CipherAlgorithmType Enumeration

CipherAlgorithmType Enumeration

 

Defines the possible cipher algorithms for the SslStream class.

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

public enum CipherAlgorithmType

Member nameDescription
Aes

The Advanced Encryption Standard (AES) algorithm.

Aes128

The Advanced Encryption Standard (AES) algorithm with a 128 bit key.

Aes192

The Advanced Encryption Standard (AES) algorithm with a 192 bit key.

Aes256

The Advanced Encryption Standard (AES) algorithm with a 256 bit key.

Des

The Data Encryption Standard (DES) algorithm.

None

No encryption algorithm is used.

Null

No encryption is used with a Null cipher algorithm.

Rc2

Rivest's Code 2 (RC2) algorithm.

Rc4

Rivest's Code 4 (RC4) algorithm.

TripleDes

The Triple Data Encryption Standard (3DES) algorithm.

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

The following example displays the properties of an SslStream.

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;
    }
}
