DES (Data Encryption Standard) algorithm, in 1977 the U.S. government s official permission, is a 56-bit key to encrypt 64 data. 56 keys of the DES algorithm scenery is not, and often with Des encryption expressly decipher reported, but look at the old standard encryption algorithm is always useful, but the DES algorithm has been widely used in a some occasions, she still plays a waste heat. (such as: UNIX password algorithm is DES algorithm-based). To modify the Triple DES is also resistant to cracking.
