public function get KeyExchangeStrength () : int

Property Value

An Int32 value that specifies the strength of the ExchangeAlgorithmType algorithm, in bits.

The value of this property is zero until the authentication occurs.

In common scenarios, the value of this property is one of the following:

  • 512

  • 768

  • 1024

  • 2048

The following code example displays the cryptography settings for 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);
