The Data Encryption Standard (DES / ˌ d iː ˌ iː ˈ ɛ s, d ɛ z /) is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure for modern applications, it has been highly influential in the advancement of cryptography .
NetLib Encryptionizer supports AES 128/256 in CBC, ECB and CTR modes for file and folder encryption on the Windows platform. Pidgin (software), has a plugin that allows for AES Encryption; Javascrypt [8] Free open-source text encryption tool runs entirely in web browser, send encrypted text over insecure e-mail or fax machine.

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 Encryption Standard (DES) cipher's key space – that is, to decrypt an encrypted message by trying every possible key.
The Data Encryption Standard was a catalyst for further innovation in cryptography. Although now outdated, the idea behind DES was to create a government standard of encryption for unclassified or ...
It supersedes the Data Encryption Standard (DES), [9] which was published in 1977. The algorithm described by AES is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting the data. In the United States, AES was announced by the NIST as U.S. FIPS PUB 197 (FIPS 197) on November 26, 2001. [6]
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 this document. That is, bit number 1 is always the most significant bit.
Comparison of implementations of message authentication code (MAC) algorithms. A MAC is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed in transit (its integrity).
