SslStream.AuthenticateAsClient Method (String, X509CertificateCollection, SslProtocols, Boolean)
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.
Assembly: System (in System.dll)
public virtual void AuthenticateAsClient( string targetHost, X509CertificateCollection clientCertificates, SslProtocols enabledSslProtocols, bool checkCertificateRevocation )
- Type: System.Security.Cryptography.X509Certificates.X509CertificateCollection
The X509CertificateCollection that contains client certificates.
- Type: System.Security.Authentication.SslProtocols
The SslProtocols value that represents the protocol used for 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.
Client certificates are not supported in the SSL version 2 protocol.
