HashAlgorithmType Enumeration

 

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

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

public enum HashAlgorithmType

Member nameDescription
Md5

The Message Digest 5 (MD5) hashing algorithm.

None

No hashing algorithm is used.

Sha1

The Secure Hashing Algorithm (SHA1).

Sha256

The Secure Hashing Algorithm 2 (SHA-2), using a 256-bit digest.

Sha384

The Secure Hashing Algorithm 2 (SHA-2), using a 384-bit digest.

Sha512

The Secure Hashing Algorithm 2 (SHA-2), using a 512-bit digest.

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;
    }
}
