HashAlgorithmType Enumeration

Note: This enumeration is new in the .NET Framework version 2.0.

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

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

public enum HashAlgorithmType
public enum HashAlgorithmType
public enum HashAlgorithmType
 Member nameDescription
Md5The Message Digest 5 (MD5) hashing algorithm. 
NoneNo hashing algorithm is used. 
Sha1The Secure Hashing Algorithm (SHA1). 

This enumeration specifies valid values for the SslStream.HashAlgorithm property.

The following example displays the properties of an SslStream after authentication has succeeded.

static void AuthenticateCallback(IAsyncResult ar)
{
    SslStream stream = (SslStream) ar.AsyncState;
    try 
    {
        stream.EndAuthenticateAsClient(ar);
        Console.WriteLine("Authentication succeeded.");
        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);
        // Encode a test message into a byte array.
        // Signal the end of the message using the "<EOF>".
        byte[] message = Encoding.UTF8.GetBytes("Hello from the client.<EOF>");
        // Asynchronously send a message to the server.
        stream.BeginWrite(message, 0, message.Length, 
            new AsyncCallback(WriteCallback),
            stream);
    }
    catch (Exception authenticationException)
    {
        e = authenticationException;
        complete = true;
        return;
    }
}
