SslStream.SslProtocol Property


Gets a value that indicates the security protocol used to authenticate this connection.

 virtual property System::Security::Authentication::SslProtocols SslProtocol { System::Security::Authentication::SslProtocols get(); };
public virtual System.Security.Authentication.SslProtocols SslProtocol { get; }
member this.SslProtocol : System.Security.Authentication.SslProtocols
Public Overridable ReadOnly Property SslProtocol As SslProtocols

Property Value

The SslProtocols value that represents protocols used for authentication.


The following example displays the security properties of the specified stream.

static void DisplaySecurityLevel( SslStream^ stream )
   Console::WriteLine( L"Cipher: {0} strength {1}", stream->CipherAlgorithm, stream->CipherStrength );
   Console::WriteLine( L"Hash: {0} strength {1}", stream->HashAlgorithm, stream->HashStrength );
   Console::WriteLine( L"Key exchange: {0} strength {1}", stream->KeyExchangeAlgorithm, stream->KeyExchangeStrength );
   Console::WriteLine( L"Protocol: {0}", stream->SslProtocol );
static void DisplaySecurityLevel(SslStream stream)
   Console.WriteLine("Cipher: {0} strength {1}", stream.CipherAlgorithm, stream.CipherStrength);
   Console.WriteLine("Hash: {0} strength {1}", stream.HashAlgorithm, stream.HashStrength);
   Console.WriteLine("Key exchange: {0} strength {1}", stream.KeyExchangeAlgorithm, stream.KeyExchangeStrength);
   Console.WriteLine("Protocol: {0}", stream.SslProtocol);
Private Shared Sub DisplaySecurityLevel(stream As SslStream)
    Console.WriteLine("Cipher: {0} strength {1}", stream.CipherAlgorithm, stream.CipherStrength)
    Console.WriteLine("Hash: {0} strength {1}", stream.HashAlgorithm, stream.HashStrength)
    Console.WriteLine("Key exchange: {0} strength {1}", stream.KeyExchangeAlgorithm, stream.KeyExchangeStrength)
    Console.WriteLine("Protocol: {0}", stream.SslProtocol)
End Sub


The enabled security protocols can be specified in AuthenticateAsClient or via EnabledSslProtocols and AuthenticateAsServer or EnabledSslProtocols. If no security protocol was explicitly specified, the Default value is used.

The actual protocol used for authentication is selected based on the ones supported by the client and server.
