Called by servers to begin an asynchronous operation to authenticate the server and optionally the client using the specified certificates, requirements and security protocol.
- serverCertificate
- The X509Certificate used to authenticate the server.
- clientCertificateRequired
- A bool value that specifies whether the client must supply a certificate for authentication.
- enabledSslProtocols
- The System.Security.Authentication.SslProtocols value that represents the protocol used for authentication.
- checkCertificateRevocation
- A bool value that specifies whether the certificate revocation list is checked during authentication.
- asyncCallback
- An AsyncCallback delegate that references the method to invoke when the authentication is complete.
- asyncState
- A user-defined object that contains information about the operation. This object is passed to the asyncCallback delegate when the operation completes.
An IAsyncResult object that indicates the status of the asynchronous operation.
The asynchronous authentication operation must be completed by calling the SslStream.EndAuthenticateAsServer(IAsyncResult) method. Typically, the method is invoked by the asyncCallback delegate.
This method does not block while the operation completes. To block until the operation completes, use one of the erload:System.Net.Security.SslStream.AuthenticateAsServer method overloads.
For detailed information about using the asynchronous programming model, see Asynchronous Programming Overview
If you receive a System.Security.Authentication.AuthenticationException, this System.Net.Security.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.
