SslStream.AuthenticateAsClientAsync Method (String, X509CertificateCollection, SslProtocols, Boolean)
Called by clients to authenticate the server and optionally the client in a client-server connection as an asynchronous operation. The authentication process uses the specified certificate collection and SSL protocol.
Assembly: System (in System.dll)
<HostProtectionAttribute(SecurityAction.LinkDemand, ExternalThreading := True)> Public Overridable Function AuthenticateAsClientAsync ( targetHost As String, clientCertificates As X509CertificateCollection, enabledSslProtocols As SslProtocols, checkCertificateRevocation As Boolean ) As Task
The X509CertificateCollection that contains client certificates.
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.
