摘要
对称密码算法又称单钥或私钥或传统密码体制，其发方和收方使用相同的密钥，即加密密钥和解密密钥是相同的。在众多的常规密码中影响最大的是DES密码。该文介绍DES算法的c语言实现。
Symmetric key cryptography, also called single key or private key or traditional cryptography, whose sender and receiver use the same key, in the other word, the encrypt key is just the decipher key. DES is the representative of the symmetric key cryptography. This paper describes DES algorithm using C language.
