The Data Encryption Standard (DES / ˌdiːˌiːˈɛs, dɛz /) is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure for …

DES supplementary material This article details the various tables referenced in the Data Encryption Standard (DES) block cipher. All bits and bytes are arranged in big endian order in …

The setup for each round is generally the same, except for round-specific fixed values called a round constant, and round-specific data derived from the cipher key called a round key. A key …

In cryptography, the EFF DES cracker (nicknamed " Deep Crack ") is a machine built by the Electronic Frontier Foundation (EFF) in 1998, to perform a brute force search of the Data …

In cryptography, Triple DES (3DES or TDES), officially the Triple Data Encryption Algorithm (TDEA or Triple DEA), is a symmetric-key block cipher, which applies the DES cipher …

A discrete-event simulation (DES) models the operation of a system as a (discrete) sequence of events in time. Each event occurs at a particular instant in time and marks a change of state in …

The GNU C Library (glibc) used by almost all Linux distributions provides an implementation of the crypt function which supports the DES, MD5, and (since version 2.7) SHA-2 based hashing …

Like other components of the DES, the iterative nature of the Feistel construction makes implementing the cryptosystem in hardware easier (particularly on the hardware available at …
