The ICryptoTransform interface defines the basic operations of a symmetric block cipher, and is used in conjunction with the CryptoStream class to transform data. Implementations of this interface are most commonly obtained through the SymmetricAlgorithm.CreateEncryptor( ) and SymmetricAlgorithm.CreateDecryptor( ) methods.
