Therefore, data encryption has become a big problem we are facing. The purpose is to make the information through the Internet transmission, even if the theft or intercepted, also let your opponent cannot understand the true meaning of, for illegal users, which is equivalent to a garbled. Firstly, .Through the study found that the DES algorithm is today widely encryption algorithm, is also the most representative block encryption algorithm, although the DES encryption algorithm in front of some technology has being cracked, but with its own advantages, related products m...
