Data Encryption Standard (DES) Implementation

The Data Encryption Standard (DES) shall consist of the following Data Encryption Algorithm (DES) and Triple Data Encryption Algorithm (TDEA, as described in ANSI X9.52). These devices shall be designed in such a way that they may be used in a computer system or network to provide cryptographic protection to binary coded data. The method of implementation will depend on the application and environment. The devices shall be implemented in such a way that they may be tested and validated as accurately performing the transformations specified in the following algorithms.
