This class extends SymmetricAlgorithm and is the
abstract representation of the Digital Encryption Standard (DES)
algorithm. Individual implementations of DES extend this class. The
.NET Framework class library includes the
DESCryptoServiceProvider class, which is the
default implementation.
In addition to the members defined by the parent class,
DES implements the IsSemiWeakKey(
) and IsWeakKey( ) methods, which
determine if the selected cryptographic key results in a cipher that
is easy to break.
