TripleDES
Synopsis
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(stringstr
); 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.
