The GoogleStorage class implements the Google Storage for Developers API.

Syntax

GoogleStorage

Remarks

GoogleStorage allows you to easily manage storing and retrieving files using the Google Storage for Developers service.

Before using the class you must have a valid Google Storage account.

Authentication

This class requires authentication via OAuth 2.0. First, perform OAuth authentication using the OAuth* properties to set the appropriate fields for the chosen OAuthClientProfile and OAuthGrantType.

The class has the following defaults:

Authorization Server URL "https://accounts.google.com/o/oauth2/auth"
Token Server URL "https://accounts.google.com/o/oauth2/token"
Scopes "https://www.googleapis.com/auth/cloud-platform"

Below is a brief description of the different OAuthClientProfile and OAuthGrantType 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 method should be called. If the authorization and authentication was successful, then the OAuthAccessToken property will be populated. Additionally, if a refresh token was provided the OAuthRefreshToken property 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 OAuthAccessToken will be expired. When a method that makes requests to the service provider is called or the Authorize 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 OAuthAccessToken. If the Authorize 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 OAuthGrantType property. To force the component to only check the access token when the Authorize method is called, the OAuthAutomaticRefresh configuration setting can be set to false.

A brief description of the supported values for the OAuthGrantType property 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 OAuthGrantType the class expects a OAuthClientId, OAuthClientSecret, OAuthServerAuthURL, and OAuthServerTokenURL to be set. When the Authorize 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 OAuthAuthorizationCode property, 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 OAuthRefreshToken property 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.

Example: GoogleStorage googlestorage = new GoogleStorage(); googlestorage.OAuth.ClientProfile = OAuthClientProfiles.cocpApplication; googlestorage.OAuth.GrantType = OAuthGrantTypes.cogtAuthorizationCode; googlestorage.OAuth.ClientId = CLIENT_ID; googlestorage.OAuth.ClientSecret = CLIENT_SECRET; googlestorage.Authorize();

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 OAuthGrantType the class expects a OAuthClientId, OAuthClientSecret, and OAuthServerAuthURL to be set. When the Authorize 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.

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 OAuthClientId, OAuthClientSecret, OAuthServerAuthURL, OAuthServerTokenURL, and the OAuthReturnURL properties to be set. Before calling the Authorize method, the OAuthWebAuthURL property 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 OAuthReturnURL property. The OAuthReturnURL property 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 OAuthAuthorizationCode property. Once that is set, the Authorize 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 OAuthRefreshToken field is set, or a refresh token is cached, then the Authorize 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 the OAuth class or a separate process. Once complete you should have an authorization string which looks like:
Bearer ACCESS_TOKEN_VALUE

Assign this value to the Authorization property before attempting any operations. Setting the Authorization property will cause the class to ignore the values set in the OAuth property.

For Example: Oauth oauth = new Oauth(); oauth.ClientId = "CLIENT_ID"; oauth.ClientSecret = "CLIENT_SECRET"; oauth.AuthorizationScope = "https://www.googleapis.com/auth/cloud-platform"; oauth.ServerAuthURL = "https://accounts.google.com/o/oauth2/auth"; oauth.ServerTokenURL = "https://accounts.google.com/o/oauth2/token"; oauth.GrantType = OauthGrantTypes.ogtAuthorizationCode; googlestorage.Authorization = oauth.GetAuthorization(); Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.

Once you have a valid Google Storage account you can start creating buckets in your account using CreateBucket. The buckets are place holders for your objects allowing you to access them by http URLs. You can then add objects to any of your buckets using CreateObject.

There are other methods such as ListBuckets, ListObjects, GetObject, DeleteObject etc. that further enable you to manage your Google Storage data store.

When authenticating via OAuth the ProjectId property is also required.

Alternatively, this service also supports authenticating by setting the AccessKey and SecretKey configuration settings.

Remarks

This is the name of the certificate store for the client certificate.

The SSLCertStoreType property denotes the type of the certificate store specified by SSLCertStore. If the store is password protected, specify the password in SSLCertStorePassword.

SSLCertStore is used in conjunction with the SSLCertSubject property to specify client certificates. If SSLCertStore has a value, and SSLCertSubject or SSLCertEncoded is set, a search for a certificate is initiated. Please see the SSLCertSubject property for details.

Designations of certificate stores are platform-dependent.

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

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

int SetSSLCertStoreType(int iSSLCertStoreType);

Default Value

0

Remarks

This is 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 property can take one of the following values:

0 (cstUser - 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 (cstMachine)For Windows, this specifies that the certificate store is a machine store. Note: this store type is not available in Java.
2 (cstPFXFile)The certificate store is the name of a PFX (PKCS12) file containing certificates.
3 (cstPFXBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in PFX (PKCS12) format.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: this store type is only available in Java.
5 (cstJKSBlob)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 only available in Java.
6 (cstPEMKeyFile)The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)The certificate store is a string (binary or base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)The certificate store is a string (binary or base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)The certificate store is a string (binary or base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)The certificate store is the name of a PKCS7 file containing certificates.
12 (cstP7BBlob)The certificate store is a string (binary) representing a certificate store in PKCS7 format.
13 (cstSSHPublicKeyFile)The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 (cstXMLFile)The certificate store is the name of a file that contains a certificate in XML format.
17 (cstXMLBlob)The certificate store is a string that contains a certificate in XML format.
18 (cstJWKFile)The certificate store is the name of a file that contains a JWK (JSON Web Key).
19 (cstJWKBlob)The certificate store is a string that contains a JWK (JSON Web Key).
21 (cstBCFKSFile)The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store). Note: this store type is only available in Java and .NET.
22 (cstBCFKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: this store type is only available in Java and .NET.
23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS11 interface.

To use a security key the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the SSLCertStore and set SSLCertStorePassword to the PIN.

Code Example: SSH Authentication with Security Key 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);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

Data Type

Integer

SSLCertSubject Property (GoogleStorage Class)

This is the subject of the certificate used for client authentication.

Syntax

ANSI (Cross Platform)
char* GetSSLCertSubject();
int SetSSLCertSubject(const char* lpszSSLCertSubject); Unicode (Windows) LPWSTR GetSSLCertSubject();
INT SetSSLCertSubject(LPCWSTR lpszSSLCertSubject);
char* cloudstorage_googlestorage_getsslcertsubject(void* lpObj);
int cloudstorage_googlestorage_setsslcertsubject(void* lpObj, const char* lpszSSLCertSubject);
QString GetSSLCertSubject();
int SetSSLCertSubject(QString qsSSLCertSubject);

Default Value

""

Remarks

This is 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 property 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=support@nsoftware.com". Common fields and their meanings are displayed below.

FieldMeaning
CNCommon Name. This is commonly a host name like www.server.com.
OOrganization
OUOrganizational Unit
LLocality
SState
CCountry
EEmail Address

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

Data Type

SSLProvider Property (GoogleStorage Class)

This specifies the SSL/TLS implementation to use.

Syntax

ANSI (Cross Platform)
int GetSSLProvider();
int SetSSLProvider(int iSSLProvider); Unicode (Windows) INT GetSSLProvider();
INT SetSSLProvider(INT iSSLProvider);

Possible Values

SSLP_AUTOMATIC(0), 
SSLP_PLATFORM(1),
SSLP_INTERNAL(2)
int cloudstorage_googlestorage_getsslprovider(void* lpObj);
int cloudstorage_googlestorage_setsslprovider(void* lpObj, int iSSLProvider);
int GetSSLProvider();
int SetSSLProvider(int iSSLProvider);

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:

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 the internal implementation is used on all platforms.

Data Type

Integer

SSLServerCertEncoded Property (GoogleStorage Class)

This is the certificate (PEM/base64 encoded).

Syntax

ANSI (Cross Platform)
int GetSSLServerCertEncoded(char* &lpSSLServerCertEncoded, int &lenSSLServerCertEncoded);

Unicode (Windows)
INT GetSSLServerCertEncoded(LPSTR &lpSSLServerCertEncoded, INT &lenSSLServerCertEncoded);
int cloudstorage_googlestorage_getsslservercertencoded(void* lpObj, char** lpSSLServerCertEncoded, int* lenSSLServerCertEncoded);
QByteArray GetSSLServerCertEncoded();

Default Value

""

Remarks

This is the certificate (PEM/base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.

When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.

This property is read-only and not available at design time.

int cloudstorage_googlestorage_gettimeout(void* lpObj);
int cloudstorage_googlestorage_settimeout(void* lpObj, int iTimeout);
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.

Please note that by default, all timeouts are inactivity timeouts, i.e. 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

Unicode (Windows)
INT AddMetadata(LPCWSTR lpszName, LPCWSTR lpszValue);
int cloudstorage_googlestorage_addmetadata(void* lpObj, const char* lpszName, const char* lpszValue);
int AddMetadata(const QString& qsName, const QString& qsValue);

Remarks

This method adds a metadata item to the Metadata* properties. Name specifies the name of the item, and Value specifies the value of the item. Keep in mind that the server stores metadata names in lowercase.

If Name begins with a service-specific metadata (e.g., x-amz-meta-, x-goog-meta-, etc.), it will be stripped off. The class will take care of prepending it when sending metadata to the server.

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.)

AddQueryParam Method (GoogleStorage Class)

Adds a query parameter to the QueryParams properties.

Syntax

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

All specified Values 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 (GoogleStorage Class)

Get the authorization string required to access the protected resource.

Syntax

ANSI (Cross Platform)
int Authorize();

Unicode (Windows)
INT Authorize();
int cloudstorage_googlestorage_authorize(void* lpObj);
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 OAuthClientProfile property and the OAuthGrantType property. This method is not to be used in conjunction with the Authorization property. It should instead be used when setting the OAuth* properties.

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. 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.)

int BucketExists();

Unicode (Windows)
INT BucketExists();
int cloudstorage_googlestorage_bucketexists(void* lpObj);
bool BucketExists();

Remarks

This method checks whether the bucket specified by Bucket exists, returning true if so or false if not.

Error Handling (C++)

This method returns a Boolean 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.

CalcAuthorization Method (GoogleStorage Class)

Calculates the Authorization header based on provided credentials.

Syntax

ANSI (Cross Platform)
int CalcAuthorization();

Unicode (Windows)
INT CalcAuthorization();
int cloudstorage_googlestorage_calcauthorization(void* lpObj);
int CalcAuthorization();

Remarks

This method calculates the Authorization value using the values provided in AuthScheme, User and Password.

In most cases this method does not need to be called. The class will automatically calculate any required authorization values when a method is called such as Get or Post.

This method may be useful in cases where the Authorization value needs to be calculated prior to sending a request.

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.)

CheckVersioningEnabled Method (GoogleStorage Class)

Checks whether versioning is enabled for the currently selected bucket.

Syntax

ANSI (Cross Platform)
int CheckVersioningEnabled();

Unicode (Windows)
INT CheckVersioningEnabled();
int cloudstorage_googlestorage_checkversioningenabled(void* lpObj);
bool CheckVersioningEnabled();

Remarks

This method can be used to check whether the bucket currently selected by Bucket has versioning enabled.

Note that if Bucket is empty, or refers to a bucket that does not exist, this method will always return false when queried.

Refer to Amazon's Versioning documentation for more information about versioning.

Error Handling (C++)

This method returns a Boolean 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.

ComposeObjects Method (GoogleStorage Class)

Creates a composed object using multiple objects already on the server.

Syntax

ANSI (Cross Platform)
int ComposeObjects(const char* lpszComposedObjectName);

Unicode (Windows)
INT ComposeObjects(LPCWSTR lpszComposedObjectName);
int cloudstorage_googlestorage_composeobjects(void* lpObj, const char* lpszComposedObjectName);
int ComposeObjects(const QString& qsComposedObjectName);

Remarks

This method is used to compose objects on the server. Object composition is a server-side method of building an object by concatenating multiple existing objects together. This feature is a simpler alternative to the typical multipart-upload method of building objects.

A composed object looks and acts just like a regular object. However, its data is determined by its component objects (that is, the objects that make it up) and the order in which they are composed together.

To use this method, specify the names of the objects that should be composed together using the Objects property. When this method is called, the ComposedObjectName parameter determines what name is given to the resulting composed object. See the following code snippet for examples: // Upload some objects to start with. Let's assume we have some text files to upload. for (int i = 1; i <= 3; i++) { gstorage.LocalFile = "file" + i + ".txt"; gstorage.CreateObject("file" + i + ".txt"); } // Compose a new object. SetObjectNames("file1.txt", "file2.txt", "file3.txt"); gstorage.ComposeObjects("composed1.txt"); // Compose a new object using a composed object. SetObjectNames("file1.txt", "composed1.txt"); gstorage.ComposeObjects("composed2.txt"); // Compose onto an existing composed object. // (Similar to appending, but all server-side, no uploading needed.) SetObjectNames("file1.txt", "file2.txt"); gstorage.ComposeObjects("composed3.txt"); SetObjectNames("composed3.txt", "file3.txt"); gstorage.ComposeObjects("composed3.txt"); // Compose a new object using the same object twice. SetObjectNames("file1.txt", "file1.txt"); gstorage.ComposeObjects("composed4.txt"); // Compose a composed object onto itself. SetObjectNames("composed4.txt", "composed4.txt"); gstorage.ComposeObjects("composed4.txt"); Assume we have this helper method for the above code: void SetObjectNames(params string[] names) { gstorage.Objects.Clear(); foreach (string name in names) gstorage.Objects.Add(new S3Object(name, "", 0, "", "", "", "", "")); }

Object composition is a powerful and flexible feature. However, there are some things to keep in mind when doing object composition:

  • The order of the object names in the Objects property is the order that they will be concatenated in when they are composed.
  • Objects from multiple buckets cannot be composed together.
  • No more than 32 object names may be specified in a single compose request.

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.)

Config Method (GoogleStorage Class)

Sets or retrieves a configuration setting.

Syntax

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

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);
char* cloudstorage_googlestorage_config(void* lpObj, const char* lpszConfigurationString);
QString Config(const QString& qsConfigurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings 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, 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.

CopyObject Method (GoogleStorage Class)

Copies an object.

Syntax

ANSI (Cross Platform)
int CopyObject(const char* lpszSrcObjectName, const char* lpszDestBucket, const char* lpszDestObjectName);

Unicode (Windows)

int cloudstorage_googlestorage_copyobject(void* lpObj, const char* lpszSrcObjectName, const char* lpszDestBucket, const char* lpszDestObjectName);
int CopyObject(const QString& qsSrcObjectName, const QString& qsDestBucket, const QString& qsDestObjectName);

Remarks

This method copies the object specified by SrcObjectName (in the bucket currently selected by Bucket) to the object specified by DestObjectName in DestBucket. If DestBucket is empty, the bucket specified by Bucket is used as the destination bucket.

If the VersionId property is non-empty, the specified version of the source object will be used as the copy source. In this case, DestObjectName may be the same as SrcObjectName to "promote" the version, copying its contents back to the base object.

If there are any metadata items present in the Metadata* properties, they will set on the destination object; otherwise, the server will copy any metadata items present on the source object to the destination object.

Notes:

  • Objects may only be copied to buckets that exist within the same region.
  • Objects larger than 5GB cannot be copied using this method. To copy such objects, start a new multipart upload for the destination object using StartMultipartUpload, and then use the CopyPart method to create parts for said multipart upload using the source object's data.

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.)

CreateBucket Method (GoogleStorage Class)

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.)

CreateObject Method (GoogleStorage Class)

Creates a new object in the currently selected bucket.

Syntax

ANSI (Cross Platform)
int CreateObject(const char* lpszObjectName);

Unicode (Windows)
INT CreateObject(LPCWSTR lpszObjectName);
int cloudstorage_googlestorage_createobject(void* lpObj, const char* lpszObjectName);
int CreateObject(const QString& qsObjectName);

Remarks

This method creates a new object named Object in the bucket currently selected by Bucket. If there are any metadata items present in the Metadata* properties, they will included in the creation request.

If SetUploadStream has been used to set an upload stream, it will take priority as the data source. If LocalFile is set the file will be uploaded from the specified path. If LocalFile is not set the data in ObjectData will be used.

To encrypt the file before uploading it, set EncryptionAlgorithm and EncryptionPassword.

This method can automatically handle the multipart upload of objects (See Below). If it is desired to manually take control of the multipart upload process see StartMultipartUpload.

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.

ANSI (Cross Platform)
int DoEvents();

Unicode (Windows)
INT DoEvents();
int cloudstorage_googlestorage_doevents(void* lpObj);
int DoEvents();

Remarks

When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

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.)

If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

GetObject Method (GoogleStorage Class)

Downloads an object.

Syntax

ANSI (Cross Platform)
int GetObject(const char* lpszObjectName);

Unicode (Windows)
INT GetObject(LPCWSTR lpszObjectName);
int cloudstorage_googlestorage_getobject(void* lpObj, const char* lpszObjectName);
int GetObject(const QString& qsObjectName);

Remarks

This methods downloads the object specified by ObjectName in the bucket currently selected by Bucket. If the VersionId property is non-empty, the specified version of the object is downloaded instead. The Range property can be used to download a specific range of bytes from the object.

If a stream has been specified using SetDownloadStream, the object data will be sent through it. If a stream is not specified, and LocalFile is set, the object data will be saved to the specified location; otherwise, the object data will be held by ObjectData.

To download and decrypt an encrypted object, set EncryptionAlgorithm and EncryptionPassword before calling this method.

Download Notes

In the simplest use-case, downloading an object looks like this: s3.LocalFile = "../MyData.zip"; s3.GetObject(s3.Objects[0].Name);

Resuming Downloads

The class also supports resuming failed downloads by using the StartByte property. If a download is interrupted, set StartByte to the appropriate offset before calling this method to resume the download. string downloadFile = "../MyData.zip"; s3.LocalFile = downloadFile; s3.GetObject(s3.Objects[0].Name); //The transfer is interrupted and GetObject() above fails. Later, resume the download: //Get the size of the partially downloaded file s3.StartByte = new FileInfo(downloadFile).Length; s3.GetObject(s3.Objects[0].Name);

Resuming Encrypted File Downloads

Resuming encrypted file downloads is only supported when LocalFile was set in the initial download attempt.

If LocalFile is set when beginning an encrypted download, the class creates a temporary file in TempPath to hold the encrypted data until the download is complete. If the download is interrupted, DownloadTempFile will be populated with the path of the temporary file that holds the partial data.

To resume, DownloadTempFile must be populated, along with StartByte, to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to LocalFile. s3.LocalFile = "../MyData.zip"; s3.EncryptionPassword = "password"; s3.GetObject(s3.Objects[0].Name); //The transfer is interrupted and GetObject() above fails. Later, resume the download: //Get the size of the partially downloaded temp file s3.StartByte = new FileInfo(s3.Config("DownloadTempFile")).Length; s3.GetObject(s3.Objects[0].Name);

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.)

Unicode (Windows)
INT GetObjectInfo(LPCWSTR lpszObjectName);
int cloudstorage_googlestorage_getobjectinfo(void* lpObj, const char* lpszObjectName);
int GetObjectInfo(const QString& qsObjectName);

Remarks

This method gets information and metadata for the object specified by Object in the bucket currently selected by Bucket. If the VersionId property is non-empty, information and metadata for the specified version of the object is retrieved instead.

Calling this method will fire the ObjectList and MetadataList events, and will re-populate the Objects* and Metadata* properties.

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.)

Interrupt Method (GoogleStorage Class)

ListObjects Method (GoogleStorage Class)

Lists the objects in a bucket.

Syntax

ANSI (Cross Platform)
int ListObjects();

Unicode (Windows)
INT ListObjects();
int cloudstorage_googlestorage_listobjects(void* lpObj);
int ListObjects();

Remarks

This method lists the objects in the bucket currently selected by Bucket.

Before calling this method, the ObjectPrefix property may be set in order to restrict the results to only the objects whose names begin with a given string. The ObjectDelimiter property can also be used to further tune the results returned. The MaxObjects configuration setting may be used to limit the number of results returned.

Calling this method will fire the ObjectList event once for each object, and will also populate the Objects* properties. It may also fire the PrefixList event, and populate the PrefixCount and Prefix[i] configuration settings, depending on how the properties discussed above are set.

If there are still more objects available to list when this method returns, the ObjectMarker property will be populated. Continue to call this method until ObjectMarker is empty to accumulate all pages of results in the Objects* properties.

Object Hierarchy Traversal

By using the ObjectDelimiter and ObjectPrefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:

  • MyCompany/
  • MyCompany/Department1/
  • MyCompany/Department2/
  • MyCompany/Department2/EmployeeA
  • MyCompany/Department2/EmployeeB

With ObjectDelimiter set to /, we can set ObjectPrefix to successively "deeper" values before calling ListObjects or ListVersions for the following effect:

ObjectPrefix Value ObjectDelimiter Value Objects Returned Prefixes Returned
(empty) /(none) MyCompany/
MyCompany/ /MyCompany/ MyCompany/Department1/

MyCompany/Department2/

MyCompany/Department2/ /MyCompany/Department2/

MyCompany/Department2/EmployeeA

MyCompany/Department2/EmployeeB

(none)

Error Handling (C++)

Valid values for HttpMethod are:

  • GET (default if empty)
  • HEAD
  • POST
  • PUT
  • DELETE

The ObjectName and RequestBody parameters may be empty if not needed.

Usage

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

  1. Builds a request URL, including query parameters, based on the following:
    • UseSSL, Region, and UseVirtualHosting for the base URL.
      • Alternatively, if a custom URL has been specified using the URL configuration setting, it is used directly, and these properties are ignored.
    • Bucket (if non-empty)
    • ObjectName (if non-empty)
    • VersionId (if both it and ObjectName are non-empty)
    • QueryParam*
  2. Adds request headers from:
  3. Signs the request (unless the SignCustomRequest configuration setting is disabled).
  4. Sends the request, including RequestBody if non-empty.
  5. Stores the response headers in the ParsedHeader* properties; and the response body in the stream specified using SetDownloadStream, the specified LocalFile, or ObjectData (using the same logic as GetObject).

If the response body is XML data, the XPath, 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.

INT SetDownloadStream(CloudStorageStream* sDownloadStream);
int cloudstorage_googlestorage_setdownloadstream(void* lpObj, CloudStorageStream* sDownloadStream);
int SetDownloadStream(CloudStorageStream* sDownloadStream);

Remarks

If a download stream is set before data is downloaded, the downloaded data will be written to the stream. The stream should be open and normally set to position 0.

Note: Passing a non-null value for DownloadStream will cause LocalFile to be cleared. Similarly, setting LocalFile to a non-empty value will discard any stream set using this method.

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.

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"

};
// To handle, connect one or more slots to this signal. void ObjectList(GoogleStorageObjectListEventParams *e);
// Or, subclass GoogleStorage and override this emitter function. virtual int FireObjectList(GoogleStorageObjectListEventParams *e) {...}

Remarks

This event fires once for each object, or object version, returned when GetObjectInfo, ListObjects, or ListVersions is called.

BucketName reflects the name of the bucket that the object is in.

ObjectName reflects the name of the object.

LastModified reflects the last modified time of the object.

Size reflects the size, in bytes, of the object.

ETag reflects the object's ETag.

OwnerId and OwnerName reflect the Id and display name of the object's owner, respectively. Not applicable when GetObjectInfo is called.

VersionId reflects the Id of the object version (note that the string null is a valid version Id). Only applicable when ListVersions is called, or when GetObjectInfo is called while VersionId is non-empty; empty in all other cases.

LatestVersion indicates whether this is the latest object version. Only applicable when ListVersions is called; true in all other cases.

Deleted indicates whether this object version was deleted or overwritten. Only applicable when ListVersions is called; false in all other cases.

PrefixList Event (GoogleStorage Class)

Fires once for each common prefix returned when listing objects.

Syntax

ANSI (Cross Platform)
virtual int FirePrefixList(GoogleStoragePrefixListEventParams *e);
typedef struct {
const char *BucketName;
const char *Prefix; int reserved; } GoogleStoragePrefixListEventParams;
Unicode (Windows) virtual INT FirePrefixList(GoogleStoragePrefixListEventParams *e);

// Or, subclass GoogleStorage and override this emitter function. virtual int FirePrefixList(GoogleStoragePrefixListEventParams *e) {...}

Remarks

This event fires once for each common prefix returned when ListObjects or ListVersions is called when ObjectDelimiter is non-empty. Refer to ObjectDelimiter for more information.

BucketName reflects the name of the bucket that the prefix is in.

Prefix is the common prefix.

Progress Event (GoogleStorage Class)

Fires during an upload or download to indicate transfer progress.

Syntax

ANSI (Cross Platform)
virtual int FireProgress(GoogleStorageProgressEventParams *e);
typedef struct {
int Direction;
int64 BytesTransferred;
int64 TotalBytes;
int PercentDone; int reserved; } GoogleStorageProgressEventParams;
Unicode (Windows) virtual INT FireProgress(GoogleStorageProgressEventParams *e);
typedef struct {
INT Direction;
LONG64 BytesTransferred;
LONG64 TotalBytes;
INT PercentDone; INT reserved; } GoogleStorageProgressEventParams;
#define EID_GOOGLESTORAGE_PROGRESS 9

virtual INT CLOUDSTORAGE_CALL FireProgress(INT &iDirection, LONG64 &lBytesTransferred, LONG64 &lTotalBytes, INT &iPercentDone);
class GoogleStorageProgressEventParams {
public:
  int Direction();

  qint64 BytesTransferred();

  qint64 TotalBytes();

  int PercentDone();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Progress(GoogleStorageProgressEventParams *e);
// Or, subclass GoogleStorage and override this emitter function. virtual int FireProgress(GoogleStorageProgressEventParams *e) {...}

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 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 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 (GoogleStorage Class)

Fired after the server presents its certificate to the client.

Syntax

ANSI (Cross Platform)
virtual int FireSSLServerAuthentication(GoogleStorageSSLServerAuthenticationEventParams *e);
typedef struct {
const char *CertEncoded; int lenCertEncoded;
const char *CertSubject;
const char *CertIssuer;
const char *Status;
int Accept; int reserved; } GoogleStorageSSLServerAuthenticationEventParams;
Unicode (Windows) virtual INT FireSSLServerAuthentication(GoogleStorageSSLServerAuthenticationEventParams *e);
typedef struct {
LPCSTR CertEncoded; INT lenCertEncoded;
LPCWSTR CertSubject;
LPCWSTR CertIssuer;
LPCWSTR Status;
BOOL Accept; INT reserved; } GoogleStorageSSLServerAuthenticationEventParams;
#define EID_GOOGLESTORAGE_SSLSERVERAUTHENTICATION 10

virtual INT CLOUDSTORAGE_CALL FireSSLServerAuthentication(LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);
class GoogleStorageSSLServerAuthenticationEventParams {
public:
  const QByteArray &CertEncoded();

  const QString &CertSubject();

  const QString &CertIssuer();

  const QString &Status();

  bool Accept();
  void SetAccept(bool bAccept);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void SSLServerAuthentication(GoogleStorageSSLServerAuthenticationEventParams *e);
// Or, subclass GoogleStorage and override this emitter function. virtual int FireSSLServerAuthentication(GoogleStorageSSLServerAuthenticationEventParams *e) {...}

Remarks

This event is where the client can decide whether to continue with the connection process or not. 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 to continue or not.

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 (GoogleStorage Class)

Shows the progress of the secure connection.

Syntax

ANSI (Cross Platform)
virtual int FireSSLStatus(GoogleStorageSSLStatusEventParams *e);
typedef struct {
const char *Message; int reserved; } GoogleStorageSSLStatusEventParams;
Unicode (Windows) virtual INT FireSSLStatus(GoogleStorageSSLStatusEventParams *e);
typedef struct {
LPCWSTR Message; INT reserved; } GoogleStorageSSLStatusEventParams;
#define EID_GOOGLESTORAGE_SSLSTATUS 11

virtual INT CLOUDSTORAGE_CALL FireSSLStatus(LPSTR &lpszMessage);
class GoogleStorageSSLStatusEventParams {
public:

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void SSLStatus(GoogleStorageSSLStatusEventParams *e);
// Or, subclass GoogleStorage and override this emitter function. virtual int FireSSLStatus(GoogleStorageSSLStatusEventParams *e) {...}

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

StartTransfer Event (GoogleStorage Class)

This event fires when a document starts transferring (after the headers).

Syntax

ANSI (Cross Platform)
virtual int FireStartTransfer(GoogleStorageStartTransferEventParams *e);
typedef struct {
int Direction; int reserved; } GoogleStorageStartTransferEventParams;
Unicode (Windows) virtual INT FireStartTransfer(GoogleStorageStartTransferEventParams *e);
typedef struct {
INT Direction; INT reserved; } GoogleStorageStartTransferEventParams;
#define EID_GOOGLESTORAGE_STARTTRANSFER 12

virtual INT CLOUDSTORAGE_CALL FireStartTransfer(INT &iDirection);
class GoogleStorageStartTransferEventParams {
public:

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void StartTransfer(GoogleStorageStartTransferEventParams *e);
// Or, subclass GoogleStorage and override this emitter function. virtual int FireStartTransfer(GoogleStorageStartTransferEventParams *e) {...}

Remarks

The StartTransfer event is fired 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 (GoogleStorage Class)

This event is fired while a document transfers (delivers document).

Syntax

ANSI (Cross Platform)
virtual int FireTransfer(GoogleStorageTransferEventParams *e);
typedef struct {
int Direction;
int64 BytesTransferred;
int PercentDone;
const char *Text; int lenText; int reserved; } GoogleStorageTransferEventParams;
Unicode (Windows) virtual INT FireTransfer(GoogleStorageTransferEventParams *e);
typedef struct {
INT Direction;
LONG64 BytesTransferred;
INT PercentDone;
LPCSTR Text; INT lenText; INT reserved; } GoogleStorageTransferEventParams;
#define EID_GOOGLESTORAGE_TRANSFER 13

virtual INT CLOUDSTORAGE_CALL FireTransfer(INT &iDirection, LONG64 &lBytesTransferred, INT &iPercentDone, LPSTR &lpText, INT &lenText);
class GoogleStorageTransferEventParams {
public:
  int Direction();

  qint64 BytesTransferred();

  int PercentDone();

  const QByteArray &Text();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Transfer(GoogleStorageTransferEventParams *e);
// Or, subclass GoogleStorage and override this emitter function. virtual int FireTransfer(GoogleStorageTransferEventParams *e) {...}

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.

CloudStorageStream Type

Syntax

CloudStorageStream (declared in cloudstorage.h)

Remarks

The GoogleStorage 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 GoogleStorage 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.

Properties

CanRead Whether the stream supports reading.

bool CanRead() { return true; }
CanSeek Whether the stream supports seeking.

bool CanSeek() { return true; }
CanWrite Whether the stream supports writing.

bool CanWrite() { return true; }
Length Gets the length of the stream, in bytes.

int64 GetLength() = 0;

Methods

Close Closes the stream, releasing all resources currently allocated for it.

void Close() {}

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.

int Flush() { return 0; }

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.

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

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.

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

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.

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

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 (GoogleStorage 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 method.

GoogleStorage Config Settings

AccessKey:   The Access Key Id for the Google account.

This is the username for the Google account. No two accounts may have the same Access Key. This is used along with the SecretKey to authenticate with Google servers.

ContentRange:   This contains the range of bytes of the current object that are being returned.

When implementing chunked and resumable object downloads by setting the Range property, this configuration will contain the returned range of bytes and the total count of bytes for the specified object. This configuration will be populated after a call to GetObject

DownloadTempFile:   The temporary file used when downloading encrypted data.

This setting specifies the temporary file used when downloading encrypted data.

When downloading encrypted data with LocalFile set, the class will automatically create a temporary file at TempPath to hold the encrypted file contents. When the download is complete, the data is decrypted to LocalFile.

If the download is interrupted, the specified file will hold the partially downloaded encrypted file contents. Before resuming the download, this setting must be set to a valid file containing the partially encrypted file contents. See DownloadFile for details.

EncryptionIV:   The initialization vector to be used for encryption/decryption.

When encrypting or decrypting a file, this setting may be set to specify the initialization vector. Normally the class will derive this value automatically from EncryptionPassword.

This setting accepts a hex encoded value.

EncryptionKey:   The key to use during encryption/decryption.

When encrypting or decrypting a file, this setting may be set to specify the key to use. Normally the class will derive this value automatically from EncryptionPassword.

This setting accepts a hex encoded value.

EncryptionPasswordKDF:   The KDF algorithm to use during password based encryption and decryption.

This setting specified the Key Derivation Function (KDF) used to derive a key from the specified EncryptionPassword. Possible values are:

  • 0 (default) - PBKDF1
  • 1 - PBKDF2
Note: PBKDF1 is not FIPS compliant. When operating in FIPS mode PBKDF2 should be used.

EnforceBucketNameRestrictions:   Whether or not to enforce bucket naming conventions.

When set to false (default) the class will not enforce the bucket naming restrictions. US based buckets are not subject to the same name restrictions as other locations. When set to true the class will enforce the following restrictions:

  • Bucket names can contain lowercase letters, numbers, periods, underscores, and dashes.
  • Bucket names must start with a number or letter.
  • Bucket names must be between 3 and 63 characters long.
  • Bucket names should not end with a dash.
  • Bucket names cannot contain two adjacent periods.
  • Bucket names cannot contain dashes next to periods.
  • Bucket names must not be formatted as an IP address (eg: 192.168.5.4).
  • Bucket names cannot begin with "goog".
  • Bucket names cannot contain "google" or close misspellings, such as "g00gle".
ETag:   The ETag for the object returned by the server.

This contains the ETag for the object returned after GetObject is called.

When implementing chunked and resumable object downloads, the ETag is used to determine if the object has changed since the last chunk was downloaded. Set the IfMatch config to the ETag of the previous request to tell the class to make sure the object has not changed.

IfMatch:   Check to make sure the object has not been modified since the last request.

When implementing chunked and resumable object downloads, the IfMatch config is used to determine if the object has changed since the last chunk was downloaded. Set the IfMatch config to the ETag of the previous request to tell the class to make sure the object has not changed before a call to GetObject.

IncludeContentMD5:   Whether an MD5 digest of a custom request's data should be included.

If set to true, the class will include an MD5 digest of the RequestBody passed to SendCustomRequest when the request is submitted.

The default value is false. Note that this setting is only applicable if the SignCustomRequest setting is true; it is ignored otherwise.

IncludeObjectMD5:   Whether an MD5 digest of a object's data should be included.

If set to true, the class will include an MD5 digest of an object's data when it is created using CreateObject. (If the class performs an automatic multipart upload, MD5 digests of the individual parts' data will be sent instead, even if IncludePartMD5 is false.)

The default value is false.

MaxObjects:   The maximum number of results to return when listing objects.

This setting specifies the maximum number of results that should be returned by a call to ListObjects or ListMultipartUploads.

If this setting is -1 (default), the server's default (1000) is used. Acceptable values are 1 to 1000 (inclusive).

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 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 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 OAuthRefreshToken property 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 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.

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 - 1).

The current element is specified in the 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 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 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 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 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 JWTXPath setting allows you to point to specific claims within the payload of a JWT based access token.

XPath Syntax

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:
DescriptionJSON 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 JWTXText.

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 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 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 OAuthClientProfile is ocpWeb 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:

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

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

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 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 for details.

OAuthPasswordGrantUsername:   Used in the Resource Owner Password grant type.

Used to set the username property when the OAuthGrantType is set to the password grant type and Authorize is called.

OAuthPKCEChallengeEncoding:   The PKCE code challenge method to use.

This setting controls the PKCE code challenge method used when 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 method and the OAuthWebAuthURL field when OAuthUsePKCE is set to true. When using the cocpWeb OAuthClientProfile, the configuration setting can be set instead to allow the authorization request to be made from a different instance than the authentication (token) request.

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

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 OAuthGrantType. The 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 is called. In certain cases, it is required to start the webserver before calling Authorize. For example, if the OAuthReturnURL 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 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 property specifies the type of the certificate store specified by OAuthWebServerCertStore. If the store is password protected, specify the password in OAuthWebServerCertStorePassword.

OAuthWebServerCertStore is used in conjunction with the OAuthWebServerCertSubject property in order to specify the certificate to be used during SSL.

Designations of certificate stores are platform-dependent.

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

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

Note: This is required when 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 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 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=support@nsoftware.com". Common fields and their meanings are displayed below.

FieldMeaning
CNCommon Name. This is commonly a host name like www.server.com.
OOrganization
OUOrganizational Unit
LLocality
SState
CCountry
EEmail Address

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

Note: This is required when OAuthWebServerSSLEnabled is set to true.

OAuthWebServerFailedResponse:   The custom response that will be displayed to the user if authentication failed.

When Authorize 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 OAuthClientProfile is set to cocpApplication. This specifies the interface on which the embedded web server listens, and also the value displayed in the OAuthReturnURL. 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 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.

Prefix[i]:   The i'th common prefix returned.

When StorePrefixList is enabled, this setting can be used to retrieve the common prefixes returned by the most recent ListObjects request. Refer to that method, as well as the ObjectDelimiter property, for more information.

Valid values for i are from 0 to (PrefixCount - 1).

PrefixCount:   The number of common prefixed returned.

When StorePrefixList is enabled, this setting reflects the number of common prefixes returned by the most recent ListObjects request.

This setting is always -1 when StorePrefixList is disabled.

ProgressAbsolute:   Whether the class should track transfer progress absolutely.

This setting controls whether the class tracks upload and download progress absolutely or relatively, with regards to the values reported via the Progress event when an interrupted transfer is resumed.

If this setting is enabled (default), then when a transfer is interrupted and later resumed, the values reported by the Progress event will account for the data that was successfully transferred before the interruption.

If this setting is disabled, then the class will treat resumed transfers as "new" transfers, and the values reported by the Progress event will start at 0 rather than from the number of bytes already transferred.

Refer to the Progress event for more information.

ProgressStep:   How often the progress event should be fired, in terms of percentage.

This setting controls how often the class will fire the Progress event during an upload or download, in terms of percentage. Valid values are 0 to 99, inclusive.

The default value, 1, will cause the Progress event to fire each time the event's PercentDone parameter value increases by one percent. Setting this setting to 0 will cause the Progress event to fire every time data is transferred.

Note that the Progress event will always fire once at the beginning and end of a transfer, regardless of this setting's value. Also, if PercentDone cannot be calculated for a particular transfer (e.g., for downloads that use chunked transfer encoding), then the class will behave as if this setting were 0 for the duration of the transfer.

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.

SecretKey:   The Secret Access Key Id for the Google account.

This config describes the secret key to the Google account. It should not be shared with others. The SecretKey is used along with the AccessKey in the authentication process with Google servers.

SendObjectACLs:   Whether to include object-level ACL headers when making requests.

This setting controls whether object-level ACL headers are included when making applicable requests (e.g., CreateObject). It may be necessary to disable this setting if uniform bucket-level access is being used.

By default, this setting is enabled, and object-level ACL headers are included.

SignCustomRequest:   Tells the class to sign the outgoing request.

By default, this configuration is true, and when SendCustomRequest is called the class will sign the specified request to authenticate with the service. If set to false, the request will be sent as is, without signing.

StorageClass:   Specify the storage class to be used for the uploaded object.

This setting specifies the storage class to use for newly-created objects. Some valid string values (case-insensitive) include: STANDARD, MULTI_REGIONAL, REGIONAL, NEARLINE, COLDLINE

Refer to Google's documentation for more information about each storage class.

Note: This option only applies to the CreateObject and CopyObject methods.

StoreObjectData:   Whether class stores object data or not.

This configuration setting can be used to instruct the class whether or not to create a local copy of the data to upload when setting the ObjectData property. When set to false, the class will store the data address and length only. This cuts down on the memory usage of the class when uploading files.

The default value for this setting is true.

StorePrefixList:   Whether to store the common prefixes returned when listing objects.

If this setting is enabled, the class will populate the PrefixCount and Prefix[i] settings anytime ListObjects is called.

By default, this setting is disabled.

TempPath:   The path to the directory where temporary files are created.

This setting specifies the path where temporary files are created when downloading encrypted files. If not specified, the system's temporary directory is used. Refer to DownloadTempFile and DownloadFile for more information.

URL:   If set, the default URL will be overridden by this value.

By default, the class uses the service's URL. Setting this config will override this value.

XChildCount:   The number of child elements of the current element.

The number of child attributes of the current element. The XChild configuration settings will be indexed from 0 to (XChildCount - 1).

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XChildName[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 via the XPath configuration setting. This configuration setting is read-only.

XChildXText[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 via the XPath configuration setting. This configuration setting is read-only.

XElement:   The name of the current element.

Provides the name of the current element.

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XParent:   The parent of the current element.

Provides the parent of the current element.

The current element is specified via the 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 setting allows you to point to specific elements in the XML or JSON response.

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

XPath Syntax

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 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.

XPath Examples

Assuming the following XML response:

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

Or, alternatively, the following JSON response:

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

Here are some examples of valid XPaths:

DescriptionXML 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 is not an exhaustive list by any means, but should provide a general idea of the possibilities.

XSubTree:   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 via the XPath configuration setting. This configuration setting is read-only.

XText:   The text of the current element.

Provides the inner text of the current element.

The current element is specified in the XPath configuration setting. This configuration setting is read-only.

HTTP Config Settings

AcceptEncoding:   Used to tell the server which types of content encodings the client supports.

When 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 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. When set to True, downloaded data will be appended to LocalFile. This may be used in conjunction with Range to resume a failed download. This is applicable only when LocalFile is set. The default value is False.

Authorization:   The Authorization string to be sent to the server.

If the 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 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 event, by BytesTransferred.

ChunkSize:   Specifies the chunk size in bytes when using chunked encoding.

This is applicable only when 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"), 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 after calling a method. The 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: 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 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 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 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 ProxyUser and ProxyPassword are specified, this value is calculated using the algorithm specified by ProxyAuthScheme.

ProxyAuthScheme:   The authorization scheme to be used for the proxy.

This configuration setting is provided for use by classs 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 classs that do not directly expose Proxy properties.

ProxyPort:   Port for the proxy server (default 80).

This configuration setting is provided for use by classs 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 classs 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 classs 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 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 Http http = new Http(); http.Config("TransferredRequest=on"); http.PostData = "body"; http.Post("http://someserver.com"); Console.WriteLine(http.Config("TransferredRequest")); C++ 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 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 setting must be set to a value capable of interpreting the specified host name. For instance, to specify UTF-8, set 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 ProxyAutoDetect 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 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 classs that do not directly expose Firewall properties.

FirewallHost:   Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the 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 classs that do not directly expose Firewall properties.

FirewallPassword:   Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and 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 classs that do not directly expose Firewall properties.

FirewallPort:   The TCP port for the FirewallHost;.

The FirewallPort is set automatically when FirewallType is set to a valid value.

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

FirewallType:   Determines the type of firewall to connect through.

The appropriate values are as follows:

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

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

FirewallUser:   A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and 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 classs 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 will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by 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 will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by 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 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 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 is a positive value, the system will attempt to send pending data until the specified 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 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 multi-homed 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 classs) only through that interface.

If the class is connected, the LocalHost 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 multi-homed hosts (machines with more than one IP interface).

LocalPort:   The port in the local host where the class binds.

This 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; setting is useful when trying to connect to services that require a trusted port in 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 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 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 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 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.nsoftware.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 and 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 true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this config 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:

0 IPv4 Only
1 IPv6 Only
2 IPv6 with IPv4 fallback

SSL Config Settings

LogSSLPackets:   Controls whether SSL packets are logged when using the internal security API.

When SSLProvider is set to Internal, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful for debugging purposes.

When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.

Enabling this setting has no effect if SSLProvider 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 etc). OpenSSL recommends to use 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

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

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

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

sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please 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 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:

/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 certificate to use during SSL client authentication.

This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

..
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLCipherStrength:   The minimum cipher strength used for bulk encryption.

This minimum cipher strength 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.

Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.

Use this 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 is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.

SSLEnabledCipherSuites:   The cipher suite to be used in an SSL negotiation.

The enabled 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 is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Example values when SSLProvider is set to Platform: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); Possible values when SSLProvider is set to Platform include:

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

  • TLS_AES_256_GCM_SHA384
  • TLS_CHACHA20_POLY1305_SHA256
  • TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

SSLEnabledProtocols:   Used to enable/disable the supported security protocols.

Used to enable/disable the supported security protocols.

Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:

TLS1.312288 (Hex 3000)
TLS1.23072 (Hex C00) (Default)
TLS1.1768 (Hex 300) (Default)
TLS1 192 (Hex C0) (Default)
SSL3 48 (Hex 30)
SSL2 12 (Hex 0C)

SSLEnabledProtocols - TLS 1.3 Notes

By default when TLS 1.3 is enabled the class will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.

In editions which are designed to run on Windows SSLProvider 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 only supported 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 only available on Windows 11 / Windows Server 2022 and up.
  • SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
  • If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2 the above 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.

SSLEnableRenegotiation:   Whether the renegotiation_info SSL extension is supported.

This setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This setting is true by default, but can be set to false to disable the extension.

This setting is only applicable when SSLProvider is set to Internal.

SSLIncludeCertChain:   Whether the entire certificate chain is included in the SSLServerAuthentication event.

This setting specifies whether the Encoded parameter of the SSLServerAuthentication 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 event.

If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication 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 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 traffice for debugging purposes. When writing to this file the class will only append, it will not overwrite previous values.

Note: This setting is only applicable when SSLProvider is set to Internal.

SSLNegotiatedCipher:   Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipher[connId]");

SSLNegotiatedCipherStrength:   Returns the negotiated cipher suite strength.

Returns the strength of the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g.TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherStrength[connId]");

SSLNegotiatedCipherSuite:   Returns the negotiated cipher suite.

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 setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherSuite[connId]");

SSLNegotiatedKeyExchange:   Returns the negotiated key exchange algorithm.

Returns the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchange[connId]");

SSLNegotiatedKeyExchangeStrength:   Returns the negotiated key exchange algorithm strength.

Returns the strenghth of the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchangeStrength[connId]");

SSLNegotiatedVersion:   Returns the negotiated protocol version.

Returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedVersion[connId]");

SSLSecurityFlags:   Flags that control certificate verification.

The following flags are defined (specified in hexadecimal notation). They can be or-ed together to exclude multiple conditions:

0x00000001Ignore time validity status of certificate.
0x00000002Ignore time validity status of CTL.
0x00000004Ignore non-nested certificate times.
0x00000010Allow unknown Certificate Authority.
0x00000020Ignore wrong certificate usage.
0x00000100Ignore unknown certificate revocation status.
0x00000200Ignore unknown CTL signer revocation status.
0x00000400Ignore unknown Certificate Authority revocation status.
0x00000800Ignore unknown Root revocation status.
0x00008000Allow test Root certificate.
0x00004000Trust test Root certificate.
0x80000000Ignore non-matching CN (certificate CN not-matching server name).

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

SSLServerCACerts:   A newline separated list of CA certificate to use during SSL server certificate validation.

This setting optionally specifies one or more CA certificates to be used when 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 setting should only be set 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 setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

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

TLS12SignatureAlgorithms:   Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.

This setting specifies the allowed server certificate signature algorithms when SSLProvider is set to Internal and 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 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: 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 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.

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

TLS12SupportedGroups:   The supported groups for ECC.

This 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 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 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 round trip 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 setting.

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

In most cases this setting does not need to be modified. This should only be modified 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)

Socket Config Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for 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 TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

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. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

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.

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.
MaskSensitive:   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.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

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 FIPS, while all the 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 which 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 article.

Note: This setting is only applicable on Windows.

Note: Enabling FIPS-compliance requires a special license; please contact sales@nsoftware.com for details.

UseInternalSecurityAPI:   Tells the class 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 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 section.
