AuthenticateAsClient Method (String, X509CertificateCollection, SslProtocols, Boolean)

SslStream.AuthenticateAsClient Method (String, X509CertificateCollection, SslProtocols, Boolean)

Note: This method is new in the .NET Framework version 2.0.

Called by clients to authenticate the server and optionally the client in a client-server connection. The authentication process uses the specified certificate collection and SSL protocol.

Namespace: System.Net.Security
Assembly: System (in system.dll)

public virtual void AuthenticateAsClient (
	string targetHost,
	X509CertificateCollection clientCertificates,
	SslProtocols enabledSslProtocols,
	bool checkCertificateRevocation
)
public void AuthenticateAsClient (
	String targetHost, 
	X509CertificateCollection clientCertificates, 
	SslProtocols enabledSslProtocols, 
	boolean checkCertificateRevocation
)
public function AuthenticateAsClient (
	targetHost : String, 
	clientCertificates : X509CertificateCollection, 
	enabledSslProtocols : SslProtocols, 
	checkCertificateRevocation : boolean
)

Parameters

targetHost

The name of the server that will share this SslStream.

clientCertificates

The X509CertificateCollection that contains client certificates.

enabledSslProtocols

The SslProtocols value that represents the protocol used for authentication.

checkCertificateRevocation

A Boolean value that specifies whether the certificate revocation list is checked during authentication.

When authentication succeeds, you must check the IsEncrypted and IsSigned properties to determine what security services are used by the SslStream. Check the IsMutuallyAuthenticated property to determine whether mutual authentication occurred.

If the authentication fails, you receive a AuthenticationException, and this SslStream is no longer useable. You should close this object and remove all references to it so that it can be collected by the garbage collector.

NoteNote

Client certificates are not supported in the SSL version 2 protocol.
