SslStream.HashAlgorithm Property

Gets the algorithm used for generating message authentication codes (MACs).

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

public virtual HashAlgorithmType HashAlgorithm { get; }
/** @property */
public HashAlgorithmType get_HashAlgorithm ()

public function get HashAlgorithm () : HashAlgorithmType

Not applicable.

Property Value

A HashAlgorithmType value.

Exception typeCondition

InvalidOperationException

The HashAlgorithm property was accessed before the completion of the authentication process or the authentication process failed.

Message authentication algorithms generate message hashes and signatures used to detect tampering and forgery.

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);
}
