DES The U.S. Data Encryption Standard (= DES) is the most widely used encryption algorithm, especially used for protection of financial transactions. It was developed by IBM in 1971. It is a symmetric-key cryptosystem. The DES algorithm uses a 56-bit encryption key, meaning that there are 72,057,594,037,927,936 possible keys. for more information see: http://www.britannica.com/bcom/eb/article/3/0,5716,117763+5,00.html http://www.cryptography.com/des/ http://www.britannica.com/bcom/eb/article/3/0... http://www.cryptography.com/des/
