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, 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 …

DES-X In cryptography, DES-X (or DESX) is a variant on the DES (Data Encryption Standard) symmetric-key block cipher intended to increase the complexity of a brute-force attack. The …

The Advanced Encryption Standard (AES), the symmetric block cipher ratified as a standard by National Institute of Standards and Technology of the United States (NIST), was chosen using …

Six common block cipher modes of operation for encrypting In cryptography, a block cipher mode of operation is an algorithm that uses a block cipher to provide information security such as …

An analysis of the algorithm's internals is undertaken; the standard method is to trace a path of highly probable differences through the various stages of encryption, termed a differential …
