The Data Encryption Standard (DES) shall consist of the following Data Encryption Algorithm to be implemented in special purpose electronic devices. 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.

Once the key scheduling and plaintext preparation have been completed, the actual encryption or decryption is performed by the main DES algorithm. The 64-bit block of input data is first split into two halves, L and R. L is the left-most 32 bits, and R is the right-most 32 bits.

This is a pure python implementation of the DES encryption algorithm. It is in pure python to avoid portability issues, since most DES implementations are programmed in C (for performance reasons).

This publication specifies the Triple Data Encryption Algorithm (TDEA), including its primary component cryptographic engine, ... With the withdrawal of the FIPS 46-3 standard: 1. Triple DES (i.e., TDEA), as specified in ANSI X9.52, Keying Options 1 and 2, is recognized as the only FIPS approved DES algorithm. 2.

DES encrypts and decrypts data in 64-bit bloc ... Since it always operates on blocks of equal size and it uses both permutations and substitutions in the algorithm, DES is both a block cipher and a product cipher. DES has 16 rounds, meaning the main algorithm is repeated 16 times to produce the ciphertext.

A variant called Triple-DES (TDES or 3DES) uses a longer key and is more secure, but has never become popular. The Advanced Encryption Standard (AES) is expected to supersede DES (and 3DES) as the standard encryption algorithm. ... The various permutations and transformations in the DES encryption algorithm...
