DES算法为密码体制中的对称密码体制，又被成为美国数据加密标准，是1972年美国IBM公司研制的对称密码体制加密算法。其密钥长度为56位，明文按64位进行分组，将分组后的明文组和56位的密钥按位替代或交换的方法形成密文组的加密方法。
-DES algorithm in symmetric key cryptography system, also known as the United States Data Encryption Standard, was developed in 1972, the United States, IBM' s symmetric cipher encryption algorithm. The key length is 56 bits, 64 bits are grouped according plain text, plaintext after the packet and 56-bit bit key by the formation of alternative methods or exchange the encryption cipher group.
