associated error message.

# UploadFile Method ([ShareFile](#sharefile-class) Class)

Will upload a file to a folder.

## Syntax

```text
ANSI (Cross Platform)
char* UploadFile(const char* lpszFileName, const char* lpszParentId);

Unicode (Windows)
LPWSTR UploadFile(LPCWSTR lpszFileName, LPCWSTR lpszParentId);
```

## Remarks

The method when called will upload a file specified in the [LocalFile](#localfile-property-sharefile-class) property. If [SetUploadStream](#setuploadstream-method-sharefile-class) has been used to set an upload stream, it will take priority as the file data source. If [LocalFile](#localfile-property-sharefile-class) has not been set or a stream has not been set using [SetUploadStream](#setuploadstream-method-sharefile-class) then the class will use the data found in the [ItemData](#itemdata-property-sharefile-class) property; The file will be uploaded to the folder specified by the *ParentId* parameter. The name of the file will be what is passed to the *FileName* parameter. Once it has completed uploading it will return the id of the uploaded file.

Note that the string *root* may be used as a *ParentId* to represent the root folder, and the string *home* may be used as a folder Id to represent the home folder for the current user. Other special id's include:

- *favorites*
- *allshared*

### Name Conflict Resolution

 The class will overwrite a file if a file is uploaded to the same folder with the same name.

If [SetUploadStream](#setuploadstream-method-sharefile-class) has been used to set an upload stream, it will take priority as the file data source. If [LocalFile](#localfile-property-sharefile-class) is set the file will be uploaded from the specified path. If [LocalFile](#localfile-property-sharefile-class) is not set the data in [ItemData](#itemdata-property-sharefile-class) will be used.

To encrypt the file before uploading it, set [EncryptionAlgorithm](#encryptionalgorithm-property-sharefile-class) and [EncryptionPassword](#encryptionpassword-property-sharefile-class).

### Upload Notes

ShareFile offers two ways to upload a file. For smaller files a simple upload option is provided to upload data in one request. This is the default option. For larger files, uploads can be fragmented into multiple pieces, allowing resuming of uploads that may be interrupted.

**Simple**

By default the class uses the simple upload mechanism.

```text
ShareFile.LocalFile = "../MyFile.zip";
ShareFile.UploadFile("/MyFile.zip");
```

**Resumable**

To enable resumable uploads set [UseResumableUpload](#useresumableupload-property-sharefile-class) to *true*. This is recommended for large files. The class will automatically fragment the specified file into smaller pieces and upload each individually.

When [UseResumableUpload](#useresumableupload-property-sharefile-class) is set to *true* and UploadFile is called, a resumable upload session is started by the class. Once called and the class fragments the file, the [ResumeURL](#resumeurl-property-sharefile-class) property is populated. This URL needs to be set so that the class can resume the upload if the upload is interrupted.

During a resumable upload, the [FragmentComplete](#fragmentcomplete-event-sharefile-class) event fires after each fragment is uploaded to indicate overall progress. The class also updates [StartByte](#startbyte-property-sharefile-class) as necessary to indicate the current offset in the file.

If the upload is interrupted for any reason, resuming it is easy. First, verify that [ResumeURL](#resumeurl-property-sharefile-class) and [StartByte](#startbyte-property-sharefile-class) are populated (if the same instance of the class is used, they should already be populated, and no special action should be needed). If uploading from a stream, be sure to reset its position to where it was the first time the upload was started (typically the beginning). Then call UploadFile again to resume the upload at the specified [StartByte](#startbyte-property-sharefile-class) offset.

Note that if the upload is not resumed after some time the upload session will expire.

```text
shareFile.UseResumableUpload = true;
shareFile.LocalFile = "../MyFile.zip";
shareFile.UploadFile("MyFile.zip");

// The transfer is interrupted and UploadFile() above fails. Later, resume the download.
// Using the same instance StartByte and ResumeURL are already populated from the previous
// upload attempt.
shareFile.UploadFile("MyFile.zip");
```

```text
MemoryStream uploadStream = new MemoryStream(File.ReadAllBytes("../MyFile.zip"));
shareFile.UseResumableUpload = true;
shareFile.SetUploadStream(uploadStream);
shareFile.UploadFile("MyFile.zip");

// The transfer is interrupted and UploadFile() above fails. Later, resume the download.
// Using the same instance StartByte and ResumeURL are already populated from the previous
// upload attempt.
// You MUST reset the stream's position to where it was when you first started the upload!
uploadStream.Position = 0;
shareFile.UploadFile("MyFile.zip");
```

## Error Handling (C++)

This method returns a String value; after it returns, call the *GetLastErrorCode()* method to obtain its result code; *0* indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the *GetLastError()* method can be called to retrieve the associated error message.

# EndTransfer Event ([ShareFile](#sharefile-class) Class)

Fired when a document finishes transferring.

## Syntax

```text
ANSI (Cross Platform)
virtual int FireEndTransfer(ShareFileEndTransferEventParams *e);
typedef struct {  int Direction;
  int reserved;
} ShareFileEndTransferEventParams;

Unicode (Windows)
virtual INT FireEndTransfer(ShareFileEndTransferEventParams *e);
typedef struct {  INT Direction;
  INT reserved;
} ShareFileEndTransferEventParams;
```

## Remarks

This event is fired first when the client finishes sending data to the server (in a *POST* or *PUT* request) and then when the document text finishes transferring from the server to the local host.

The *Direction* parameter shows whether the client (0) or the server (1) is sending the data.

# Error Event ([ShareFile](#sharefile-class) Class)

Fired when information is available about errors during data delivery.

## Syntax

```text
ANSI (Cross Platform)
virtual int FireError(ShareFileErrorEventParams *e);
typedef struct {  int ErrorCode;  const char *Description;
  int reserved;
} ShareFileErrorEventParams;

Unicode (Windows)
virtual INT FireError(ShareFileErrorEventParams *e);
typedef struct {  INT ErrorCode;  LPCWSTR Description;
  INT reserved;
} ShareFileErrorEventParams;
```

## Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

The *ErrorCode* parameter contains an error code, and the *Description* parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the [Error Codes](#trappable-errors-sharefile-class) section.

# FragmentComplete Event ([ShareFile](#sharefile-class) Class)

Fires after each fragment of a resumable upload is completed.

## Syntax

```text
ANSI (Cross Platform)

} ShareFileFragmentCompleteEventParams;
```

## Remarks

When [UseResumableUpload](#useresumableupload-property-sharefile-class) is *true* and [UploadFile](#uploadfile-method-sharefile-class) is called, this event will fire after each fragment is uploaded, providing an indication of overall upload progress.

*FragmentNumber* is the number of the current fragment that has completed. This value starts at *1*.

*FragmentCount* is the total number of fragments that will be uploaded.

*Interrupt* can be set to *true* to interrupt the upload. The upload may be resumed later.

# Header Event ([ShareFile](#sharefile-class) Class)

Fired every time a header line comes in.

## Syntax

```text
ANSI (Cross Platform)
virtual int FireHeader(ShareFileHeaderEventParams *e);
typedef struct {  const char *Field;  const char *Value;
  int reserved;
} ShareFileHeaderEventParams;

Unicode (Windows)
virtual INT FireHeader(ShareFileHeaderEventParams *e);
typedef struct {  LPCWSTR Field;  LPCWSTR Value;
  INT reserved;
} ShareFileHeaderEventParams;
```

## Remarks

The *Field* parameter contains the name of the HTTP header (which is the same as it is delivered). The *Value* parameter contains the header contents.

If the header line being retrieved is a continuation header line, then the *Field* parameter contains "" (empty string).

# ItemList Event ([ShareFile](#sharefile-class) Class)

This event fires once for each item returned when either ListItems , ListLinkItems or GetItemInfo is called.

## Syntax

```text
ANSI (Cross Platform)
virtual int FireItemList(ShareFileItemListEventParams *e);
typedef struct {  const char *Id;  const char *Name;  const char *Path;  const char *CreatorFirstName;  const char *CreatorLastName;  int ItemType;  const char *ParentId;  const char *Description;  const char *ExpirationDate;  const char *CreationDate;  int64 Size;

Unicode (Windows)
virtual INT FireLog(ShareFileLogEventParams *e);
typedef struct {  INT LogLevel;  LPCWSTR Message;  LPCWSTR LogType;
  INT reserved;
} ShareFileLogEventParams;
```

## Remarks

This event is fired once for each log message generated by the class. The verbosity is controlled by the [LogLevel](#LogLevel) setting.

*LogLevel* indicates the level of message. Possible values are as follows:

|  |  |
| --- | --- |
| 0 (None) | No events are logged. |
| 1 (Info - default) | Informational events are logged. |
| 2 (Verbose) | Detailed data are logged. |
| 3 (Debug) | Debug data are logged. |

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

*Message* is the log entry.

*LogType* identifies the type of log entry. Possible values are as follows:

- "Info"
- "RequestHeaders"
- "ResponseHeaders"
- "RequestBody"
- "ResponseBody"
- "ProxyRequest"
- "ProxyResponse"
- "FirewallRequest"
- "FirewallResponse"

# PermissionList Event ([ShareFile](#sharefile-class) Class)

This event fires once for each permission returned when ListPermissions or GetPermissionInfo is called.

## Syntax

```text
ANSI (Cross Platform)
virtual int FirePermissionList(ShareFilePermissionListEventParams *e);
typedef struct {  const char *FolderId;  const char *UserId;  int CanDelete;  int CanDownload;  int CanManagePermissions;  int CanUpload;  int CanView;  int IsOwner;  int NotifyOnDownload;  int NotifyOnUpload;
  int reserved;
} ShareFilePermissionListEventParams;

Unicode (Windows)
virtual INT FirePermissionList(ShareFilePermissionListEventParams *e);
typedef struct {  LPCWSTR FolderId;  LPCWSTR UserId;  BOOL CanDelete;  BOOL CanDownload;  BOOL CanManagePermissions;  BOOL CanUpload;  BOOL CanView;  BOOL IsOwner;  BOOL NotifyOnDownload;  BOOL NotifyOnUpload;
  INT reserved;
} ShareFilePermissionListEventParams;
```

## Remarks

This event fires once for each permission returned when [ListPermissions](#listpermissions-method-sharefile-class) or [GetPermissionInfo](#getpermissioninfo-method-sharefile-class) is called. The permissions cannot be modified from this event. The *FolderId* represents the item Id for the specific folder the permission is for. The *UserId* represents the Id for the user the permission is for.

# Progress Event ([ShareFile](#sharefile-class) Class)

Fires during an upload or download to indicate transfer progress.

## Syntax

```text
ANSI (Cross Platform)
virtual int FireProgress(ShareFileProgressEventParams *e);
typedef struct {  int Direction;  int64 BytesTransferred;  int64 TotalBytes;  int PercentDone;
  int reserved;
} ShareFileProgressEventParams;

Unicode (Windows)
virtual INT FireProgress(ShareFileProgressEventParams *e);
typedef struct {  INT Direction;  LONG64 BytesTransferred;  LONG64 TotalBytes;  INT PercentDone;
  INT reserved;
} ShareFileProgressEventParams;
```

## Remarks

This event fires during an upload or download to indicate the progress of the transfer of the entire request. By default, this event will fire each time *PercentDone* increases by one percent; the [ProgressStep](#ProgressStep) configuration setting can be used to alter this behavior.

*Direction* indicates whether the transfer is an upload (*0*) or a download (*1*).

*BytesTransferred* reflects the number of bytes that have been transferred so far, or *0* if the transfer is starting (however, see note below).

*TotalBytes* reflects the total number of bytes that are to be transferred, or *-1* if the total is unknown. This amount includes the size of everything in the request like HTTP headers.

*PercentDone* reflects the overall progress of the transfer, or *-1* if the progress cannot be calculated.

NOTE: By default, the class tracks transfer progress *absolutely*. If a transfer is interrupted and later resumed, the values reported by this event upon and after resumption will account for the data that was transferred *before* the interruption.

For example, if 10MB of data was successfully transferred before the interruption, then this event will fire with a *BytesTransferred* value of *10485760* (10MB) when the transfer is first resumed, and then continue to fire with successively greater values as usual.

This behavior can be changed by disabling the [ProgressAbsolute](#ProgressAbsolute) configuration setting, in which case the class will treat resumed transfers as "new" transfers. In this case, the *BytesTransferred* parameter will always be *0* the first time this event fires, regardless of whether the transfer is new or being resumed.

# SSLServerAuthentication Event ([ShareFile](#sharefile-class) Class)

Fired after the server presents its certificate to the client.

## Syntax

```text
ANSI (Cross Platform)
virtual int FireSSLServerAuthentication(ShareFileSSLServerAuthenticationEventParams *e);
typedef struct {  const char *CertEncoded;
  int lenCertEncoded;  const char *CertSubject;  const char *CertIssuer;  const char *Status;  int Accept;
  int reserved;
} ShareFileSSLServerAuthenticationEventParams;

Unicode (Windows)
virtual INT FireSSLServerAuthentication(ShareFileSSLServerAuthenticationEventParams *e);
typedef struct {  LPCSTR CertEncoded;
  INT lenCertEncoded;  LPCWSTR CertSubject;  LPCWSTR CertIssuer;  LPCWSTR Status;  BOOL Accept;
  INT reserved;
} ShareFileSSLServerAuthenticationEventParams;
```

## Remarks

During this event, the client can decide whether or not to continue with the connection process. The *Accept* parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

 When *Accept* is False, *Status* shows why the verification failed (otherwise, *Status* contains the string *OK*). If it is decided to continue, you can override and accept the certificate by setting the *Accept* parameter to True.

# SSLStatus Event ([ShareFile](#sharefile-class) Class)

Fired when secure connection progress messages are available.

## Syntax

```text
ANSI (Cross Platform)
virtual int FireSSLStatus(ShareFileSSLStatusEventParams *e);
typedef struct {  const char *Message;
  int reserved;
} ShareFileSSLStatusEventParams;

Unicode (Windows)
virtual INT FireSSLStatus(ShareFileSSLStatusEventParams *e);
typedef struct {  LPCWSTR Message;
  INT reserved;
} ShareFileSSLStatusEventParams;
```

## Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

# StartTransfer Event ([ShareFile](#sharefile-class) Class)

Fired when a document starts transferring (after the headers).

## Syntax

```text
ANSI (Cross Platform)
virtual int FireStartTransfer(ShareFileStartTransferEventParams *e);
typedef struct {  int Direction;
  int reserved;
} ShareFileStartTransferEventParams;

Unicode (Windows)
virtual INT FireStartTransfer(ShareFileStartTransferEventParams *e);
typedef struct {  INT Direction;
  INT reserved;
} ShareFileStartTransferEventParams;
```

## Remarks

This event is fired first when the client starts sending data to the server (in a *POST* or *PUT* request) and then when the document text starts transferring from the server to the local host.

The *Direction* parameter shows whether the client (0) or the server (1) is sending the data.

# Transfer Event ([ShareFile](#sharefile-class) Class)

Fired while a document transfers (delivers document).

## Syntax

```text
ANSI (Cross Platform)
virtual int FireTransfer(ShareFileTransferEventParams *e);
typedef struct {  int Direction;  int64 BytesTransferred;  int PercentDone;  const char *Text;
  int lenText;
  int reserved;
} ShareFileTransferEventParams;

Unicode (Windows)
virtual INT FireTransfer(ShareFileTransferEventParams *e);
typedef struct {  INT Direction;  LONG64 BytesTransferred;  INT PercentDone;  LPCSTR Text;
  INT lenText;
  INT reserved;
} ShareFileTransferEventParams;
```

## Remarks

The *Text* parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The *BytesTransferred* parameter contains the number of bytes transferred in this *Direction* since the beginning of the document text (excluding HTTP response headers).

The *Direction* parameter shows whether the client (0) or the server (1) is sending the data.

The *PercentDone* parameter shows the progress of the transfer in the corresponding direction. If *PercentDone* can not be calculated the value will be -1.

NOTE: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

# UserList Event ([ShareFile](#sharefile-class) Class)

This event fires once for each user returned when ListUsers or GetUserInfo is called.

## Syntax

```text
ANSI (Cross Platform)
virtual int FireUserList(ShareFileUserListEventParams *e);
typedef struct {  const char *Id;  const char *FirstName;  const char *LastName;  const char *Company;  const char *Email;  const char *CreationDate;
  int reserved;
} ShareFileUserListEventParams;

Unicode (Windows)
virtual INT FireUserList(ShareFileUserListEventParams *e);
typedef struct {  LPCWSTR Id;  LPCWSTR FirstName;  LPCWSTR LastName;  LPCWSTR Company;  LPCWSTR Email;  LPCWSTR CreationDate;
  INT reserved;
} ShareFileUserListEventParams;
```

## Remarks

This event fires once for each user returned when [ListUsers](#listusers-method-sharefile-class) or [GetUserInfo](#getuserinfo-method-sharefile-class) is called. The users cannot be modified from this event. If the user does not have a specified company that parameter will be left as an empty string ("").

[Store](#Certificate_f_Store) is used in conjunction with the [Subject](#Certificate_f_Subject) field to specify client certificates. If [Store](#Certificate_f_Store) has a value, and [Subject](#Certificate_f_Subject) or [Encoded](#Certificate_f_Encoded) is set, a search for a certificate is initiated. Please see the [Subject](#Certificate_f_Subject) field for details.

 Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

|  |  |
| --- | --- |
| MY | A certificate store holding personal certificates with their associated private keys. |
| CA | Certifying authority certificates. |
| ROOT | Root certificates. |

When the certificate store type is *cstPFXFile*, this property must be set to the name of the file. When the type is *cstPFXBlob*, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

 **StorePassword** *char**
*Default Value: ""*

If the type of certificate store requires a password, this field is used to specify the password needed to open the certificate store.

 **StoreType** *int*
*Default Value: 0*

The type of certificate store for this certificate.

 The class supports both public and private keys in a variety of formats. When the *cstAuto* value is used, the class will automatically determine the type. This field can take one of the following values:

```csharp
sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11,
                               @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll",
                               "123456", // PIN
                               "CN=cert_subject");
sftp.SSHUser = "test";
sftp.SSHLogon("myhost", 22);
```

```csharp
certmgr.CertStoreType = CertStoreTypes.cstPKCS11;
certmgr.OnCertList += (s, e) => {
  secKeyBlob = e.CertEncoded;
};
certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll";
certmgr.CertStorePassword = "123456"; // PIN
certmgr.ListStoreCertificates();

sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*");
sftp.SSHUser = "test";
sftp.SSHLogon("myhost", 22);
```

 **Subject** *char**
*Default Value: ""*

The subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the field is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=example@email.com". Common fields and their meanings are as follows:

| Field | Meaning |
| --- | --- |
| CN | Common Name. This is commonly a hostname like www.server.com. |

*Default Value: ""*

The certificate (PEM/Base64 encoded). This field is used to assign a specific certificate. The [Store](#Certificate_f_Store) and [Subject](#Certificate_f_Subject) fields also may be used to specify a certificate.

When [Encoded](#Certificate_f_Encoded) is set, a search is initiated in the current [Store](#Certificate_f_Store) for the private key of the certificate. If the key is found, [Subject](#Certificate_f_Subject) is updated to reflect the full subject of the selected certificate; otherwise, [Subject](#Certificate_f_Subject) is set to an empty string.

## Constructors

```text
Certificate()
```

 Creates a instance whose properties can be set.

```text
Certificate(const char* lpEncoded, int lenEncoded)
```

 Parses * Encoded * as an X.509 public key.

```text
Certificate(int iStoreType, const char* lpStore, int lenStore, const char* lpszStorePassword, const char* lpszSubject)
```

 * StoreType * identifies the type of certificate store to use. See for descriptions of the different certificate stores. * Store * is a byte array containing the certificate data. * StorePassword * is the password used to protect the store.

 After the store has been successfully opened, the component will attempt to find the certificate identified by * Subject * . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The * Subject * parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format.

# CloudStorageList Type

## Syntax

 *CloudStorageList<T>* (declared in *cloudstorage.h*)

## Remarks

 *CloudStorageList* is a generic class that is used to hold a collection of objects of type *T*, where *T* is one of the custom types supported by the ShareFile class.

```text
int GetCount() {}
```

```text
int SetCount(int count) {}
```

```text
T* Get(int index) {}
```

```text
T* Set(int index, T* value) {}
```

|  |  |
| --- | --- |
| Methods |  |
| GetCount | This method returns the current size of the collection. |
| SetCount | This method sets the size of the collection. This method returns 0 if setting the size was successful; or -1 if the collection is ReadOnly. When adding additional objects to a collection call this method to specify the new size. Increasing the size of the collection preserves existing objects in the collection. |
| Get | This method gets the item at the specified position. The index parameter specifies the index of the item in the collection. This method returns NULL if an invalid index is specified. |
| Set | This method sets the item at the specified position. The index parameter specifies the index of the item in the collection that is being set. This method returns -1 if an invalid index is specified. Note: Objects created using the new operator must be freed using the delete operator; they will not be automatically freed by the class. |

# CloudStorageStream Type

## Syntax

 *CloudStorageStream* (declared in *cloudstorage.h*)

## Remarks

 The ShareFile class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the CloudStorageStream interface and pass the ShareFile class an instance of that concrete class.

 When implementing the CloudStorageStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.

```text
bool CanRead() { return true; }
```

```text
bool CanSeek() { return true; }
```

```text
bool CanWrite() { return true; }
```

```text
int64 GetLength() = 0;
```

```text
void Close() {}
```

```text
int Flush() { return 0; }
```

```text
int Read(void* buffer, int count) = 0;
```

```text
int64 Seek(int64 offset, int seekOrigin) = 0;
```

```text
int Write(const void* buffer, int count) = 0;
```

|  |  |
| --- | --- |
| Properties |  |
| CanRead | Whether the stream supports reading. |
| CanSeek | Whether the stream supports seeking. |
| CanWrite | Whether the stream supports writing. |
| Length | Gets the length of the stream, in bytes. |
| Methods |  |
| Close | Closes the stream, releasing all resources currently allocated for it. This method is called automatically when a CloudStorageStream object is deleted. |
| Flush | Forces all data held by the stream's buffers to be written out to storage. Must return 0 if flushing is successful; or -1 if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return 0. |
| Read | Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read. Buffer specifies the buffer to populate with data from the stream. Count specifies the number of bytes that should be read from the stream. Must return the total number of bytes read into Buffer; this may be less than Count if that many bytes are not currently available, or 0 if the end of the stream has been reached. Must return -1 if an error occurs, if reading is not supported, or if the stream is closed. |
| Seek | Sets the current position within the stream based on a particular point of origin. Offset specifies the offset in the stream to seek to, relative to SeekOrigin. Valid values for SeekOrigin are: 0: Seek from beginning. 1: Seek from current position. 2: Seek from end. Must return the new position within the stream; or -1 if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If -1 is returned, the current position within the stream must remain unchanged. Note: If the stream is not closed, it must always be possible to call this method with an Offset of 0 and a SeekOrigin of 1 to obtain the current position within the stream, even if seeking is not otherwise supported. |
| Write | Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written. Buffer specifies the buffer with data to write to the stream. Count specifies the number of bytes that should be written to the stream. Must return the total number of bytes written to the stream; this may be less than Count if that many bytes could not be written. Must return -1 if an error occurs, if writing is not supported, or if the stream is closed. |

# Config Settings ([ShareFile](#sharefile-class) Class)

 The class accepts one or more of the following *configuration settings*. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these *internal properties* is provided through the [Config](#config-method-sharefile-class) method.

### ShareFile Config Settings

**AccumulatePages**: Whether the class should accumulate subsequent pages of results when listing them.This setting controls how the class behaves when listing multiple pages of results. If this setting is enabled, each successive page of results will be appended to the appropriate collection properties until the last page of results has been listed (at which point the next list call will cause said collection to be cleared first). If this setting is disabled, the collection will be cleared every time a page of results is returned.

By default, this setting is enabled, allowing all pages of results to be accumulated in the appropriate collection properties.

**CreatePermissionNotify**: Whether to notify users of the permission they granted.This setting specifies whether notify users of the permission they granted. If set to True an email will be sent by ShareFile.

The default value is False.

**CreatePermissionNotifyMessage**: The custom notify message used in permission notification email.This setting only applies when CreatePermissionNotify is set to True.

**DeleteChildItemsPermanently**: Whether ChildItems should be deleted permanently.This setting specifies if child items should be deleted permanently by the class. Only available for [DeleteChildItems](#deletechilditems-method-sharefile-class) The default value is False.

**DeleteUserCompletely**: Whether to delete user completely.This setting specifies whether delete user completely.

The default value is False.

**ForceSync**: Whether ShareFile will block the operation from taking place asynchronously.This setting specifies whether ShareFile will execute the operation synchronously. This setting does not affect how this class executes.

The default value is True.

**IncludeDeletedItems**: Whether deleted items should be include in the results.This setting specifies whether deleted items should be included in the results when calling [GetItemInfo](#getiteminfo-method-sharefile-class) or [ListItems](#listitems-method-sharefile-class). Unavailable when using the path.

Note: This setting is not applicable when calling [GetItemInfo](#getiteminfo-method-sharefile-class) and a path is specified.

The default value is False.

**IncludeExpiredLinks**: Whether expired links should be include in the results.This setting specifies whether expired links should be included in the results when calling [GetLinkInfo](#getlinkinfo-method-sharefile-class) or [ListLinks](#listlinks-method-sharefile-class).

The default value is False.

**ListUsersType**: The type used to list users.This setting specifies the type of Users to retrieve. Use 'personal' to retrieve the contact list maintained by the authenticated user; 'shared' to retrieve the account-wide list; and 'group' to retrieve the list of distribution groups in the account.

**RawRequest**: Returns the data that was sent to the server.This setting may be queried after calling any method that sends data to the server to obtain the request data that was transmitted. Such data may be useful for troubleshooting purposes.

**RawResponse**: Returns the data that was received from the server.This setting may be queried after calling any method that sends data to the server to obtain the response data that was received. Such data may be useful for troubleshooting purposes.

**SearchPageSize**: Limits the number of search results.This setting specifies the maximum number of search results to be returned each time [Search](#search-method-sharefile-class) is called. If there are more items than can be returned, the results will be paged and the [SearchMarker](#searchmarker-property-sharefile-class) property populated. Note that in some cases a page of results may have less items than is specified here, even if more pages are available.

The default is -1, which causes the server's default (50) to be used.

**XChildCount**: The number of child elements of the current element.This configuration settings specifies the number of child attributes of the current element. The XChild configuration settings will be indexed from 0 to ([XChildCount](#XChildCount) - 1).

The current element is specified through the [XPath](#XPath) configuration setting. This configuration setting is read-only.

**XChildName[i]**: The name of the child element.This configuration setting provides the name of the i-th child element of the current element.

The current element is specified through the [XPath](#XPath) configuration setting. This configuration setting is read-only.

**XChildXText[i]**: The inner text of the child element.This configuration setting provides the inner text of the i-th child element of the current element.

The current element is specified through the [XPath](#XPath) configuration setting. This configuration setting is read-only.

**XElement**: The name of the current element.This configuration setting provides the name of the current element.

The current element is specified through the [XPath](#XPath) configuration setting. This configuration setting is read-only.

**XParent**: The parent of the current element.This configuration setting provides the parent of the current element.

The current element is specified through the [XPath](#XPath) configuration setting. This configuration setting is read-only.

**XPath**: Provides a way to point to a specific element in the returned XML or JSON response.The [XPath](#XPath) setting allows you to point to specific elements in the XML or JSON response.

When [XPath](#XPath) is set to a valid path, [XElement](#XElement) points to the name of the element, with [XText](#XText), [XParent](#XParent), [XSubTree](#XSubTree), [XChildCount](#XChildCount), [XChildName\[i\]](#XChildName[i]), and [XChildXText\[i\]](#XChildXText[i]) providing other properties of the element.

XPath syntax is available for both XML and JSON documents. An XPath is a series of one or more element accessors separated by the */* character, for example, */A/B/C/D*. An XPath can be absolute (i.e., it starts with */*), or it can be relative to the current [XPath](#XPath) location.

The following are possible values for an element accessor, which operates relative to the current location specified by the XPath accessors, which proceed it in the overall XPath string:

| Accessor | Description |
| --- | --- |
| name | The first element with a particular name. Can be *. |
| [i] | The i-th element. |
| name[i] | The i-th element with a particular name. |
| [last()] | The last element. |
| [last()-i] | The element i before the last element. |
| name[@attrname="attrvalue"] | The first element with a particular name that contains the specified attribute-value pair. Supports single and double quotes. (XML Only) |
| . | The current element. |
| .. | The parent element. |

 NOTE: XPath indices are *1-based*.

For example, assume the following XML and JSON responses.

XML:

```text
<firstlevel>
  <one>value</one>
  <two>
    <item>first</item>
    <item>second</item>
  </two>
  <three>value three</three>
</firstlevel>
```

JSON:

```text
{
  "firstlevel": {
    "one": "value",
    "two": ["first", "second"],
    "three": "value three"
  }
}
```

The following are examples of valid XPaths for these responses:

| Description | XML XPath | JSON XPath |
| --- | --- | --- |
| Document root | / | /json |
| Specific element | /firstlevel/one | /json/firstlevel/one |
| i-th child | /firstlevel/two/item[2] | /json/firstlevel/two/[2] |

This list is not exhaustive, but it provides a general idea of the possibilities.

**XSubTree**: A snapshot of the current element in the document.This configuration setting provides the entirety of the current element (including its subelements).

The current element is specified through the [XPath](#XPath) configuration setting. This configuration setting is read-only.

**XText**: The text of the current element.This configuration setting provides the inner text of the current element.

The current element is specified in the [XPath](#XPath) configuration setting. This configuration setting is read-only.

### OAuth Config Settings

**OAuthAccessTokenExpiration**: The lifetime of the access token.This setting holds the lifetime of the access token in seconds. For instance the value *3600* indicates that the token will expire in one hour from the time it was generated.

**OAuthAuthorizationTokenType**: The type of access token returned.The applicable values include the following:

|  |  |
| --- | --- |
| Bearer (default) | When the access token returned by the server is a Bearer type, the authorization string returned by [Authorize](#authorize-method-sharefile-class) will be in the format "Bearer access_token". This can be supplied as the value of the HTTP Authorization header. |

**OAuthAutomaticRefresh**: Whether or not to refresh an expired access token automatically.When this setting is set to *true* and the [Authorization](#authorization-property-sharefile-class) property is not set, the class will automatically get a new access token if it has the necessary properties to do so without user interaction.

For example, when using the Authorization Code grant type, the [RefreshToken](#OAuthSettings_f_RefreshToken) field should be set to a valid refresh token. When using the Client Credential grant type however, the class does not need any additional properties set as it can already get a new access token without user interaction.

**OAuthBrowserResponseTimeout**: Specifies the amount of time to wait for a response from the browser.This setting specifies the amount of time (in seconds) the class will wait for a response from the browser when requesting user authentication. The default value is *0*, meaning that the class will wait indefinitely.

**OAuthIncludeEmptyRedirectURI**: Whether an empty redirect_uri parameter is included in requests.This setting specifies whether *redirect_uri* is included in the request made by [Authorize](#authorize-method-sharefile-class) if it is empty.

If set to *true* (default) the *redirect_uri* will be sent in all cases. If set to *false* the *redirect_uri* will only be sent if it has a value.

**OAuthJWTPayload**: The payload of the JWT access token if present.This configuration setting provides the payload section of a JWT access token if the access token is a JWT and the class is able to parse out the payload section. This setting only applies to **access tokens** that are returned from a service provider after successfully authorizing and authenticating with the service.

To parse the payload for specific claims, see [OAuthJWTXPath](#OAuthJWTXPath).

**OAuthJWTXChildCount**: The number of child elements of the current element.The number of child attributes of the current element. The OAuthJWTXChildCount configuration settings will be indexed from 0 to ([OAuthJWTXChildCount](#OAuthJWTXChildCount) - 1).

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OauthJWTXChildName[i]**: The name of the child element.Provides the name of the i'th child element of the current element.

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OAuthJWTXChildXText[i]**: The inner text of the child element.Provides the inner text of the i'th child element of the current element.

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OAuthJWTXElement**: The name of the current element.Provides the name of the current element.

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OauthJWTXParent**: The parent of the current element.Provides the parent of the current element.

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OAuthJWTXPath**: Provides a way to point to a specific element in the returned payload of a JWT based access token.The [OAuthJWTXPath](#OAuthJWTXPath) setting allows you to point to specific claims within the payload of a JWT based access token.

XPath syntax is available for the payload of JWT based access tokens if available. An XPath is a series of one or more element accessors separated by the */* character, for example: */A/B/C/D*.

The following are possible values for an element accessor, which operates relative to the current location specified by the XPath accessors which proceed it in the overall XPath string:

| Accessor | Description |
| --- | --- |
| name | The first element with a particular name. Can be *. |
| [i] | The i-th element. |
| name[i] | The i-th element with a particular name. |
| [last()] | The last element. |
| [last()-i] | The element i before the last element. |

 Here are some examples of valid XPaths and some common claims:

| Description | JSON XPath |
| --- | --- |
| Document root | /json |
| Specific element | /json/element_one |
| Username Claim (Microsoft Specific) | /json/preferred_username |
| Registered Application Name Claim (Microsoft Specific) | /json/app_displayname |

This is not an exhaustive list by any means, but should provide a general idea of the possibilities. To get the text of the specified element, see [OAuthJWTXText](#OAuthJWTXText).

**OAuthJWTXSubTree**: A snapshot of the current element in the document.Provides the entirety of the current element (including its sub-elements).

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OAuthJWTXText**: The text of the current element.Provides the inner text of the current element.

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OAuthParamCount**: Specifies the number of additional parameters variables to include in the request.This setting can be used to add query string parameters to the outgoing request. One common use for this method would be to add the "state" parameter to the request, which can be used when the [ClientProfile](#OAuthSettings_f_ClientProfile) is cocpWeb to add user defined data. The authorization server will include the "state" parameter in the response and will be available in the post back to your server which will allow you to maintain state in your application. This is used in conjunction with OAuthParamName[i] and OAuthParamValue[i]. For instance:

```text
component.Config("OAuthParamCount=2");
component.Config("OAuthParamName[0]=myvar");
component.Config("OAuthParamValue[0]=myvalue");
component.Config("OAuthParamName[1]=testname");
component.Config("OAuthParamValue[1]=testvalue");
```

Additionally, this will also be updated to hold the parameters returned in the response.

```text
for (int i = 0; i < int.Parse(component.Config("OAuthParamCount")); i++)
{
  string name = component.Config("OAuthParamName[" + i + "]");
  string value = component.Config("OAuthParamValue[" + i + "]");
}
```

**OAuthParamName[i]**: Specifies the parameter name at the specified index.This setting can be used to retrieve or specify the parameter variable name at the index specified. See [OAuthParamCount](#OAuthParamCount) for details.

**OAuthParamValue[i]**: Specifies the parameter value at the specified index.This setting can be used to retrieve or specify the parameter variable value at the index specified. See [OAuthParamCount](#OAuthParamCount) for details.

**OAuthPasswordGrantUsername**: Used in the Resource Owner Password grant type.Used to set the username field when the [GrantType](#OAuthSettings_f_GrantType) is set to the password grant type and [Authorize](#authorize-method-sharefile-class) is called.

**OAuthPKCEChallengeEncoding**: The PKCE code challenge method to use.This setting controls the PKCE code challenge method used when [OAuthUsePKCE](#OAuthUsePKCE) is set to *true*. Possible values are:

- 1 (Plain)
- 2 (S256/SHA256 - default)

**OAuthPKCEVerifier**: The PKCE verifier used to generate the challenge.This configuration setting when queried provides the PKCE verifier that is used to generate the PKCE challenge for the [Authorize](#authorize-method-sharefile-class) method and the [WebAuthURL](#OAuthSettings_f_WebAuthURL) field when [OAuthUsePKCE](#OAuthUsePKCE) is set to true. When using the cocpWeb [ClientProfile](#OAuthSettings_f_ClientProfile), the configuration setting can be set instead to allow the authorization request to be made from a different instance than the authentication (token) request.

**OAuthResetData**: Determines if the Reset method applies to the OAuth settings.If set to *true* (default), the [Reset](#reset-method-sharefile-class) method will reset the OAuth settings including any authorization fields like [AccessToken](#OAuthSettings_f_AccessToken) and [RefreshToken](#OAuthSettings_f_RefreshToken). This means the [Authorize](#authorize-method-sharefile-class) method must be called again to get new authorization information. When set to *false*, the [Reset](#reset-method-sharefile-class) method will **not** reset the [OAuth](#oauth-property-sharefile-class) property and the OAuth* configuration settings. This allows for the class to be reset without having to get authorization again.

**OAuthReUseWebServer**: Determines if the same server instance is used between requests.If set to *true* (default), the same embedded web server instance will be used for multiple requests. If set to *false* the embedded web server will be created and destroyed on each call to [Authorize](#authorize-method-sharefile-class)

**OAuthTransferredRequest**: The full OAuth request last sent by the client.This configuration setting returns the full OAuth request last sent by the client. For performance reasons, the request is not normally saved. Set this configuration setting to ON before making a request to enable it. Following are examples of this request:

.NET

```text
Gmail gmail = new Gmail();
gmail.Config("OAuthTransferredRequest=on");
gmail.Authorize();
Console.WriteLine(gmail.Config("OAuthTransferredRequest"));
```

 C++

```text
Gmail gmail;
gmail.Config("OAuthTransferredRequest=on");
gmail.Authorize();
printf("%s\r\n", gmail.Config("OAuthTransferredRequest"));
```

**OAuthUsePKCE**: Specifies if PKCE should be used.If set to *true* (default), Proof Key for Code Exchange (PKCE) defined by RFC 7636 will be used when performing authorization. This setting applies when using the Authorization Code [GrantType](#OAuthSettings_f_GrantType). The [OAuthPKCEChallengeEncoding](#OAuthPKCEChallengeEncoding) configuration setting can be used to control the code challenge method that will be used.

**OAuthWebServerActive**: Specifies and controls whether the embedded web server is active.The setting when queried will return the current state of the web server. If the webserver is active, it will return *"true"* and if it is inactive it will return *"false"*.

This setting can also be set to activate or deactivate the web server. Under normal circumstances, this would not be required as the class will automatically start and stop the web server when [Authorize](#authorize-method-sharefile-class) is called. In certain cases, it is required to start the webserver before calling [Authorize](#authorize-method-sharefile-class). For example, if the [ReturnURL](#OAuthSettings_f_ReturnURL) needs to be set to a relay server, then you will need to start the web server manually. Another example would be when the [OAuthReUseWebServer](#OAuthReUseWebServer) is set to true, the server will not be automatically stopped, and this configuration setting must be set to *"false"* to stop the embedded web server.

**OAuthWebServerCertStore**: The certificate with private key to use when SSL is enabled.The name of the certificate store used for the embedded web server's SSL.

The [OAuthWebServerCertStoreType](#OAuthWebServerCertStoreType) field specifies the type of the certificate store specified by [OAuthWebServerCertStore](#OAuthWebServerCertStore). If the store is password protected, specify the password in [OAuthWebServerCertStorePassword](#OAuthWebServerCertStorePassword).

[OAuthWebServerCertStore](#OAuthWebServerCertStore) is used in conjunction with the [OAuthWebServerCertSubject](#OAuthWebServerCertSubject) field in order to specify the certificate to be used during SSL.

 Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

|  |  |
| --- | --- |
| MY | A certificate store holding personal certificates with their associated private keys. |
| CA | Certifying authority certificates. |
| ROOT | Root certificates. |

When the certificate store type is *cstPFXFile*, this property must be set to the name of the file. When the type is *cstPFXBlob*, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

Note: This is required when [OAuthWebServerSSLEnabled](#OAuthWebServerSSLEnabled) is set to *true*.

**OAuthWebServerCertStorePassword**: The certificate with private key to use when SSL is enabled.If the certificate store is of a type that requires a password, this property is used to specify that password in order to open the certificate store.

Note: This is only applicable when [OAuthWebServerSSLEnabled](#OAuthWebServerSSLEnabled) is set to *true*.

**OAuthWebServerCertStoreType**: The certificate with private key to use when SSL is enabled.This specifies the type of certificate store. Possible values are:

|  |  |
| --- | --- |
| 0 | User - This is the default for Windows. This specifies that the certificate store is a certificate store owned by the current user. NOTE: This store type is not available in Java. |
| 1 | Machine - For Windows, this specifies that the certificate store is a machine store. NOTE: This store type is not available in Java. |
| 2 | PFXFile - The certificate store is the name of a PFX (PKCS12) file containing certificates. |
| 3 | PFXBlob - The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS12) format. |
| 4 | JKSFile - The certificate store is the name of a Java Key Store (JKS) file containing certificates. NOTE: This store type is available only in Java. |
| 5 | JKSBlob - The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format. NOTE: This store type is available only in Java. |
| 6 | PEMKeyFile - The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate. |
| 7 | PEMKeyBlob - The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate. |
| 14 | PPKFile - The certificate store is the name of a file that contains a PPK (PuTTY Private Key). |
| 15 | PPKBlob - The certificate store is a string (binary) that contains a PPK (PuTTY Private Key). |
| 16 | XMLFile - The certificate store is the name of a file that contains a certificate in XML format. |
| 17 | XMLBlob - The certificate store is a string that contains a certificate in XML format. |

 Note: This is required when [OAuthWebServerSSLEnabled](#OAuthWebServerSSLEnabled) is set to *true*.

**OAuthWebServerCertSubject**: The certificate with private key to use when SSL is enabled.The subject of the SSL certificate.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=example@email.com". Common fields and their meanings are as follows:

| Field | Meaning |
| --- | --- |
| CN | Common Name. This is commonly a hostname like www.server.com. |
| O | Organization |
| OU | Organizational Unit |
| L | Locality |
| S | State |
| C | Country |
| E | Email Address |

If a field value contains a comma, it must be quoted.

Note: This is required when [OAuthWebServerSSLEnabled](#OAuthWebServerSSLEnabled) is set to *true*.

**OAuthWebServerFailedResponse**: The custom response that will be displayed to the user if authentication failed.When [Authorize](#authorize-method-sharefile-class) is called the user will be redirected to the embedded web server upon completing authentication with the authorization server. If authentication failed, the HTML specified here will be sent to the user's browser.

**OAuthWebServerHost**: The hostname used by the embedded web server displayed in the ReturnURL.This setting specifies the hostname used by the embedded web server when [ClientProfile](#OAuthSettings_f_ClientProfile) is set to cocpApplication. This specifies the interface on which the embedded web server listens, and also the value displayed in the [ReturnURL](#OAuthSettings_f_ReturnURL). This should be set to the hostname only, not the full URL.

The default value is *localhost*.

**OAuthWebServerPort**: The local port on which the embedded web server listens.This property specifies the port on which the embedded web server listens. Setting this to *0* (default) enables the system to choose a port at random. The chosen port will be returned when this setting is queried after the server has started listening.This is only applicable when using the embedded web server.

**OAuthWebServerResponse**: The custom response that will be displayed to the user.When [Authorize](#authorize-method-sharefile-class) is called the user will be redirected to the embedded web server upon completing authentication with the authorization server. This setting allows you to specify the HTML that will be sent to the user's browser.

**OAuthWebServerSSLEnabled**: Whether the web server requires SSL connections.This setting specifies whether the embedded web server will use SSL. If set to *True* OAuthWebServerCert* configs are required and the server will only accept SSL connections. If set to *False* only plaintext connects are supported.

### HTTP Config Settings

**AcceptEncoding**: Used to tell the server which types of content encodings the client supports.When [AllowHTTPCompression](#AllowHTTPCompression) is True, the class adds an *Accept-Encoding* header to the request being sent to the server. By default, this header's value is "gzip, deflate". This configuration setting allows you to change the value of the *Accept-Encoding* header. NOTE: The class only supports gzip and deflate decompression algorithms.

**AllowHTTPCompression**: This property enables HTTP compression for receiving data.This configuration setting enables HTTP compression for receiving data. When set to True (default), the class will accept compressed data. It then will uncompress the data it has received. The class will handle data compressed by both gzip and deflate compression algorithms.

When True, the class adds an *Accept-Encoding* header to the outgoing request. The value for this header can be controlled by the [AcceptEncoding](#AcceptEncoding) configuration setting. The default value for this header is "gzip, deflate".

The default value is True.

**AllowHTTPFallback**: Whether HTTP/2 connections are permitted to fallback to HTTP/1.1.This configuration setting controls whether HTTP/2 connections are permitted to fall back to HTTP/1.1 when the server does not support HTTP/2. This setting is applicable only when HTTPVersion is set to "2.0".

If set to True (default), the class will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the class fails with an error if the server does not support HTTP/2.

The default value is True.

**Append**: Whether to append data to LocalFile.This configuration setting determines whether data will be appended when writing to [LocalFile](#localfile-property-sharefile-class). When set to True, downloaded data will be appended to [LocalFile](#localfile-property-sharefile-class). This may be used in conjunction with Range to resume a failed download. This is applicable only when [LocalFile](#localfile-property-sharefile-class) is set. The default value is False.

**Authorization**: The Authorization string to be sent to the server.If the [Authorization](#Authorization) property contains a nonempty string, an *Authorization* HTTP request header is added to the request. This header conveys Authorization information to the server.

This property is provided so that the HTTP class can be extended with other security schemes in addition to the authorization schemes already implemented by the class.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the [Authorization](#authorization-property-sharefile-class) property in the form "Basic [encoded-user-password]".

**BytesTransferred**: Contains the number of bytes transferred in the response data.This configuration setting returns the raw number of bytes from the HTTP response data, before the component processes the data, whether it is chunked or compressed. This returns the same value as the [Transfer](#transfer-event-sharefile-class) event, by [BytesTransferred](#BytesTransferred).

**ChunkSize**: Specifies the chunk size in bytes when using chunked encoding.This is applicable only when [UseChunkedEncoding](#UseChunkedEncoding) is True. This setting specifies the chunk size in bytes to be used when posting data. The default value is 16384.

**CompressHTTPRequest**: Set to true to compress the body of a PUT or POST request.If set to True, the body of a *PUT* or *POST* request will be compressed into gzip format before sending the request. The "Content-Encoding" header is also added to the outgoing request.

The default value is False.

**EncodeURL**: If set to True the URL will be encoded by the class.If set to True, the URL passed to the class will be URL encoded. The default value is False.

**FollowRedirects**: Determines what happens when the server issues a redirect.This option determines what happens when the server issues a redirect. Normally, the class returns an error if the server responds with an "Object Moved" message. If this property is set to 1 (always), the new URL for the object is retrieved automatically every time.

If this property is set to 2 (Same Scheme), the new URL is retrieved automatically only if the URL Scheme is the same; otherwise, the class fails with an error.

**Note:** Following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for *GET* or *HEAD* requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is 0 (Never). In this case, redirects are never followed, and the class fails with an error instead.

Following are the valid options:

- 0 - Never
- 1 - Always
- 2 - Same Scheme

**GetOn302Redirect**: If set to True the class will perform a GET on the new location.The default value is False. If set to True, the class will perform a *GET* on the new location. Otherwise, it will use the same HTTP method again.

**HTTP2HeadersWithoutIndexing**: HTTP2 headers that should not update the dynamic header table with incremental indexing.HTTP/2 servers maintain a dynamic table of headers and values seen over the course of a connection. Typically, these headers are inserted into the table through incremental indexing (also known as HPACK, defined in RFC 7541). To tell the component not to use incremental indexing for certain headers, and thus not update the dynamic table, set this configuration option to a comma-delimited list of the header names.

**HTTPVersion**: The version of HTTP used by the class.This property specifies the HTTP version used by the class. Possible values are as follows:

- "1.0"
- "1.1" (default)
- "2.0"
- "3.0"

When using HTTP/2 ("2.0") or HTTP/3 ("3.0"), additional restrictions apply. Please see the following notes for details.

**HTTP/2 Notes**

When using HTTP/2, a secure Secure Sockets Layer/Transport Layer Security (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/2 will result in an error.

If the server does not support HTTP/2, the class will automatically use HTTP/1.1 instead. This is done to provide compatibility without the need for any additional settings. To see which version was used, check [NegotiatedHTTPVersion](#NegotiatedHTTPVersion) after calling a method. The [AllowHTTPFallback](#AllowHTTPFallback) setting controls whether this behavior is allowed (default) or disallowed.

**HTTP/3 Notes**

HTTP/3 is supported only in .NET and Java.

When using HTTP/3, a secure (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/3 will result in an error.

**IfModifiedSince**: A date determining the maximum age of the desired document.If this setting contains a nonempty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the component throws an exception

The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example:

```text
Sat, 29 Oct 2017 19:43:31 GMT.
```

**KeepAlive**: Determines whether the HTTP connection is closed after completion of the request.If *true*, the component will not send the *Connection: Close* header. The absence of the Connection header indicates to the server that HTTP persistent connections should be used if supported. NOTE: Not all servers support persistent connections. If *false*, the connection will be closed immediately after the server response is received.

 The default value for [KeepAlive](#KeepAlive) is *false*.

**KerberosSPN**: The Service Principal Name for the Kerberos Domain Controller.If the Service Principal Name on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, the Service Principal Name should be set here.

**LogLevel**: The level of detail that is logged.This configuration setting controls the level of detail that is logged through the [Log](#log-event-sharefile-class) event. Possible values are as follows:

|  |  |
| --- | --- |
| 0 (None) | No events are logged. |
| 1 (Info - default) | Informational events are logged. |
| 2 (Verbose) | Detailed data are logged. |
| 3 (Debug) | Debug data are logged. |

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

**MaxRedirectAttempts**: Limits the number of redirects that are followed in a request.When FollowRedirects is set to any value other than frNever, the class will follow redirects until this maximum number of redirect attempts are made. The default value is 20.

**NegotiatedHTTPVersion**: The negotiated HTTP version.This configuration setting may be queried after the request is complete to indicate the HTTP version used. When HTTPVersion is set to "2.0" (if the server does not support "2.0"), then the class will fall back to using "1.1" automatically. This setting will indicate which version was used.

**OtherHeaders**: Other headers as determined by the user (optional).This configuration setting can be set to a string of headers to be appended to the HTTP request headers.

The headers must follow the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF (*"\r\n"*) .

Use this configuration setting with caution. If this configuration setting contains invalid headers, HTTP requests may fail.

This configuration setting is useful for extending the functionality of the class beyond what is provided.

**ProxyAuthorization**: The authorization string to be sent to the proxy server.This is similar to the [Authorization](#Authorization) configuration setting, but is used for proxy authorization. If this configuration setting contains a nonempty string, a *Proxy-Authorization* HTTP request header is added to the request. This header conveys proxy Authorization information to the server. If [User](#Proxy_f_User) and [Password](#Proxy_f_Password) are specified, this value is calculated using the algorithm specified by [AuthScheme](#Proxy_f_AuthScheme).

**ProxyAuthScheme**: The authorization scheme to be used for the proxy.This configuration setting is provided for use by classes that do not directly expose Proxy properties.

**ProxyPassword**: A password if authentication is to be used for the proxy.This configuration setting is provided for use by classes that do not directly expose Proxy properties.

**ProxyPort**: Port for the proxy server (default 80).This configuration setting is provided for use by classes that do not directly expose Proxy properties.

**ProxyServer**: Name or IP address of a proxy server (optional).This configuration setting is provided for use by classes that do not directly expose Proxy properties.

**ProxyUser**: A user name if authentication is to be used for the proxy.This configuration setting is provided for use by classes that do not directly expose Proxy properties.

**SentHeaders**: The full set of headers as sent by the client.This configuration setting returns the complete set of raw headers as sent by the client.

**StatusCode**: The status code of the last response from the server.This configuration setting contains the result code of the last response from the server.

**StatusLine**: The first line of the last response from the server.This setting contains the first line of the last response from the server. The format of the line will be *[HTTP version] [Result Code] [Description]*.

**TransferredData**: The contents of the last response from the server.This configuration setting contains the contents of the last response from the server.

**TransferredDataLimit**: The maximum number of incoming bytes to be stored by the class.If [TransferredDataLimit](#TransferredDataLimit) is set to 0 (default), no limits are imposed. Otherwise, this reflects the maximum number of incoming bytes that can be stored by the class.

**TransferredHeaders**: The full set of headers as received from the server.This configuration setting returns the complete set of raw headers as received from the server.

**TransferredRequest**: The full request as sent by the client.This configuration setting returns the full request as sent by the client. For performance reasons, the request is not normally saved. Set this configuration setting to ON before making a request to enable it. Following are examples of this request:

 .NET

```text
Http http = new Http();
http.Config("TransferredRequest=on");
http.PostData = "body";
http.Post("http://someserver.com");
Console.WriteLine(http.Config("TransferredRequest"));
```

 C++

```text
HTTP http;
http.Config("TransferredRequest=on");
http.SetPostData("body", 5);
http.Post("http://someserver.com");
printf("%s\r\n", http.Config("TransferredRequest"));
```

**UseChunkedEncoding**: Enables or Disables HTTP chunked encoding for transfers.If [UseChunkedEncoding](#UseChunkedEncoding) is set to True, the class will use HTTP-chunked encoding when posting, if possible. HTTP-chunked encoding allows large files to be sent in chunks instead of all at once. If set to False, the class will not use HTTP-chunked encoding. The default value is False.

NOTE: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.

**UseIDNs**: Whether to encode hostnames to internationalized domain names.This configuration setting specifies whether hostnames containing non-ASCII characters are encoded to internationalized domain names. When set to True, if a hostname contains non-ASCII characters, it is encoded using Punycode to an IDN (internationalized domain name).

The default value is False and the hostname will always be used exactly as specified. NOTE: The [CodePage](#CodePage) setting must be set to a value capable of interpreting the specified host name. For instance, to specify UTF-8, set [CodePage](#CodePage) to *65001*. In the C++ Edition for Windows, the *W version of the class must be used. For instance, *DNSW* or *HTTPW*.

**UsePlatformHTTPClient**: Whether or not to use the platform HTTP client.When using this configuration setting, if True, the component will use the default HTTP client for the platform (*URLConnection* in Java, *WebRequest* in .NET, or CFHTTPMessage in Mac/iOS) instead of the internal HTTP implementation. This is important for environments in which direct access to sockets is limited or not allowed (e.g., in the Google AppEngine).

NOTE: This setting is applicable only to Mac/iOS editions.

**UseProxyAutoConfigURL**: Whether to use a Proxy auto-config file when attempting a connection.This configuration specifies whether the class will attempt to use the Proxy auto-config URL when establishing a connection and [AutoDetect](#Proxy_f_AutoDetect) is set to *True*.

When *True* (default), the class will check for the existence of a Proxy auto-config URL, and if found, will determine the appropriate proxy to use.

**UserAgent**: Information about the user agent (browser).This is the value supplied in the HTTP User-Agent header. The default setting is "IPWorks HTTP Component - www.nsoftware.com".

Override the default with the name and version of your software.

### TCPClient Config Settings

**ConnectionTimeout**: Sets a separate timeout value for establishing a connection.When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the class will use [Timeout](#timeout-property-sharefile-class) for establishing a connection and transmitting/receiving data.

**FirewallAutoDetect**: Tells the class whether or not to automatically detect and use firewall system settings, if available.This configuration setting is provided for use by classes that do not directly expose Firewall properties.

**FirewallHost**: Name or IP address of firewall (optional).If a [FirewallHost](#FirewallHost) is given, requested connections will be authenticated through the specified firewall when connecting.

If the [FirewallHost](#FirewallHost) setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the [FirewallHost](#FirewallHost) setting is set to the corresponding address. If the search is not successful, an error is returned.

NOTE: This setting is provided for use by classes that do not directly expose Firewall properties.

**FirewallHTTPVersion**: The HTTP version to be used when connecting through a tunneling proxy.When [FirewallType](#FirewallType) is set to a tunneling proxy, this setting dictates which HTTP version is used when connecting.

**FirewallPassword**: Password to be used if authentication is to be used when connecting through the firewall.If [FirewallHost](#FirewallHost) is specified, the [FirewallUser](#FirewallUser) and [FirewallPassword](#FirewallPassword) settings are used to connect and authenticate to the given firewall. If the authentication fails, the class fails with an error.

NOTE: This setting is provided for use by classes that do not directly expose Firewall properties.

**FirewallPort**: The TCP port for the FirewallHost;.The [FirewallPort](#FirewallPort) is set automatically when [FirewallType](#FirewallType) is set to a valid value.

NOTE: This configuration setting is provided for use by classes that do not directly expose Firewall properties.

**FirewallType**: Determines the type of firewall to connect through.Possible values are as follows:

|  |  |
| --- | --- |
| 0 | No firewall (default setting). |
| 1 | Connect through a tunneling proxy. [FirewallPort](#FirewallPort) is set to 80. |
| 2 | Connect through a SOCKS4 Proxy. [FirewallPort](#FirewallPort) is set to 1080. |
| 3 | Connect through a SOCKS5 Proxy. [FirewallPort](#FirewallPort) is set to 1080. |
| 10 | Connect through a SOCKS4A Proxy. [FirewallPort](#FirewallPort) is set to 1080. |

NOTE: This setting is provided for use by classes that do not directly expose Firewall properties.

**FirewallUser**: A user name if authentication is to be used connecting through a firewall.If the [FirewallHost](#FirewallHost) is specified, the [FirewallUser](#FirewallUser) and [FirewallPassword](#FirewallPassword) settings are used to connect and authenticate to the Firewall. If the authentication fails, the class fails with an error.

NOTE: This setting is provided for use by classes that do not directly expose Firewall properties.

**KeepAliveInterval**: The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.When set, [TCPKeepAlive](#TCPKeepAlive) will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by [KeepAliveTime](#KeepAliveTime). If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

NOTE: This value is not applicable in macOS.

**KeepAliveRetryCount**: The number of keep-alive packets to be sent before the remotehost is considered disconnected.When set, [TCPKeepAlive](#TCPKeepAlive) will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by [KeepAliveTime](#KeepAliveTime). If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the number of times that the keep-alive packets will be sent before the remote host is considered disconnected. The system default if this value is not specified here is 9.

NOTE: This configuration setting is only available in the Unix platform. It is not supported in masOS or FreeBSD.

**KeepAliveTime**: The inactivity time in milliseconds before a TCP keep-alive packet is sent.When set, [TCPKeepAlive](#TCPKeepAlive) will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

**Linger**: When set to True, connections are terminated gracefully.This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if [LingerTime](#LingerTime) is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if [LingerTime](#LingerTime) is a positive value, the system will attempt to send pending data until the specified [LingerTime](#LingerTime) is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

**LingerTime**: Time in seconds to have the connection linger. LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

**LocalHost**: The name of the local host through which connections are initiated or accepted. The [LocalHost](#localhost-property-sharefile-class) setting contains the name of the local host as obtained by the *gethostname()* system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classes) only through that interface.

If the class is connected, the [LocalHost](#localhost-property-sharefile-class) setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

**LocalPort**: The port in the local host where the class binds. This configuration setting must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.

**MaxLineLength**: The maximum amount of data to accumulate when no EOL is found.[MaxLineLength](#MaxLineLength) is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before [MaxLineLength](#MaxLineLength) bytes are received, the DataIn event is fired with the *EOL* parameter set to True, and the buffer is reset.

If no EOL is found, and [MaxLineLength](#MaxLineLength) bytes are accumulated in the buffer, the DataIn event is fired with the *EOL* parameter set to False, and the buffer is reset.

The minimum value for [MaxLineLength](#MaxLineLength) is 256 bytes. The default value is 2048 bytes.

**MaxTransferRate**: The transfer rate limit in bytes per second.This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

**ProxyExceptionsList**: A semicolon separated list of hosts and IPs to bypass when using a proxy.This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

*www.google.com;www.example.com*

**TCPKeepAlive**: Determines whether or not the keep alive socket option is enabled.If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set [KeepAliveTime](#KeepAliveTime) and [KeepAliveInterval](#KeepAliveInterval) to configure the timing of the keep-alive packets.

NOTE: This value is not applicable in Java.

**TcpNoDelay**: Whether or not to delay when sending packets. When set to True, the socket will send all data that are ready to send at once. When set to False, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this configuration setting is set to False.

**UseIPv6**: Whether to use IPv6.When set to *0* (default), the class will use IPv4 exclusively. When set to *1*, the class will use IPv6 exclusively. To instruct the class to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to *2*. The default value is *0*. Possible values are as follows:

|  |  |
| --- | --- |
| 0 | IPv4 only |
| 1 | IPv6 only |
| 2 | IPv6 with IPv4 fallback |

**UseNTLMv2**: Whether to use NTLM V2.When authenticating with NTLM, this setting specifies whether NTLM V2 is used. By default this value is True and NTLM V2 will be used. Set this to False to use NTLM V1.

### SSL Config Settings

**LogSSLPackets**: Controls whether SSL packets are logged when using the internal security API.When [SSLProvider](#sslprovider-property-sharefile-class) is set to *Internal*, this configuration setting controls whether Secure Sockets Layer (SSL) packets should be logged. By default, this configuration setting is *False*, as it is useful only for debugging purposes.

When enabled, SSL packet logs are output using the [SSLStatus](#sslstatus-event-sharefile-class) event, which will fire each time an SSL packet is sent or received.

Enabling this configuration setting has no effect if [SSLProvider](#sslprovider-property-sharefile-class) is set to *Platform*.

**OpenSSLCADir**: The path to a directory containing CA certificates.This functionality is available only when the provider is OpenSSL.

The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g., 9d66eef0.0, 9d66eef0.1). OpenSSL recommends the use of the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

**OpenSSLCAFile**: Name of the file containing the list of CA's trusted by your application.This functionality is available only when the provider is OpenSSL.

The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by the following sequences:

 -----BEGIN CERTIFICATE-----

 ... (CA certificate in base64 encoding) ...

 -----END CERTIFICATE-----

 Before, between, and after the certificate text is allowed, which can be used, for example, for descriptions of the certificates. Refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

**OpenSSLCipherList**: A string that controls the ciphers to be used by SSL.This functionality is available only when the provider is OpenSSL.

The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".

**OpenSSLPrngSeedData**: The data to seed the pseudo random number generator (PRNG).This functionality is available only when the provider is OpenSSL.

By default, OpenSSL uses the device file "/dev/urandom" to seed the PRNG, and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.

**ReuseSSLSession**: Determines if the SSL session is reused.

If set to True, the class will reuse the context if and only if the following criteria are met:

- The target host name is the same.
- The system cache entry has not expired (default timeout is 10 hours).
- The application process that calls the function is the same.
- The logon session is the same.
- The instance of the class is the same.

**SSLCACertFilePaths**: The paths to CA certificate files on Unix/Linux.This configuration setting specifies the paths on disk to CA certificate files on Unix/Linux.

The value is formatted as a list of paths separated by semicolons. The class will check for the existence of each file in the order specified. When a file is found, the CA certificates within the file will be loaded and used to determine the validity of server or client certificates.

The default value is as follows:

*/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem*

**SSLCACerts**: A newline separated list of CA certificates to be included when performing an SSL handshake.When [SSLProvider](#sslprovider-property-sharefile-class) is set to *Internal*, this configuration setting specifies one or more CA certificates to be included with the [SSLCert](#sslcert-property-sharefile-class) property. Some servers or clients require the entire chain, including CA certificates, to be presented when performing SSL authentication. The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

```text
-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert ...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----

... Root Cert ...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----
```

**SSLCipherStrength**: The minimum cipher strength used for bulk encryption. This minimum cipher strength is largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

NOTE: This configuration setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the [SSLStatus](#sslstatus-event-sharefile-class) event.

Use this configuration setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, [SSLCipherStrength](#SSLCipherStrength) is currently not supported. This functionality is instead made available through the [OpenSSLCipherList](#OpenSSLCipherList) configuration setting.

**SSLClientCACerts**: A newline separated list of CA certificates to use during SSL client certificate validation.This configuration setting is only applicable to server components (e.g., TCPServer) see [SSLServerCACerts](#SSLServerCACerts) for client components (e.g., TCPClient). This setting can be used to optionally specify one or more CA certificates to be used when verifying the client certificate that is presented by the client during the SSL handshake when SSLAuthenticateClients is enabled. When verifying the client's certificate, the certificates trusted by the system will be used as part of the verification process. If the client's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the client's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

```text
-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert ...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----
MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp
... Root Cert ...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----
```

**SSLEnabledCipherSuites**: The cipher suite to be used in an SSL negotiation.This configuration setting enables the cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the class will pick all of the supported cipher suites. If [SSLEnabledCipherSuites](#SSLEnabledCipherSuites) is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

When TLS 1.3 is negotiated (see [SSLEnabledProtocols](#SSLEnabledProtocols)), only the following cipher suites are supported:

- TLS_AES_256_GCM_SHA384
- TLS_CHACHA20_POLY1305_SHA256
- TLS_AES_128_GCM_SHA256

[SSLEnabledCipherSuites](#SSLEnabledCipherSuites) is used together with [SSLCipherStrength](#SSLCipherStrength).

**SSLEnabledProtocols**: Used to enable/disable the supported security protocols.This configuration setting is used to enable or disable the supported security protocols.

Not all supported protocols are enabled by default. The default value is *4032* for client components, and *3072* for server components. To specify a combination of enabled protocol versions set this config to the binary *OR* of one or more of the following values:

|  |  |
| --- | --- |
| TLS1.3 | 12288 (Hex 3000) |
| TLS1.2 | 3072 (Hex C00) (Default - Client and Server) |
| TLS1.1 | 768 (Hex 300) (Default - Client) |
| TLS1 | 192 (Hex C0) (Default - Client) |
| SSL3 | 48 (Hex 30) |
| SSL2 | 12 (Hex 0C) |

Note that only TLS 1.2 is enabled for server components that accept incoming connections. This adheres to industry standards to ensure a secure connection. Client components enable TLS 1.0, TLS 1.1, and TLS 1.2 by default and will negotiate the highest mutually supported version when connecting to a server, which should be TLS 1.2 in most cases.

**SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:**

By default when TLS 1.3 is enabled, the class will first try to use the platform TLS 1.3 implementation when the [SSLProvider](#sslprovider-property-sharefile-class) is set to Automatic for all editions. If the platform TLS 1.3 implementation is not available, the internal implementation will be used.

In editions that are designed to run on Windows, [SSLProvider](#sslprovider-property-sharefile-class) can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is supported only on Windows 11/Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.

If set to *1* (Platform provider), please be aware of the following notes:

- The platform provider is available only on Windows 11/Windows Server 2022 and up.
- [SSLEnabledCipherSuites](#SSLEnabledCipherSuites) and other similar SSL configuration settings are not supported.
- If [SSLEnabledProtocols](#SSLEnabledProtocols) includes both TLS 1.3 and TLS 1.2, these restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.

**SSLEnabledProtocols: SSL2 and SSL3 Notes: **

SSL 2.0 and 3.0 are not supported by the class when the [SSLProvider](#sslprovider-property-sharefile-class) is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and [SSLProvider](#sslprovider-property-sharefile-class) needs to be set to platform.

**SSLEnableRenegotiation**: Whether the renegotiation_info SSL extension is supported.This configuration setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This configuration setting is *false* by default, but it can be set to *true* to enable the extension.

This configuration setting is applicable only when [SSLProvider](#sslprovider-property-sharefile-class) is set to *Internal*.

**SSLIncludeCertChain**: Whether the entire certificate chain is included in the SSLServerAuthentication event.This configuration setting specifies whether the Encoded parameter of the [SSLServerAuthentication](#sslserverauthentication-event-sharefile-class) event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the [SSLServerAuthentication](#sslserverauthentication-event-sharefile-class) event.

If set to True, all certificates returned by the server will be present in the Encoded parameter of the [SSLServerAuthentication](#sslserverauthentication-event-sharefile-class) event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

**SSLKeyLogFile**: The location of a file where per-session secrets are written for debugging purposes.This configuration setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.

When set, the class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools, such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffic for debugging purposes. When writing to this file, the class will only append, it will not overwrite previous values.

NOTE: This configuration setting is applicable only when [SSLProvider](#sslprovider-property-sharefile-class) is set to *Internal*.

**SSLNegotiatedCipher**: Returns the negotiated cipher suite.This configuration setting returns the cipher suite negotiated during the SSL handshake.

NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

```csharp
server.Config("SSLNegotiatedCipher[connId]");
```

**SSLNegotiatedCipherStrength**: Returns the negotiated cipher suite strength.This configuration setting returns the strength of the cipher suite negotiated during the SSL handshake.

NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

```csharp
server.Config("SSLNegotiatedCipherStrength[connId]");
```

**SSLNegotiatedCipherSuite**: Returns the negotiated cipher suite.This configuration setting returns the cipher suite negotiated during the SSL handshake represented as a single string.

NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

```csharp
server.Config("SSLNegotiatedCipherSuite[connId]");
```

**SSLNegotiatedKeyExchange**: Returns the negotiated key exchange algorithm.This configuration setting returns the key exchange algorithm negotiated during the SSL handshake.

NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

```csharp
server.Config("SSLNegotiatedKeyExchange[connId]");
```

**SSLNegotiatedKeyExchangeStrength**: Returns the negotiated key exchange algorithm strength.This configuration setting returns the strength of the key exchange algorithm negotiated during the SSL handshake.

NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

```csharp
server.Config("SSLNegotiatedKeyExchangeStrength[connId]");
```

**SSLNegotiatedVersion**: Returns the negotiated protocol version.This configuration setting returns the protocol version negotiated during the SSL handshake.

NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

```csharp
server.Config("SSLNegotiatedVersion[connId]");
```

**SSLSecurityFlags**: Flags that control certificate verification.The following flags are defined (specified in hexadecimal notation). They can be ORed together to exclude multiple conditions:

|  |  |
| --- | --- |
| 0x00000001 | Ignore time validity status of certificate. |
| 0x00000002 | Ignore time validity status of CTL. |
| 0x00000004 | Ignore non-nested certificate times. |
| 0x00000010 | Allow unknown certificate authority. |
| 0x00000020 | Ignore wrong certificate usage. |
| 0x00000100 | Ignore unknown certificate revocation status. |
| 0x00000200 | Ignore unknown CTL signer revocation status. |
| 0x00000400 | Ignore unknown certificate authority revocation status. |
| 0x00000800 | Ignore unknown root revocation status. |
| 0x00008000 | Allow test root certificate. |
| 0x00004000 | Trust test root certificate. |
| 0x80000000 | Ignore non-matching CN (certificate CN non-matching server name). |

This functionality is currently not available when the provider is OpenSSL.

**SSLServerCACerts**: A newline separated list of CA certificates to use during SSL server certificate validation.This configuration setting is only used by client components (e.g., TCPClient) see [SSLClientCACerts](#SSLClientCACerts) for server components (e.g., TCPServer). This configuration setting can be used to optionally specify one or more CA certificates to be used when connecting to the server and verifying the server certificate. When verifying the server's certificate, the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

```text
-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----

... Root Cert...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----
```

**TLS12SignatureAlgorithms**: Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.This configuration setting specifies the allowed server certificate signature algorithms when [SSLProvider](#sslprovider-property-sharefile-class) is set to *Internal* and [SSLEnabledProtocols](#SSLEnabledProtocols) is set to allow TLS 1.2.

When specified the class will verify that the server certificate signature algorithm is among the values specified in this configuration setting. If the server certificate signature algorithm is unsupported, the class fails with an error.

The format of this value is a comma-separated list of hash-signature combinations. For instance:

```csharp
component.SSLProvider = TCPClientSSLProviders.sslpInternal;
component.Config("SSLEnabledProtocols=3072"); //TLS 1.2
component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa");
```

 The default value for this configuration setting is *sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa*.

To not restrict the server's certificate signature algorithm, specify an empty string as the value for this configuration setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

**TLS12SupportedGroups**: The supported groups for ECC.This configuration setting specifies a comma-separated list of named groups used in TLS 1.2 for ECC.

The default value is *ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1*.

When using TLS 1.2 and [SSLProvider](#sslprovider-property-sharefile-class) is set to *Internal*, the values refer to the supported groups for ECC. The following values are supported:

- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1" (default)

**TLS13KeyShareGroups**: The groups for which to pregenerate key shares.This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional roundtrip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result, only some groups are included by default in this configuration setting.

NOTE: All supported groups can always be used during the handshake even if not listed here, but if a group is used that is not present in this list, it will incur an additional roundtrip and time to generate the key share for that group.

In most cases, this configuration setting does not need to be modified. This should be modified only if there is a specific reason to do so.

The default value is *ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072*

The values are ordered from most preferred to least preferred. The following values are supported:

- "ecdhe_x25519" (default)
- "ecdhe_x448"
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1"
- "ffdhe_2048" (default)
- "ffdhe_3072" (default)
- "ffdhe_4096"
- "ffdhe_6144"
- "ffdhe_8192"

**TLS13SignatureAlgorithms**: The allowed certificate signature algorithms.This configuration setting holds a comma-separated list of allowed signature algorithms. Possible values include the following:

- "ed25519" (default)
- "ed448" (default)
- "ecdsa_secp256r1_sha256" (default)
- "ecdsa_secp384r1_sha384" (default)
- "ecdsa_secp521r1_sha512" (default)
- "rsa_pkcs1_sha256" (default)
- "rsa_pkcs1_sha384" (default)
- "rsa_pkcs1_sha512" (default)
- "rsa_pss_sha256" (default)
- "rsa_pss_sha384" (default)
- "rsa_pss_sha512" (default)

 The default value is *rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448*. This configuration setting is applicable only when [SSLEnabledProtocols](#SSLEnabledProtocols) includes TLS 1.3.

**TLS13SupportedGroups**: The supported groups for (EC)DHE key exchange.This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. This configuration setting should be modified only if there is a specific reason to do so.

The default value is *ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192,mlkem_512,mlkem_768,mlkem_1024,x25519_mlkem_768,secp256r1_mlkem_768*

The values are ordered from most preferred to least preferred. The following values are supported:

- "ecdhe_x25519" (default)
- "ecdhe_x448" (default)
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1" (default)
- "ffdhe_2048" (default)
- "ffdhe_3072" (default)
- "ffdhe_4096" (default)

- "mlkem_1024" (default)
- "x25519_mlkem_768" (default)
- "secp256r1_mlkem_768" (default)

Post-quantum algorithms (*mlkem_512,mlkem_768,mlkem_1024,x25519_mlkem_768,secp256r1_mlkem_768*) in our components rely on the operating system's underlying cryptographic primitives. The following platforms are currently supported:

-  Windows Server 2025
-  Windows 11 24H2
-  Windows 11 25H2

### Socket Config Settings

**AbsoluteTimeout**: Determines whether timeouts are inactivity timeouts or absolute timeouts.If [AbsoluteTimeout](#AbsoluteTimeout) is set to True, any method that does not complete within [Timeout](#timeout-property-sharefile-class) seconds will be aborted. By default, *AbsoluteTimeout* is False, and the timeout is an inactivity timeout.

NOTE: This option is not valid for User Datagram Protocol (UDP) ports.

**FirewallData**: Used to send extra data to the firewall.When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g., headers for custom authentication schemes).

**InBufferSize**: The size in bytes of the incoming queue of the socket.This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the *InBufferSize* setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the *InBufferSize* reverts to its defined size. The same happens if you attempt to make it too large or too small.

**OutBufferSize**: The size in bytes of the outgoing queue of the socket.This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. In some cases, increasing the value of the *OutBufferSize* setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the *OutBufferSize* reverts to its defined size. The same happens if you attempt to make it too large or too small.

### Base Config Settings

**BuildInfo**: Information about the product's build.When queried, this setting will return a string containing information about the product's build.

**CodePage**: The system code page used for Unicode to Multibyte translations.The default code page is Unicode UTF-8 (65001).

**LicenseInfo**: Information about the current license.When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

- Product: The product the license is for.
- Product Key: The key the license was generated from.
- License Source: Where the license was found (e.g., RuntimeLicense, License File).
- License Type: The type of license installed (e.g., Royalty Free, Single Server).
- Last Valid Build: The last valid build number for which the license will work.

**MaskSensitiveData**: Whether sensitive data is masked in log messages.In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to *true* to mask sensitive data. The default is *true*.

**ProcessIdleEvents**: Whether the class uses its internal event loop to process events when the main thread is idle.If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

**SelectWaitMillis**: The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.If there are no events to process when DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20.

**UseFIPSCompliantAPI**: Tells the class whether or not to use FIPS certified APIs.When set to *true*, the class will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle Federal Information Processing Standards (FIPS), while all other Windows editions make use of Microsoft security libraries.

FIPS mode can be enabled by setting the *UseFIPSCompliantAPI* configuration setting to *true*. This is a static setting that applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.

For more details, please see the [FIPS 140-2 Compliance](https://www.nsoftware.com/kb/articles/fips.rst) article.

NOTE: This setting is applicable only on Windows.

NOTE: Enabling FIPS compliance requires a special license; please contact [sales@nsoftware.com](mailto:sales@nsoftware.com) for details.

**UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *false*, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to *true* tells the class to use the internal implementation instead of using the system security libraries.

 On Windows, this setting is set to *false* by default. On Linux/macOS, this setting is set to *true* by default.

 To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the [OpenSSL Notes](platforms.md) section.

# Trappable Errors ([ShareFile](#sharefile-class) Class)

## Error Handling (C++)

Call the *GetLastErrorCode()* method to obtain the last called method's result code; *0* indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the *GetLastError()* method can be called to retrieve the associated error message.
