A widely-used method of data encryption using a private (secret) key. There are 72,000,000,000,000,000 (72 quadrillion) or more possible encryption keys that can be used. For each given message, the k [..]

[A] cryptographic algorithm for the protection of unclassified computer data and published by the National Institute of Standards and Technology in Federal Information Processing Standard Publication 46-1. [INFOSEC-99] Note: DES is not approved for protection of national security classified information.

A data encryption standard developed by IBM under the auspices of the United States Government and adopted as a Federal Standard in 1977. DES uses a 56 bit key to perform a series of nonlinear transformation on a 64 bit data block. Even when it was first introduced a number of years ago, it was criticized for not having a long enough key. 56 bits j [..]

Data Encryption Standard (DES) is a widely-used block cipher encryption using a private (secret) key standardized by ANSI in 1981 as ANSI X.3.92. There are 72,000,000,000,000,000 (72 quadrillion) or more possible encryption keys that can be used. For each given message, the key is chosen at random from among this enormous number of keys. Like other [..]

A deprecated method of data encryption that uses a private (secret) key. For each given message, the key is chosen at random. Like other private key cryptographic methods, both the sender and the receiver must know and use the same private key. DES applies a 56-bit key to each 64-bit block of data.

(abbreviation: DES) A popular, standard encryption scheme.

A block cipher based on a symmetric-key algorithm that uses a 56-bit key. It is considered compromised and was replaced with 3DES (Triple DES), which applies the DES algorithm three times to each data [..]

An encryption algorithm standardized by the US Government. The key length is too short, so this algorithm should be considered insecure. The effective key strength is 56 bits; the actual key size is 6 [..]

The data encryption standard (DES) is a common standard for data encryption and a form of secret key cryptography (SKC), which uses only one key for encryption and decryption. Public key cryptography [..]

A method of encrypting information, traditionally used as the method of encryption for UNIX® passwords and the crypt(3) function.

DES. A cryptographic algorithm adopted by the National Bureau of Standards for data security. The algorithm encrypts or decrypts 64 bits of data using a 56-bit key. See also Triple DES.

A technique by which a message is scrambled into an indecipherable stream of bits for transmission.

DES is a popular single-key encryption system that uses a 56-bit key. Triple-DES uses the DES algorithm to encrypt a message three times, using three 56-bit keys. Because hardware is faster than software, it is considered a hardware solution to encryption because of the time necessary to encrypt and decrypt a message.
