HashAlgorithmType Enumeration
Specifies the algorithm used for generating message authentication codes (MACs).
Assembly: System (in System.dll)
| Member name | Description | |
|---|---|---|
| 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; } }
