abstract class

public abstract class TripleDES : SymmetricAlgorithm { // Public Constructors    public TripleDES(  ); // Public Instance Properties    public override byte[  ] Key{set; get;  // overrides SymmetricAlgorithm // Public Static Methods    public static TripleDES Create(  );    public static TripleDES Create(string str);    public static bool IsWeakKey(byte[  ] rgbKey); }

This class extends SymmetricAlgorithm and is the abstract representation of the Triple-DES algorithm, which is based on the DES. Individual implementations of Triple-DES will extend this class. The .NET Framework class library includes the TripleDESCryptoServiceProvider class, which is the default implementation.

In addition to the members defined by the parent class, TripleDES implements the IsWeakKey( ) method, which determines if the selected cryptographic key results in a cipher that is easy to break.
