SslStream.SslProtocol Property

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

Namespace:  System.Net.Security
Assembly:  System (in System.dll)

public virtual SslProtocols SslProtocol { get; }

Property Value

Type: System.Security.Authentication.SslProtocols
The SslProtocols value that represents the protocol used for authentication.

The supported security protocols are specified when the SslStream is created. If no security protocol was passed to the constructor, the instance is created using Default. The actual protocol used for authentication is selected based on the protocols supported by the client and server.

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

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);
}
static void DisplaySecurityLevel(SslStream* stream)
{
    Console::WriteLine(S"Cipher: {0} strength {1}", __box(stream->CipherAlgorithm), __box(stream->CipherStrength));
    Console::WriteLine(S"Hash: {0} strength {1}", __box(stream->HashAlgorithm), __box(stream->HashStrength));
    Console::WriteLine(S"Key exchange: {0} strength {1}", __box(stream->KeyExchangeAlgorithm), __box(stream->KeyExchangeStrength));
    Console::WriteLine(S"Protocol: {0}", __box(stream->SslProtocol));
