SAML Class

Properties Methods Events Config Settings Errors

The SAML class provides an easy way to add SAML based SSO to your application.

Syntax

cloudsso.SAML

Remarks

The Security Assertion Markup Language (SAML) protocol provides a standardized way to add Single Sign-on (SSO) to applications. Service Providers (IE. Your application) using SAML-based SSO can eliminate the need to store and manage user passwords. When using SAML the responsibility of identifying a user can be shifted to the Identity Provider.

In a Web environment this is typically done by redirecting a user with a SAMLRequest from your application, to the Identity Provider's login page where a user already has an account. The user will login and the Identity Provider will return an Assertion which is a set of information about the user and the authentication steps taken to identify the user.

When a Service Provider (ie. your web application) receives this SAMLResponse, it will verify both the SAMLResponse and its accompanying Assertion to ensure that both were requested by the Service Provider and issued by the Identity Provider. Once the SAMLResponse and Assertion have been verified, the assertion will typically contain attributes about the user and its profile with the Identity Provider.

SAML also supports Single Logout (SLO) that can be used to log a user out of the Identity Provider and, depending on the configuration of the Identity Provider, all other accounts that used the Identity Provider to authenticate the user.

Setup

To get started with the class information about the Identity Provider is needed. Typically this information is provided by a SAML Metadata Document is either provided during the setup or requested from a URI. The RequestIdentityMetadata and LoadIdentityMetadata methods are both ways to set the IdentityProviderMetadata, IdentityProviderSigningCert, and IdentityProviderURIs properties and collection.

Usage: Requesting and Reloading Identity Provider Metadata Document

saml.RequestIdentityMetadata("https://example.com/federationmetadata/federationmetadata.xml"); string raw_document = saml.IdentityProviderMetadata.MetadataContent; //... saml.LoadIdentityMetadata(raw_document, true);

Additionally, the class needs to be configured with the information about the Service Provider (ie. your application). The ServiceProviderMetadata, ServiceProviderSigningCert, and ServiceProviderURIs properties can be used to provide information about the Service Provider. This is used by the class to build SAML requests and to verify SAML responses and assertions. Additionally, to easily supply this information to an Identity Provider, the BuildServiceMetadata method can be used to create a SAML Metadata Document.

Usage: Configuring Service Provider Metadata

saml.ServiceProviderMetadata.EntityId = "ServiceProviderId"; saml.ServiceProviderMetadata.AuthnRequestSigned = true; saml.ServiceProviderMetadata.WantAssertionsSigned = true; saml.ServiceProviderSigningCert = new Certificate(CertStoreTypes.cstPFXFile, "cert.pfx", "password", "*"); URI acs = new URI(); acs.URIType = SAMLURITypes.sutACS; acs.Location = "https://service_provider.com/acs/"; acs.BindingType = subPost; saml.ServiceProviderURIs.Add(acs); URI logout = new URI(); logout.URIType = SAMLURITypes.sutLogout; logout.Location = "https://service_provider.com/logout/"; logout.Binding = subRedirect ; saml.ServiceProviderURIs.Add(acs); saml.BuildServiceMetadata();

Authentication Request

Once configured, the BuildAuthnRequest method can be used to build a SAMLRequest that has been configured by the SAMLRequestSettings. Additionally, to provide state information between the request and the response, the RelayState property can be set. When provided by the Service Provider, the Identity Provider will return the same value with the SAMLResponse. For example, this can be used to return the user back to the page that they were on when they initiated the authentication flow.

Usage: Building an Authn Request

saml.SAMLRequestSettings.RequestBinding = SAMLRequestBindings.srbHTTPRedirect; saml.SAMLRequestSettings.SignRequest = true; saml.RelayState = "https://service_provider.com/landing"; saml.BuildAuthnRequest();

Depending on how the RequestBinding field is configured, the results will be provided through the SAMLRequestBody and SAMLRequestURL properties. Using the information from the properties, the user that needs identifying should be directed to the SAMLRequestURL. If using the srbHTTPRedirect binding, then this is typically done by redirecting the user to the URL. This URL will contain the SAMLRequest and RelayState as query parameters that are parsed by the Identity Provider. If using the srbHTTPPost binding, then this is done by using an HTML form post as seen below:

string htmlContent = $@" <!DOCTYPE html > <html > <head > <title >SAML POST </title > </head > <body onload='document.forms[0].submit()' > <form method='post' action='{saml.SAMLRequestURL}' > <input type='hidden' name='SAMLRequest' value='{saml.SAMLRequestBody}' / > <input type='hidden' name='RelayState' value='{saml.RelayState}' / > </form > </body > </html >";

Authentication Response

Once the user has completed authentication, the Identity Provider will return the user to the Assertion Consumer Service (ASC) URI that was configured in the ServiceProviderURIs collection. If authentication was successful, this response should also contain an Assertion as well as information about the authentication context.

To handle an incoming HTTP request, the ProcessHTTPRequest and ParseHTTPRequest methods should be used. By default these methods will attempt to read the HTTP request headers and body from the specified HttpServletRequest object. To provide HTTP headers and body directly to the classthe HTTPRequestHeaders and HTTPRequest properties can be set before calling ParseHTTPRequest or ProcessHTTPRequest.

To start processing the HTTP Request call the ProcessHTTPRequest method. While the ProcessHTTPRequest method is processing the HTTP Request, the class fires the SAMLResponse and Assertion events. These events can be used to provide information about the original request or the Identity Provider. If the SAMLResponse and Assertion are valid, then the method will return without any errors. Additionally the SAMLResponseInfo, AssertionInfo, AssertionAttributeInfo, and AssertionAuthnInfo properties and collection will be populated.

The ProcessHTTPRequest performs multiple steps automatically making it a simple method to handle incoming requests. If needed, the ParseHTTPRequest, ParseSAMLResponse, and ParseAssertion methods can be used to perform each operation individually instead of relying on the ProcessHTTPRequest method.

FollowRedirects Property (SAML Class)

This property determines what happens when the server issues a redirect.

Syntax


public int getFollowRedirects();


public void setFollowRedirects(int followRedirects);


Enumerated values:
  public final static int frNever = 0;
  public final static int frAlways = 1;
  public final static int frSameScheme = 2;

Default Value

Remarks

This property 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 frAlways (1), the new URL for the object is retrieved automatically every time.

If this property is set to frSameScheme (2), the new URL is retrieved automatically only if the URLScheme is the same; otherwise, the class throws an exception.

Note: Following the HTTP specification, unless this property is set to frAlways (1), 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. If, however, this property is set to frAlways (1), 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 frNever (0). In this case, redirects are never followed, and the class throws an exception instead.

HTTPRequest Property (SAML Class)

The HTTP body for the current HTTP Request.

Syntax


public byte[] getHTTPRequest();


public void setHTTPRequest(byte[] HTTPRequest);

  public final static int sslpInternal = 2;

Default Value

Remarks

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

Possible values are as follows:


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

Additional Notes

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

When Automatic is selected, the platform implementation is used by default. When TLS 1.3 is enabled via SSLEnabledProtocols, the internal implementation is used.

SSLServerCert Property (SAML Class)

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

Remarks

Uses the SAMLRequestSettings settings to build a SAMLRequest that is meant for authenticating the current user. To help keep track of a user's state in your application, the RelayState property can be set to add a RelayState to the request. The value set in the RelayState property will then be present in the response from the Identity Provider. After the request is built, the following properties are set depending on how the RequestBinding field is set.

HTTP Redirect - SAMLRequestURL
HTTP Post - SAMLRequestURL, SAMLRequestBody

BuildLogoutRequest Method (SAML Class)

Build a Single Logout request.

Syntax

public void buildLogoutRequest(String nameIdentifier);

Remarks

This method uses the SAMLRequestSettings property to build a SAMLRequest that is meant for logging out the user identified by the NameIdentifier parameter. To help keep track of a user's state in your application, the RelayState property can be set to add a RelayState to the request. The value set in the RelayState property will then be present in the response from the Identity Provider. Typically, if supported, the identity provider will also issue logout requests for all other sessions that are active for the user. After the request is built, the following properties are set depending on how the RequestBinding field is set.

HTTP Redirect - SAMLRequestURL
HTTP Post - SAMLRequestURL, SAMLRequestBody

BuildServiceMetadata Method (SAML Class)

Build a metadata document for a service provider.

Syntax

public void buildServiceMetadata();

This method uses the ServiceProviderMetadata properties to create a new federation metadata document that describes the service provider. This is typically used to provide the information about the service provider to the identity provider. The following fields and properties are used.

AuthnRequestSigned
EntityId
SignedMetadata
SupportedNameIdFormats
WantAssertionsSigned
ServiceProviderSigningCert
ServiceProviderURIs

Config Method (SAML Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

Remarks

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

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

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

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

DoEvents Method (SAML Class)

This method processes events from the internal message queue.

Syntax

public void doEvents();

Remarks

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

GetAssertionAttribute Method (SAML Class)

Search for a specific assertion attribute.

Syntax

public String getAssertionAttribute(String attrName);

Remarks

This method will search the current AssertionAttributeInfo collection for a specific attribute. The attrName parameter should be set to the attribute name. The method will then return the value of the attribute with the matching name. If there is more than one value, then it will return the values in a semi-colon separated list.

Interrupt Method (SAML Class)

This method interrupts the current method.

Syntax

public void interrupt();

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

LoadIdentityMetadata Method (SAML Class)

Load an identity provider's metadata document.

Syntax

public void loadIdentityMetadata(String metadataDocument, boolean validate);

Remarks

This method loads in the identity provider's metadata document that is provided through the metadataDocument parameter. After the document has been loaded IdentityProviderEncryptingCert, IdentityProviderMetadata, IdentityProviderSigningCert and IdentityProviderURIs will be set with the information that is available in the document. If the metadata document is signed and the validate parameter is true, then the method will also validate the metadata document's signature.

ParseAssertion Method (SAML Class)

Parse and validate an assertion.

Syntax

public void parseAssertion(boolean validate);

Remarks

Parses and optionally validates the assertion found in the AssertionInfo property. The assertion can either be manually set by setting the AssertionContent field or by first calling ParseSAMLResponse on a SAMLResponse that contains an assertion. If the method is able to successful parse the assertion, the AssertionInfo property is populated along with the AssertionAttributeInfo and AssertionAuthnInfo collections once for each type of statement found in the assertion. Additionally, the method will fire the Assertion event before attempting validation (see below).

Validation:

If the validate parameter is set to true, then the method will attempt to validate the assertion. Before attempting this validation, theAssertion event provides an opportunity to configure the class to successfully validate the assertion. The following checks are performed on the assertion:


Validation Check	Required Property or Field
Signature	IdentityProviderSigningCert
Issuer Element	EntityId
InResponseTo Attribute	Id
Recipient Attribute	ServiceProviderURIs (ACS URI)
NotBefore Attribute	NA
NotOnOrAfter Attribute (Expiration Date)	NA
SessionNotOnOrAfter Attribute (Expiration Date)	NA

To skip certain checks, see AssertionValidationFlags.

ParseHTTPRequest Method (SAML Class)

Parse the current HTTP request.

Syntax

public void parseHTTPRequest(Object request);

Remarks

This method parses the current HTTP request and if found sets the ResponseContent field with the SAMLResponse. If a RelayState parameter is found in the request, it will be set to the RelayState property. The HTTP Request is taken directly from the HTTPRequestHeaders and HTTPRequest properties if set, otherwise it will try to read the HTTP context.

This method does not parse or validate the SAMLResponse. See the ParseSAMLResponse method for more information. To automatically parse and validate the SAMLResponse, see the ProcessHTTPRequest method.

ParseSAMLResponse Method (SAML Class)

Parse and validate a SAMLResponse.

Syntax

public void parseSAMLResponse(boolean validate);

Remarks

Parses and optionally validates the SAMLResponse found in the SAMLResponseInfo property. The SAMLResponse can either be manually set by setting the ResponseContent field or by first calling ParseHTTPRequest on an HTTP request with a SAMLResponse. If the method is able to successful parse the SAMLResponse, the information fields in the SAMLResponseInfo property is populated. Additionally, if the ResponseType is srtAuthn then the AssertionContent field is set. See ParseAssertion for more info on parsing and validating the assertion. Additionally, the method will fire the SAMLResponse event before attempting validation (see below).

Validation:

If the validate parameter is set to true, then the method will attempt to validate the SAMLResponse. Before attempting this validation, the SAMLResponse event provides an opportunity to configure the class to successfully validate the SAMLResponse. The following checks are performed on the SAMLResponse:


Validation Check	Property or Field
Signature (If Found)	IdentityProviderSigningCert
Issuer Element	EntityId
InResponseTo Attribute	Id
Destination Attribute	ServiceProviderURIs (ACS URI)
Status Element	NA

To skip certain checks, see SAMLResponseValidationFlags.

ProcessHTTPRequest Method (SAML Class)

Process the current HTTP Request.

Syntax

public void processHTTPRequest(Object request);

Remarks

Parses the current HTTP request and if applicable parses and validates the SAMLResponse and optional Assertion from the request. The method is the equivalent to calling the following methods. See the specific methods for more information.

ParseHTTPRequest
ParseSAMLResponse (validate = true)
ParseAssertion (validate = true)

The HTTP Request is taken directly from the HTTPRequestHeaders and HTTPRequest properties if set, otherwise it will try to read the HTTP context.

RequestIdentityMetadata Method (SAML Class)

Request an identity provider's SAML metadata document.

Syntax

public void requestIdentityMetadata(String URL);

Remarks

This method Makes an HTTP Get request to get the Identity Provider metadata document from the URL location. Once the document has been retrieved, the method will parse and validate the metadata document. After the document has been parsed the IdentityProviderEncryptingCert, IdentityProviderMetadata, IdentityProviderSigningCert and IdentityProviderURIs properties will be set with the information that is available in the document.

Reset Method (SAML Class)

This method will reset the class.

Syntax

public void reset();

Remarks

This method will reset the class's properties to their default values.

Assertion Event (SAML Class)

Fired when an assertion is parsed.

Syntax

public class DefaultSAMLEventListener implements SAMLEventListener {
  ...
  public void assertion(SAMLAssertionEvent e) {}
  ...
}

public class SAMLAssertionEvent {
  public String issuer;
  public String inResponseTo;
}

Remarks

This event is fired when an assertion is parsed but before the assertion is validated if it is being validated. The Issuer parameter is the Id of the entity that issued the assertion. The InResponseTo parameter is the Id of the SAMLRequest that requested the assertion. Note that these two parameters are what are found in the assertion and not what are set in the EntityId and Id fields respectively. This event allows certain settings to be set before the validation checks happen to ensure the assertion is correctly validated. See ParseAssertion for more information about the validation process.

EndTransfer Event (SAML Class)

This event is fired when a document finishes transferring.

Syntax

public class DefaultSAMLEventListener implements SAMLEventListener {
  ...
  public void endTransfer(SAMLEndTransferEvent e) {}
  ...
}

public class SAMLEndTransferEvent {
  public int direction;
}

Remarks

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

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

Error Event (SAML Class)

Fired when information is available about errors during data delivery.

  public void error(SAMLErrorEvent e) {}
  ...
}

public class SAMLErrorEvent {
  public int errorCode;
  public String description;
}

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class throws an exception.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

Header Event (SAML Class)

This event is fired every time a header line comes in.

Syntax

public class DefaultSAMLEventListener implements SAMLEventListener {
  ...
  public void header(SAMLHeaderEvent e) {}
  ...
}

public class SAMLHeaderEvent {
  public String field;
  public String value;
}

Remarks

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

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

Log Event (SAML Class)

Syntax

public class DefaultSAMLEventListener implements SAMLEventListener {
  ...
  public void log(SAMLLogEvent e) {}
  ...
}

public class SAMLLogEvent {
  public int logLevel;
  public String message;
  public String logType;
}

Remarks

This event fires once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.

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


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

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

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

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

Message is the log entry.

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

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

Redirect Event (SAML Class)

This event is fired when a redirection is received from the server.

Syntax

public class DefaultSAMLEventListener implements SAMLEventListener {
  ...
  public void redirect(SAMLRedirectEvent e) {}
  ...
}

public class SAMLRedirectEvent {
  public String location;
  public boolean accept; //read-write
}

Remarks

This event is fired in cases in which the client can decide whether or not to continue with the redirection process. The Accept parameter is always True by default, but if you do not want to follow the redirection, Accept may be set to False, in which case the class throws an exception. Location is the location to which the client is being redirected. Further control over redirection is provided in the FollowRedirects property.

SAMLResponse Event (SAML Class)

Fired when a SAMLResponse is parsed.

Syntax

public class DefaultSAMLEventListener implements SAMLEventListener {
  ...
  public void SAMLResponse(SAMLSAMLResponseEvent e) {}
  ...
}

public class SAMLSAMLResponseEvent {
  public String issuer;
  public String inResponseTo;
}

Remarks

This event is fired when an SAMLResponse is parsed but before the SAMLResponse is validated if it is being validated. The Issuer parameter is the Id of the entity that issued the SAMLResponse. The InResponseTo parameter is the Id of the SAMLRequest that requested the SAMLResponse. Note that these two parameters are what are found in the SAMLResponse and not what are set in the EntityId and Id fields respectively. This event allows certain settings to be set before the validation checks happen to ensure the SAMLResponse is correctly validated. See ParseSAMLResponse for more information about the validation process.

SetCookie Event (SAML Class)

This event is fired for every cookie set by the server.

Syntax

public class DefaultSAMLEventListener implements SAMLEventListener {
  ...
  public void setCookie(SAMLSetCookieEvent e) {}
  ...
}

public class SAMLSetCookieEvent {
  public String name;
  public String value;
  public String expires;
  public String domain;
  public String path;
  public boolean secure;
}

Remarks

The SetCookie event is fired for every Set-Cookie: header received from the HTTP server.

The Name parameter contains the name of the cookie, with the corresponding value supplied in the Value parameter.

The Expires parameter contains an expiration time for the cookie (if provided by the server). The time format used is "Weekday, DD-Mon-YY HH:MM:SS GMT". If the server does not provide an expiration time, the Expires parameter will be an empty string. In this case, the convention is to drop the cookie at the end of the session.

The Domain parameter contains a domain name to limit the cookie to (if provided by the server). If the server does not provide a domain name, the Domain parameter will be an empty string. The convention in this case is to use the server specified in the URL (URLServer) as the cookie domain.

The Path parameter contains a path name to limit the cookie to (if provided by the server). If the server does not provide a cookie path, the Path parameter will be an empty string. The convention in this case is to use the path specified in the URL (URLPath) as the cookie path.

The Secure parameter specifies whether the cookie is secure. If the value of this parameter is True, the cookie value must be submitted only through a secure (HTTPS) connection.

SSLServerAuthentication Event (SAML Class)

Fired after the server presents its certificate to the client.

Syntax

public class DefaultSAMLEventListener implements SAMLEventListener {

  public void SSLServerAuthentication(SAMLSSLServerAuthenticationEvent e) {}
  ...
}

public class SAMLSSLServerAuthenticationEvent {
  public byte[] certEncoded;
  public String certSubject;
  public String certIssuer;
  public String status;
  public boolean accept; //read-write
}

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 (SAML Class)

Fired when secure connection progress messages are available.

Syntax

public class DefaultSAMLEventListener implements SAMLEventListener {
  ...
  public void SSLStatus(SAMLSSLStatusEvent e) {}
  ...
}

public class SAMLSSLStatusEvent {
  public String message;
}

Remarks

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

  ...
  public void startTransfer(SAMLStartTransferEvent e) {}
  ...
}

public class SAMLStartTransferEvent {
  public int direction;
}

Remarks

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

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

Transfer Event (SAML Class)

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

Syntax

public class DefaultSAMLEventListener implements SAMLEventListener {
  ...
  public void transfer(SAMLTransferEvent e) {}
  ...
}

public class SAMLTransferEvent {
  public int direction;
  public long bytesTransferred;
  public int percentDone;
  public byte[] text;
}

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.

Store
String
Default Value: "MY"

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

The StoreType field denotes the type of the certificate store specified by Store. If the store is password protected, specify the password in StorePassword.

Store is used in conjunction with the Subject field to specify client certificates. If Store has a value, and Subject or Encoded is set, a search for a certificate is initiated. Please see the Subject field for details.

Designations of certificate stores are platform dependent.

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


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

In Java, the certificate store normally is a file containing certificates and optional private keys.

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).

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.

In Java, the certificate store normally is a file containing certificates and optional private keys.

StorePassword
String
Default Value: ""

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

StoreType
int
Default Value: 0

This is the type of certificate store for this certificate.

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


0 (cstUser - default)	For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: This store type is not available in Java.
1 (cstMachine)	For Windows, this specifies that the certificate store is a machine store. Note: This store type is not available in Java.
2 (cstPFXFile)	The certificate store is the name of a PFX (PKCS#12) file containing certificates.
3 (cstPFXBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) format.
4 (cstJKSFile)	The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: This store type is only available in Java.
5 (cstJKSBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: This store type is only available in Java.
6 (cstPEMKeyFile)	The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)	The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)	The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)	The certificate store is a string (binary or Base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)	The certificate store is a string (binary or Base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)	The certificate store is the name of a PKCS#7 file containing certificates.
12 (cstP7BBlob)	The certificate store is a string (binary) representing a certificate store in PKCS#7 format.
13 (cstSSHPublicKeyFile)	The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)	The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)	The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 (cstXMLFile)	The certificate store is the name of a file that contains a certificate in XML format.
17 (cstXMLBlob)	The certificate store is a string that contains a certificate in XML format.
18 (cstJWKFile)	The certificate store is the name of a file that contains a JWK (JSON Web Key).
19 (cstJWKBlob)	The certificate store is a string that contains a JWK (JSON Web Key).

22 (cstBCFKSBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: This store type is only available in Java and .NET.
23 (cstPKCS11)	The certificate is present on a physical security key accessible via a PKCS#11 interface. To use a security key, the necessary data must first be collected using the CERTMGR class. The ListStoreCertificates method may be called after setting CertStoreType to `cstPKCS11`, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's `CertEncoded` parameter may be saved for later use. When using a certificate, pass the previously saved security key information as the Store and set StorePassword to the PIN. Code Example. SSH Authentication with Security Key: `certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);`
99 (cstAuto)	The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

EncodedB
byte[]
Default Value: ""

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

Constructors

public Certificate();

Creates a instance whose properties can be set. This is useful for use with when generating new certificates.

public Certificate( certificateFile);

Opens CertificateFile and reads out the contents as an X.509 public key.

public Certificate( encoded);

Parses Encoded as an X.509 public key.

public Certificate( storeType,  store,  storePassword,  subject);

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

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

public Certificate( storeType,  store,  storePassword,  subject,  configurationString);

ConfigurationString is a newline separated list of name-value pairs that may be used to modify the default behavior. Possible values include "PersistPFXKey", which shows whether or not the PFX key is persisted after performing operations with the private key. This correlates to the PKCS12_NO_PERSIST_KEY CryptoAPI option. The default value is True (the key is persisted). "Thumbprint" - an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load. When specified, this value is used to select the certificate in the store. This is applicable to the cstUser , cstMachine , cstPublicKeyFile , and cstPFXFile store types. "UseInternalSecurityAPI" shows whether the platform (default) or the internal security API is used when performing certificate-related operations.

public Certificate( storeType,  store,  storePassword,  encoded);

After the store has been successfully opened, the class will load Encoded as an X.509 certificate and search the opened store for a corresponding private key.

public Certificate( storeType,  store,  storePassword,  subject);

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

public Certificate( storeType,  store,  storePassword,  subject,  configurationString);

public Certificate( storeType,  store,  storePassword,  encoded);

After the store has been successfully opened, the class will load Encoded as an X.509 certificate and search the opened store for a corresponding private key.

When set to false (default) the Identity Provider should only issue an assertion if an acceptable identifier is already created.

Consent
int
Default Value: 0

If consent from a principle was provided in the sending of this request. This typically is set to some URI reference that was used by the application to obtain consent from the principal (user). This setting specifically sets the Consent attribute in the AuthnRequest or LogoutRequest elements in a SAMLRequest.

By default, the scidUnspecified value is used. If a format needs to be used that is not listed here, the snidCustom value can be used instead. When set, the SAMLRequestCustomConsent configuration setting will be used instead.

Id
String
Default Value: ""

This field is a unique Id of the SAMLRequest. If left empty before calling BuildAuthnRequest or BuildLogoutRequest, the class will automatically generate an Id. This Id should match the Id of the InResponseTo attribute the matching SAMLResponse (see InResponseTo for more information).

IssuedTime
String
Default Value: ""

This field is the time that the SAMLRequest was issued. If not set, the class will use the current time.

Time based values are specified by the SAML specification to be a UTC encoded value in the following format.

YYYY-MM-DDTHH:mm:ss.sssZ

Issuer
String
Default Value: ""

This field is the issuer of the SAMLRequest. If left blank, the class will use the value EntityId field.

NameIdFormat
int
Default Value: 0

If supported by the Identity Provider, this setting can be used to tailor the name identifier for the subject in the response to an Authn Request. For Logout Requests this field is not used.

By default, the snidUnspecified format will be used which informs the Identity Provider to use whatever name identifier format they prefer. This setting specifically sets the Format attribute in the NameIDPolicy element in an AuthnRequest. If a format needs to be used that is not listed here, the snidCustom value can be used instead. When set, the SAMLRequestCustomNameIdFormat configuration setting will be used instead.

99 (snidCustom)	Custom Format	NA

RequestBinding
int
Default Value: 0

The binding that will be used to make the request.

By default, the component will use the srbHTTPRedirect binding which provides the SAMLRequest through a query parameter. The srbHTTPRedirect binding will set just the SAMLRequestURL property.

If set to the srbHTTPPost binding, the SAMLResponse is provided in a HTML body that should be used to make a form post request to. This will set both the SAMLRequestURL and SAMLRequestBody properties.


Value	BindingName	Binding URI
0 (srbHTTPRedirect - default)	HTTP Redirect Binding	`urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect`
1 (srbHTTPPost)	HTTP Post Binding	`urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST`

SelectedEndpoint
int
Default Value: -1

This setting only applies to Authn Requests since there can be multiple Assertion Consumer Service (ACS) endpoints per service provider. When building an Authn Request, by default, the class will select the first ACS endpoint available in the ServiceProviderURIs collection. If set to a positive integer, then the class will search the ServiceProviderURIs collection for a URI with the appropriate BindingType and Index settings.

If the class cannot find an endpoint with a matching Index, then it will select the URI with the IsDefault field set. If no URIs are set with the IsDefault field, then the class will select the first URI with the correct BindingType.

If UseDefaultEndpoint is set to true, then this field will not do anything.

SignRequest
boolean
Default Value: False

This setting should be set to true if the SAMLRequest should be signed when building the SAMLRequest using the BuildAuthnRequest or BuildLogoutRequest methods. The class will use the certificate set in the ServiceProviderSigningCert property to sign the request.

UseDefaultEndpoint
boolean
Default Value: False

This setting only applies to Authn Requests since there can be multiple Assertion Consumer Service (ACS) endpoints per service provider. When multiple ACS endpoints are available, a single endpoint can be selected as the default endpoint. When this setting is set to true, the class will select the first URI with the correct BindingType that also has the IsDefault field set when building an Authn Request.

This field provides the message that was provided in the status of the SAMLResponse. This setting is alongside the StatusCodes and can be used to provide more information about the status.

Constructors

public SAMLResponseInfo();

ServiceProviderMetadata Type

The metadata settings for a service provider.

Remarks

The metadata settings for a service provider. This is typically used when configuring an Identity Provider with the information about your application.

The following fields are available:

SupportedNameIdFormats

WantAssertionsSigned

Fields

AuthnRequestSigned
boolean
Default Value: False

When this field is set to true, the generated metadata document will inform the identity provider that this service provider will be sending signed requests.

EntityId
String
Default Value: ""

This field should be set to the Entity Id for this service provider. This is the unique Id that will be used by the Identity Provider and should be unique to this service provider.

String
Default Value: ""

The raw XML document that represents the metadata document for the configured service provider. This field is populated when the BuildServiceMetadata method is used to generate a new document.

MetadataContentB
byte[]
Default Value: ""

The raw XML document that represents the metadata document for the configured service provider. This field is populated when the BuildServiceMetadata method is used to generate a new document.

SignedMetadata
boolean
Default Value: False

If this field is set to true, then the class will sign the metadata document when it is being generated. The class when the BuildServiceMetadata method is used to generate the metadata document, it will use the ServiceProviderSigningCert property to sign the document.

SupportedNameIdFormats
String
Default Value: ""

A semi-colon separated list of NameId formats that are supported by this service provider. Some common values are:


`urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified`	Unspecified
`urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress`	Email Address
`urn:oasis:names:tc:SAML:1.1:nameid-format:WindowsDomainQualifiedName`	Windows Domain Qualified Name

To support both email addresses and Windows domain qualified name, this field would then be set to:

urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress;urn:oasis:names:tc:SAML:1.1:nameid-format:WindowsDomainQualifiedName

WantAssertionsSigned
boolean
Default Value: False

If this field is set to true, the metadata document inform the identity provider that this service provider wants issued assertions to be signed.

Constructors

public ServiceProviderMetadata();

URI Type

A URI endpoint that is used in the SAML protocol.

Remarks

A URI endpoint that is used in the SAML protocol. Service providers and identity providers provide information about what URI should be used when making specific requests.

The following fields are available:

Fields

BindingRef
String
Default Value: ""

This field holds the URI reference for the set BindingType. When the BindingType is set, this field will be updated to match. The exception is the subCustom value which allows for any value to be placed in this field.

If instead this field is set, then the class will attempt to set the BindingType field to match. If it can't, then the subCustom will also be used.

When parsing a metadata document, the class will also used the subCustom value for any binding types that are not recognized by the class.

BindingType
int
Default Value: 0

This field represents the type of binding that is supported for this URI. The class only supports using the HTTP Redirect and HTTP Post bindings. The HTTP Artifact and other bindings are informational and support for them must be implemented directly.

When setting this field, the BindingRef field will also be updated with the matching URI. The exception is the subCustom value which allows for any value to be placed in the BindingRef field.

If the BindingRef field is set or during the processing of a metadata document, the class will attempt to set this field as well with the matching value. If it can't then subCustom will be used instead.


Value	Binding Name	Identifier URI
00 (subRedirect - default)	HTTP Redirect	`urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect`
01 (subPost)	HTTP POST	`urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST`
02 (subArtifact - unsupported)	HTTP Artifact	`urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Artifact`
99 (subCustom)	Custom Format	NA

Index
int
Default Value: 0

This field represents the index for the URI that can be optionally used if multiple URIs of the same URIType and BindingType are provided.

IsDefault
boolean
Default Value: False

If this field is set to true, then this URI is the default URI that should be used for the specific URIType and BindingType combination.

Location
String
Default Value: ""

This field is set to the address of the URI.

URIType
int
Default Value: 0

This field is set to the purpose of the URI. Possible values are:


0 (sutSignon - default)	Identity Provider	Single Sign-on URI
1 (sutLogout)	Both	Logout URI
2 (sutACS)	Service Provider	Assertion Consumer Service

Constructors

public URI();

Config Settings (SAML Class)

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

SAML Config Settings

AssertionValidationFlags: The checks that are ignored when validating an Assertion.

Informs that class to skip certain checks when validating a parsed Assertion. The following flags are defined (specified in hexadecimal notation). They can be or-ed together to exclude multiple conditions:


0x00000001	Ignore the SubjectConfirmation element.
0x00000002	Ignore the AuthnStatement element.
0x00000004	Ignore the Issuer element.
0x00000008	Ignore the Assertion's signature. (Does not apply to the SAMLResponse).
0x00000010	Ignores a mismatch between the certificates set to the class and the one found in the signature of the Assertion.
0x00000020	Ignores the Conditions element.

AttributeNameProfile: The set of names that are used for common attributes.

This setting takes a semi-colon separated list supported names for attributes when setting the UserInfo* fields in the AssertionInfo property. For example microsoft;basic would be a list that enabled just the Azure and Basic profiles. The class will check in order for each enabled profile. By default, all the profiles below are enabled.


`basic`	The basic names for the attributes.
`microsoft`	The scheme used by Microsoft Entra.

SAMLRequestCustomConsent: TBD.

TBD.

SAMLRequestCustomNameIdFormat: TBD.

TBD.

SAMLRequestSPNameQualifier: TBD.

TBD.

SAMLResponseValidationFlags: The checks that are ignored when validating a SAMLResponse.

Informs that class to skip certain checks when validating a parsed SAMLResponse. The following flags are defined (specified in hexadecimal notation). They can be or-ed together to exclude multiple conditions:


0x00000001	Ignore the InResponseTo attribute.
0x00000002	Ignore the destination attribute.
0x00000004	Ignore the Issuer element.
0x00000008	Ignore the SAMLResponse's signature. (Does not apply to the Assertion).
0x00000010	Ignores a mismatch between the certificates set to the class and the one found in the signature of the SAMLResponse.
0x00000020	Ignores a status that is not set to a success.

HTTP Config Settings

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

When AllowHTTPCompression is True, the class adds an Accept-Encoding header to the request being sent to the server. By default, this header's value is "gzip, deflate". This configuration setting allows you to change the value of the Accept-Encoding header. Note: The class only supports gzip and deflate decompression algorithms.

AllowHTTPCompression: This property enables HTTP compression for receiving data.

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

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

The default value is True.

AllowHTTPFallback: Whether HTTP/2 connections are permitted to fallback to HTTP/1.1.

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

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

The default value is True.

AllowNTLMFallback: Whether to allow fallback from Negotiate to NTLM when authenticating.

This configuration setting applies only when AuthScheme is set to Negotiate. If set to True, the class will automatically use New Technology LAN Manager (NTLM) if the server does not support Negotiate authentication. Note: The server must indicate that it supports NTLM authentication through the WWW-Authenticate header for the fallback from Negotiate to NTLM to take place. The default value is False.

Append: Whether to append data to LocalFile.

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

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

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

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

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

BytesTransferred: Contains the number of bytes transferred in the response data.

This configuration setting returns the raw number of bytes from the HTTP response data, before the component processes the data, whether it is chunked or compressed. This returns the same value as the Transfer event, by BytesTransferred.

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

This is applicable only when UseChunkedEncoding is True. This setting specifies the chunk size in bytes to be used when posting data. The default value is 16384.

CompressHTTPRequest: Set to true to compress the body of a PUT or POST request.

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

The default value is False.

EncodeURL: If set to True the URL will be encoded by the class.

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

FollowRedirects: Determines what happens when the server issues a redirect.

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

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

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.

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

Following are the valid options:

0 - Never
1 - Always
2 - Same Scheme

GetOn302Redirect: If set to True the class will perform a GET on the new location.

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

HTTP2HeadersWithoutIndexing: HTTP2 headers that should not update the dynamic header table with incremental indexing.

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

HTTPVersion: The version of HTTP used by the class.

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

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

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

HTTP/2 Notes

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

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

HTTP/2 is supported on all platforms. The class will use the internal security implementation in all cases when connecting.

HTTP/3 Notes

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

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

IfModifiedSince: A date determining the maximum age of the desired document.

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

The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example: Sat, 29 Oct 2017 19:43:31 GMT.

KeepAlive: Determines whether the HTTP connection is closed after completion of the request.

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

The default value for KeepAlive is false.

KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.

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

LogLevel: The level of detail that is logged.

This configuration setting controls the level of detail that is logged through the Log event. Possible values are as follows:


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

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

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

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

MaxHeaders: Instructs class to save the amount of headers specified that are returned by the server after a Header event has been fired.

This configuration setting should be set when the TransferredHeaders collection is to be populated when a Header event has been fired. This value represents the number of headers that are to be saved in the collection.

To save all items to the collection, set this configuration setting to -1. If no items are wanted, set this to 0, which will not save any items to the collection. The default for this configuration setting is -1, so all items will be included in the collection.

MaxHTTPCookies: Instructs class to save the amount of cookies specified that are returned by the server when a SetCookie event is fired.

This configuration setting should be set when populating the Cookies collection as a result of an HTTP request. This value represents the number of cookies that are to be saved in the collection.

MaxRedirectAttempts: Limits the number of redirects that are followed in a request.

When FollowRedirects is set to any value other than frNever, the class will follow redirects until this maximum number of redirect attempts are made. The default value is 20.

NegotiatedHTTPVersion: The negotiated HTTP version.

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

OtherHeaders: Other headers as determined by the user (optional).

This configuration setting can be set to a string of headers to be appended to the HTTP request headers.

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

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

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

ProxyAuthorization: The authorization string to be sent to the proxy server.

This is similar to the Authorization configuration setting, but is used for proxy authorization. If this configuration setting contains a nonempty string, a Proxy-Authorization HTTP request header is added to the request. This header conveys proxy Authorization information to the server. If User and Password are specified, this value is calculated using the algorithm specified by AuthScheme.

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

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

ProxyPassword: A password if authentication is to be used for the proxy.

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

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

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

ProxyServer: Name or IP address of a proxy server (optional).

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

ProxyUser: A user name if authentication is to be used for the proxy.

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

SentHeaders: The full set of headers as sent by the client.

This configuration setting returns the complete set of raw headers as sent by the client.

StatusCode: The status code of the last response from the server.

This configuration setting contains the result code of the last response from the server.

StatusLine: The first line of the last response from the server.

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

TransferredData: The contents of the last response from the server.

This configuration setting contains the contents of the last response from the server.

TransferredDataLimit: The maximum number of incoming bytes to be stored by the class.

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

TransferredHeaders: The full set of headers as received from the server.

This configuration setting returns the complete set of raw headers as received from the server.

TransferredRequest: The full request as sent by the client.

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

.NET Http http = new Http(); http.Config("TransferredRequest=on"); http.PostData = "body"; http.Post("http://someserver.com"); Console.WriteLine(http.Config("TransferredRequest")); C++ HTTP http; http.Config("TransferredRequest=on"); http.SetPostData("body", 5); http.Post("http://someserver.com"); printf("%s\r\n", http.Config("TransferredRequest"));

UseChunkedEncoding: Enables or Disables HTTP chunked encoding for transfers.

If UseChunkedEncoding is set to True, the class will use HTTP-chunked encoding when posting, if possible. HTTP-chunked encoding allows large files to be sent in chunks instead of all at once. If set to False, the class will not use HTTP-chunked encoding. The default value is False.

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

UseIDNs: Whether to encode hostnames to internationalized domain names.

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

The default value is False and the hostname will always be used exactly as specified.

UsePlatformDeflate: Whether to use the platform implementation to decompress compressed responses.

This configuration setting specifies whether the platform's deflate-algorithm implementation is used to decompress responses that use compression. If set to True (default), the platform implementation is used. If set to False, an internal implementation is used.

UsePlatformHTTPClient: Whether or not to use the platform HTTP client.

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

UseProxyAutoConfigURL: Whether to use a Proxy auto-config file when attempting a connection.

This configuration specifies whether the class will attempt to use the Proxy auto-config URL when establishing a connection and AutoDetect 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

CloseStreamAfterTransfer: If true, the component will close the upload or download stream after the transfer.

This configuration setting determines whether the input or output stream is closed after the transfer completes. When set to True (default), all streams will be closed after a transfer is completed. To keep streams open after the transfer of data, set this to False. The default value is True.

ConnectionTimeout: Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the class will use Timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect: Tells the class whether or not to automatically detect and use firewall system settings, if available.

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

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

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

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

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

FirewallListener: If true, the component binds to a SOCKS firewall as a server (TCPClient only).

This entry is for TCPClient only and does not work for other components that descend from TCPClient.

If this entry is set, the class acts as a server. RemoteHost and RemotePort are used to tell the SOCKS firewall in which address and port to listen to. The firewall rules may ignore RemoteHost, and it is recommended that RemoteHost be set to empty string in this case.

RemotePort is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The binding (address and port) is provided through the ConnectionStatus event.

The connection to the firewall is made by calling the Connect method.

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

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the class throws an exception.

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

FirewallPort: The TCP port for the FirewallHost;.

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

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

FirewallType: Determines the type of firewall to connect through.

The appropriate values are as follows:


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

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

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

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the class throws an exception.

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

KeepAliveInterval: The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

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

Note: This value is not applicable in macOS.

KeepAliveTime: The inactivity time in milliseconds before a TCP keep-alive packet is sent.

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

Linger: When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

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

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

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

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

LingerTime: Time in seconds to have the connection linger.

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

LocalHost: The name of the local host through which connections are initiated or accepted.

The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In 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 classs) only through that interface.

If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for 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 is the size of an internal buffer, which holds received data while waiting for an EOL string.

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

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

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate: The transfer rate limit in bytes per second.

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

ProxyExceptionsList: A semicolon separated list of hosts and IPs to bypass when using a proxy.

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

www.google.com;www.nsoftware.com

TCPKeepAlive: Determines whether or not the keep alive socket option is enabled.

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

TcpNoDelay: Whether or not to delay when sending packets.

When 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 False and NTLM V1 will be used. Set this to True to use NTLM V2.

SSL Config Settings

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

When SSLProvider 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 event, which will fire each time an SSL packet is sent or received.

Enabling this configuration setting has no effect if SSLProvider is set to Platform.

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.

SSLCACerts: A newline separated list of CA certificates to be included when performing an SSL handshake.

When SSLProvider is set to Internal, this configuration setting specifies one or more CA certificates to be included with the SSLCert 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:

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

-----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 throws an exception.

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 throws an exception.

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 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 is currently not supported. This functionality is instead made available through the 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 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:

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

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

SSLContextProtocol: The protocol used when getting an SSLContext instance.

Possible values are SSL, SSLv2, SSLv3, TLS, and TLSv1. Use this configuration setting only in case your security provider does not support TLS. This is the parameter "protocol" inside the SSLContext.getInstance(protocol) call.

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

Multiple cipher suites are separated by semicolons.

Note: This value must be set after SSLProvider is set.

Example values: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA"); obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA; SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA"); Possible values when SSLProvider is set to Platform include the following:

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

TLS_AES_256_GCM_SHA384
TLS_CHACHA20_POLY1305_SHA256
TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

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

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 use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.

In editions that are designed to run on Windows, SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is 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 and other similar SSL configuration settings are not supported.
If 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 is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider 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 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 event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the SSLServerAuthentication event.

If set to True, all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

Note: When SSLProvider is set to Internal this value is automatically set to true. This is needed for proper validation when using the internal provider.

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 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: 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: 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.

SSLNegotiatedKeyExchange: Returns the negotiated key exchange algorithm.

This configuration setting returns the key exchange algorithm negotiated during the SSL handshake.

SSLNegotiatedKeyExchangeStrength: Returns the negotiated key exchange algorithm strength.

This configuration setting returns the strength of the key exchange algorithm negotiated during the SSL handshake.

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: server.Config("SSLNegotiatedVersion[connId]");

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 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:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw

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

SSLTrustManagerFactoryAlgorithm: The algorithm to be used to create a TrustManager through TrustManagerFactory.

Possible values include SunX509. This is the parameter "algorithm" inside the TrustManagerFactory.getInstance(algorithm) call.

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 is set to Internal and SSLEnabledProtocols is set to allow TLS 1.2.

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

The format of this value is a comma-separated list of hash-signature combinations. For instance: component.SSLProvider = TCPClientSSLProviders.sslpInternal; component.Config("SSLEnabledProtocols=3072"); //TLS 1.2 component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa"); The default value for this 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 is set to Internal, the values refer to the supported groups for ECC. The following values are supported:

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

TLS13KeyShareGroups: The groups for which to pregenerate key shares.

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

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

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

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

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

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

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

TLS13SignatureAlgorithms: The allowed certificate signature algorithms.

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

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

The default value is rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448. This configuration setting is applicable only when SSLEnabledProtocols 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

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

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

Socket Config Settings

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

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

Note: This option is not valid for 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.

GUIAvailable: Whether or not a message loop is available for processing events.

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The class will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the class does not attempt to process external events.

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.

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

UseDaemonThreads: Whether threads created by the class are daemon threads.

If set to True (default), when the class creates a thread, the thread's Daemon property will be explicitly set to True. When set to False, the class will not set the Daemon property on the created thread. The default value 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.
