# AzureSecrets Module

The AzureSecrets module makes it easy to interact with secrets in Azure Key Vaults.

## Syntax

```text
CloudKeys.AzureSecrets
```

## Remarks

The AzureSecrets class provides an easy-to-use interface for the secret-related functionality of the Azure Key Vault service. Azure Key Vault allows you to work with a few different kinds of resources, one of which is *secrets* (e.g., passwords, symmetric keys, etc.). This class helps you to create and manage said secrets. To work with asymmetric key pairs instead, refer to the [AzureKeys](AzureKeys.md#AzureKeys) class.

To begin, register for an Azure account and create one or more Key Vaults via the Azure Portal. Set the [Vault](#vault-property-azuresecrets-module) property to the name of the vault you wish to work with.

This class requires authentication via OAuth 2.0. First, perform OAuth authentication using the [OAuth](#oauth-property-azuresecrets-module) property to set the appropriate fields for the chosen OAuthClientProfile and OAuthGrantType.

The component has the following defaults:

|  |  |
| --- | --- |
| Authorization Server URL | "https://login.microsoftonline.com/common/oauth2/v2.0/authorize" |
| Token Server URL | "https://login.microsoftonline.com/common/oauth2/v2.0/token" |
| Scopes | "offline_access https://vault.azure.net/user_impersonation" |

Additionally, depending on how the application is registered (Ex. Single-tenant, Multi-tenant) and what OAuthGrantType is selected (Ex. Authorization Code, Password), it may be required to use the tenant ID rather than "common" in the OAuthServerAuthURL, and OAuthServerTokenURL properties. See below for examples of the modified URLs:

|  |  |
| --- | --- |
| Authorization Server URL | "https://login.microsoftonline.com/{TENANT_ID}/oauth2/v2.0/authorize" |
| Token Server URL | "https://login.microsoftonline.com/{TENANT_ID}/oauth2/v2.0/token" |

 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](#authorize-method-azuresecrets-module) 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](#authorize-method-azuresecrets-module) 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](#authorize-method-azuresecrets-module) 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](#authorize-method-azuresecrets-module) method is called, the [OAuthAutomaticRefresh](#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](#authorize-method-azuresecrets-module) 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: **

```csharp
AzureSecrets azuresecrets = new AzureSecrets();

azuresecrets.OAuth.ClientProfile = CloudOAuthClientProfiles.cocpApplication;
azuresecrets.OAuth.GrantType = OAuthSettingsGrantTypes.cogtAuthorizationCode;
azuresecrets.OAuth.ClientId = CLIENT_ID;
azuresecrets.OAuth.ClientSecret = SECRET_ID;
azuresecrets.OAuth.AuthorizationScope = "offline_access https://vault.azure.net/user_impersonation";
azuresecrets.OAuth.ServerAuthURL = "https://login.microsoftonline.com/" + TENANT_ID + "/oauth2/v2.0/authorize";
azuresecrets.OAuth.ServerTokenURL = "https://login.microsoftonline.com/" + TENANT_ID + "/oauth2/v2.0/token";

azuresecrets.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](#authorize-method-azuresecrets-module) method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the class will parse the *access token* from the redirect.

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

**Password**

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

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

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

### Web Profile

 This profile is similar to setting the class to the Application profile and Authorization Code grant type except the class will not launch the browser. It is typically used in situations where there is a back-end that is supporting some front end. This profile expects that OAuthClientId, OAuthClientSecret, OAuthServerAuthURL, OAuthServerTokenURL, and the OAuthReturnURL properties to be set. Before calling the [Authorize](#authorize-method-azuresecrets-module) 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](#authorize-method-azuresecrets-module) 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](#authorize-method-azuresecrets-module) method can immediately be called to make a request to the token server to get a new *access token*.

### External OAuth Support

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

```text
Bearer ACCESS_TOKEN_VALUE
```

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

 For Example:

```csharp
Oauth oauth = new Oauth();

oauth.ClientId = "CLIENT_ID";
oauth.ClientSecret = "CLIENT_SECRET";
oauth.ServerAuthURL = "https://login.microsoftonline.com/common/oauth2/v2.0/authorize";
oauth.ServerTokenURL = "https://login.microsoftonline.com/common/oauth2/v2.0/token";
oauth.AuthorizationScope = "offline_access https://vault.azure.net/user_impersonation";
oauth.GrantType = OauthGrantTypes.ogtAuthorizationCode;

azuresecrets.Authorization = oauth.GetAuthorization();
```

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

### Using the Class

Secrets can be created using the [CreateSecret](#createsecret-method-azuresecrets-module) method. A secret's name must be set at the time of creation, and cannot be changed later. The secret's value and, optionally, content type must also be set, but can be changed at any time. To change a secret's value, create a new version of it using the [CreateSecret](#createsecret-method-azuresecrets-module) method (which will always create a new version if a secret with the specified name already exists); to change a secret's content-type, use the [UpdateSecret](#updatesecret-method-azuresecrets-module) method.

To retrieve a secret and its information, use the [GetSecret](#getsecret-method-azuresecrets-module) method.

When a secret will no long be used, it can be deleted using the [DeleteSecret](#deletesecret-method-azuresecrets-module) method. However, the secret will only be soft-deleted; by default, Azure will permanently delete it after the waiting period configured for the vault. During this waiting period, the soft-deleted secret may be recovered using [RecoverSecret](#recoversecret-method-azuresecrets-module), or permanently deleted using [PurgeSecret](#purgesecret-method-azuresecrets-module) (assuming the currently-authenticated user has the permissions to do so).

```csharp
// Create a secret.
azuresecrets.SecretData = "Test123";
azuresecrets.CreateSecret("mysecret", "text/plain");

// Download the secret value to a local file.
azuresecrets.LocalFile = "C:\temp\secret.txt";
azuresecrets.GetSecret("mysecret");

// Create a new version of the secret.
azuresecrets.SecretData = "Cats456";
azuresecrets.CreateSecret("mysecret", "text/plain");

// ... Some time later, when the secret is no longer needed ...
azuresecrets.DeleteSecret("mysecret");

// At this point, the secret is only soft-deleted. It could be recovered...
azuresecrets.RecoverSecret("mysecret");
// ...or permanently deleted.
azuresecrets.PurgeSecret("mysecret");
```

To list secrets, use the [ListSecrets](#listsecrets-method-azuresecrets-module) method. This method is also used to list soft-deleted secrets if the [GetDeleted](#GetDeleted) configuration setting has been enabled first. To list a secret's versions, use the [ListVersions](#listversions-method-azuresecrets-module) method. (You cannot list a deleted secret's versions.)

```csharp
// If there are many secrets to list, there may be multiple pages of results. This will
// cause all pages of results to be accumulated into the Secrets collection property.
do {
  azuresecrets.ListSecrets();
} while (!string.IsNullOrEmpty(azuresecrets.SecretMarker));

// A similar thing applies to secret versions as well.
do {
  azuresecrets.ListVersions("mysecret");
} while (!string.IsNullOrEmpty(azuresecrets.VersionMarker));
```

The class also supports a variety of other functionality, including:

- Enabling and disabling secrets with [SetSecretEnabled](#setsecretenabled-method-azuresecrets-module).
- Tagging support using [AddTag](#addtag-method-azuresecrets-module) and the [Tags](#tags-property-azuresecrets-module) collection.
- Secure secret backup and restoration using [BackupSecret](#backupsecret-method-azuresecrets-module) and [RestoreSecret](#restoresecret-method-azuresecrets-module).
- And more!

  set {...}
}
```

## Default Value

False

## Remarks

This property specifies whether the class should automatically base64-encode secret data when it is uploaded by [CreateSecret](#createsecret-method-azuresecrets-module), and base64-decode it when it is downloaded with [GetSecret](#getsecret-method-azuresecrets-module).

Secrets are stored on the server as strings, and are transported via a JSON string property, so binary values must be encoded in some way; this property is provided as a convenience.

# Firewall Property ([AzureSecrets](#azuresecrets-module) Module)

A set of properties related to firewall access.

## Syntax

```text
public var firewall: Firewall {
  get {...}
  set {...}

func onSecretList(name: String, versionId: String, contentType: String, enabled: Bool, creationDate: Int64, updateDate: Int64, deletionDate: Int64, purgeDate: Int64)
```

## Remarks

This event fires once for each secret (or secret version) returned when [ListSecrets](#listsecrets-method-azuresecrets-module), [ListVersions](#listversions-method-azuresecrets-module), or [GetSecret](#getsecret-method-azuresecrets-module) is called.

*Name* reflects the name of the secret.

*VersionId* reflects the Id of the secret version.

*ContentType* reflects the secret's content type.

*Enabled* reflects whether the secret is currently enabled.

*CreationDate* reflects the secret's creation date, in seconds since the Unix epoch.

*UpdateDate* reflects the secret's update date, in seconds since the Unix epoch.

*DeletionDate* reflects the secret's deletion date, in seconds since the Unix epoch, or *-1* if the secret has not been deleted.

# SSLServerAuthentication Event ([AzureSecrets](#azuresecrets-module) Module)

Fired after the server presents its certificate to the client.

## Syntax

```text
func onSSLServerAuthentication(certEncoded: Data, certSubject: String, certIssuer: String, status: String, accept: inout Bool)
```

## Remarks

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

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

# SSLStatus Event ([AzureSecrets](#azuresecrets-module) Module)

Fired when secure connection progress messages are available.

## Syntax

```text
func onSSLStatus(message: String)
```

## Remarks

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

# StartTransfer Event ([AzureSecrets](#azuresecrets-module) Module)

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

## Syntax

```text
func onStartTransfer(direction: Int32)
```

## Remarks

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

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

# TagList Event ([AzureSecrets](#azuresecrets-module) Module)

Fires once for each tag returned when a secret is retrieved.

## Syntax

```text
func onTagList(secretName: String, versionId: String, name: String, value: String)
```

## Remarks

This event fires once for each tag returned when [GetSecret](#getsecret-method-azuresecrets-module) is called.

*SecretName* reflects the name of the secret.

*VersionId* reflects the Id of the secret version.

*Name* reflects the name of the tag.

*Value* reflects the value of the tag.

# Transfer Event ([AzureSecrets](#azuresecrets-module) Module)

Fired while a document transfers (delivers document).

## Syntax

```text
func onTransfer(direction: Int32, bytesTransferred: Int64, percentDone: Int32, text: Data)
```

## 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.

# Config Settings ([AzureSecrets](#azuresecrets-module) Module)

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

### AzureSecrets Config Settings

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

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

**APIVersion**: The Azure Key Vault API version that the class conforms to.This setting can be queried to obtain the Azure Key Vault API version that the class conforms to; it cannot be changed.

**CreateSecretEnabled**: Whether new secrets should be created in an enabled or disabled state.This setting specifies whether new secrets created using the [CreateSecret](#createsecret-method-azuresecrets-module) method should be created in an enabled or disabled state.

By default, this setting is enabled, and secrets are created in an enabled state.

**ExpiryDate**: The expiry date to send for the secret.This setting specifies the expiry date that should be sent when a secret is created using [CreateSecret](#createsecret-method-azuresecrets-module) or updated using [UpdateSecret](#updatesecret-method-azuresecrets-module). The date should be specified in seconds since the Unix epoch.

Note that expiry dates are purely informational; Azure does not enforce any additional restrictions based on whether a secret has expired.

By default, this setting is set to *-1*, and no expiry date is sent.

**GetDeleted**: Whether the class should retrieve information about soft-deleted secrets.This setting specifies whether the class should retrieve information about soft-deleted secrets when [ListSecrets](#listsecrets-method-azuresecrets-module) or [GetSecret](#getsecret-method-azuresecrets-module) is called.

By default, this setting is disabled, and the class requests information about active secrets.

**MaxSecrets**: The maximum number of results to return when listing secrets.This setting specifies the maximum number of results that should be returned by a call to [ListSecrets](#listsecrets-method-azuresecrets-module) or [ListVersions](#listversions-method-azuresecrets-module).

If this setting is *-1* (default), the server's default (25) is used. Otherwise, the setting must be set to a value greater than or equal to *1*.

**NotBeforeDate**: The 'not before' date to send for the secret.This setting specifies the "not before" date that should be sent when a secret is created using [CreateSecret](#createsecret-method-azuresecrets-module) or updated using [UpdateSecret](#updatesecret-method-azuresecrets-module). The date should be specified in seconds since the Unix epoch.

Note that "not before" dates are purely informational; Azure does not enforce any additional restrictions based on whether a secret is awaiting its "not before" date.

By default, this setting is set to *-1*, and no "not before" date is sent.

**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.

**VersionId**: The Id of the secret version that the class should make requests against.This setting can be set to the Id of a specific secret version before calling the [GetSecret](#getsecret-method-azuresecrets-module) or [UpdateSecret](#updatesecret-method-azuresecrets-module) method in order to have the class make the request against the specified version rather than the latest version.

Note that, in the case of [GetSecret](#getsecret-method-azuresecrets-module), this setting is ignored if the [GetDeleted](#GetDeleted) setting is enabled.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

 NOTE: XPath indices are *1-based*.

For example, assume the following XML and JSON responses.

XML:

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

JSON:

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

The following are examples of valid XPaths for these responses:

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

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

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

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

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

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

### OAuth Config Settings

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

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

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

**OAuthAutomaticRefresh**: Whether or not to refresh an expired access token automatically.When this setting is set to *true* and the [Authorization](#authorization-property-azuresecrets-module) 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](#authorize-method-azuresecrets-module) if it is empty.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

**OAuthPasswordGrantUsername**: Used in the Resource Owner Password grant type.Used to set the username property when the OAuthGrantType is set to the password grant type and [Authorize](#authorize-method-azuresecrets-module) is called.

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

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

**OAuthPKCEVerifier**: The PKCE verifier used to generate the challenge.This configuration setting when queried provides the PKCE verifier that is used to generate the PKCE challenge for the [Authorize](#authorize-method-azuresecrets-module) method and the OAuthWebAuthURL field when [OAuthUsePKCE](#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.

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

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

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

.NET

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

 C++

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

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

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

This setting can also be set to activate or deactivate the web server. Under normal circumstances, this would not be required as the class will automatically start and stop the web server when [Authorize](#authorize-method-azuresecrets-module) is called. In certain cases, it is required to start the webserver before calling [Authorize](#authorize-method-azuresecrets-module). 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](#OAuthReUseWebServer) is set to true, the server will not be automatically stopped, and this configuration setting must be set to *"false"* to stop the embedded web server.

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

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

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

 Designations of certificate stores are platform dependent.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

### HTTP Config Settings

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

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

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

The default value is True.

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

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

The default value is True.

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

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

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

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

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

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

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

The default value is False.

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

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

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

**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 instead.

Following are the valid options:

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

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

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

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

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

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

**HTTP/2 Notes**

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

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

**HTTP/3 Notes**

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

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

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

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

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

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

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

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

**LogLevel**: The level of detail that is logged.This configuration setting controls the level of detail that is logged through the [Log](#log-event-azuresecrets-module) 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 .

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

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

**ProxyAuthorization**: The authorization string to be sent to the proxy server.This is similar to the [Authorization](#Authorization) configuration setting, but is used for proxy authorization. If this configuration setting contains a nonempty string, a *Proxy-Authorization* HTTP request header is added to the request. This header conveys proxy Authorization information to the server. If 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 classes that do not directly expose Proxy properties.

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

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

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

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

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

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

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

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

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

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

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

 .NET

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

 C++

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

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

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

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

The default value is False and the hostname will always be used exactly as specified. NOTE: The [CodePage](#CodePage) setting must be set to a value capable of interpreting the specified host name. For instance, to specify UTF-8, set [CodePage](#CodePage) to *65001*.

**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](#timeout-property-azuresecrets-module) for establishing a connection and transmitting/receiving data.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

NOTE: This value is not applicable in macOS.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

NOTE: This value is not applicable in Java.

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

By default, this configuration setting is set to False.

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

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

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

### SSL Config Settings

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

**SSLCheckCRL**: Whether to check the Certificate Revocation List for the server certificate.This configuration setting specifies whether the class will check the Certificate Revocation List (CRL) specified by the server certificate. If set to 1 or 2, the class will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The class will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the class .

When set to 0 (default), the CRL check will not be performed by the class. When set to 1, it will attempt to perform the CRL check, but it will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.

This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.

**SSLCheckOCSP**: Whether to use OCSP to check the status of the server certificate.This configuration setting specifies whether the class will use OCSP to check the validity of the server certificate. If set to 1 or 2, the class will first obtain the Online Certificate Status Protocol (OCSP) URL from the server certificate's OCSP extension. The class will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation, the class .

When set to 0 (default), the class will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but it will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.

This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.

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

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

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

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

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

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

```text

-----END CERTIFICATE-----
```

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

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

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

Multiple cipher suites are separated by semicolons.

Example values when [SSLProvider](#sslprovider-property-azuresecrets-module) is set to *Platform* include the following:

```text
obj.config("SSLEnabledCipherSuites=*");

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

- TLS_AES_256_GCM_SHA384
- TLS_CHACHA20_POLY1305_SHA256
- TLS_AES_128_GCM_SHA256

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

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

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

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

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

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

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

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

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

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

**SSLEnabledProtocols: SSL2 and SSL3 Notes: **

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

```text
-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

- "ecdhe_x25519" (default)
- "ecdhe_x448"
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)

- "ffdhe_3072" (default)
- "ffdhe_4096"
- "ffdhe_6144"
- "ffdhe_8192"

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

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

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

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

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

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

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

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

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

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

### Socket Config Settings

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

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

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

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

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

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

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

### Base Config Settings

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

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

The following is a list of valid code page identifiers:

|  |  |
| --- | --- |

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

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

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

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

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

 This setting is set to *false* by default on all platforms.
