Encryption, Standard Encryption

(DATA ENCRYPTION STANDARD) Data Encryption Standard (DES) is an encryption algorithm , ie a method for encrypting information, FIPS chosen as in the United States in 1976, and whose use is widespread throughout the world. The algorithm was initially controversial with classified design elements, a relatively short key length, and the continuing suspicions about the existence of a backdoor for the National Security Agency (NSA). DES was subsequently subjected to intense academic analysis led to the modern concept of block ciphers and their cryptanalysis. Today, DES is considered unsafe for many applications. This is mainly due to the size of 56-bit key is short DES keys are broken in less than 24 hours. Analytical results also exist that show theoretical weaknesses in encryption , but are unfeasible in practice. It is believed that the algorithm is safe in practice variant of Triple DES, although there are theoretical attacks. In recent years, the algorithm has been replace...
