SslStream.AuthenticateAsServerAsync Method (X509Certificate)
Called by servers to authenticate the server and optionally the client in a client-server connection using the specified certificate as an asynchronous operation.
Assembly: System (in System.dll)
[<HostProtectionAttribute(SecurityAction.LinkDemand, ExternalThreading = true)>] abstract AuthenticateAsServerAsync : serverCertificate:X509Certificate -> Task [<HostProtectionAttribute(SecurityAction.LinkDemand, ExternalThreading = true)>] override AuthenticateAsServerAsync : serverCertificate:X509Certificate -> Task
- Type: System.Security.Cryptography.X509Certificates.X509Certificate
The certificate used to authenticate the server.
serverCertificate is a null reference (Nothing in Visual Basic).
The authentication failed and left this object in an unusable state.
Authentication has already occurred.
Client authentication using this SslStream was tried previously.
Authentication is already in progress.
This object has been closed.
The AuthenticateAsServerAsync method is not supported on Windows 95, Windows 98, or Windows Millennium.
This method authenticates using Default. The certificate revocation list is not checked during authentication. The client is not required to provide a certificate for authentication.
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.
The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: ExternalThreading. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser).
