MD5加盐处理

对RC4加密解密代码，可以自行修改密钥!类可以直接调用(RC4 encryption and decryption code, you can modify the key! Class can be called directly)

Some example methods to evaluate and break simple RSA

这个是MD5算法C的源代码，希望对大家有用-This is the MD5 algorithm C source code, in the hope that useful to everybody

SHA-1 algorithm implemented in C.

VC做成的MD5的算法工具，可以学习一下-VC made the MD5 algorithm tool to study the

说明：  16轮DES加解密和3轮差分攻击 含有测试样例 基于python(16 Rounds of DES Encryption and Decryption and Differential Attacks)

DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。DES算法以被应用于许多需要安全加密的场合。（如：UNIX的密码算法就是以DES算法为基础的）。-DES (Data Encryption Standard) algorithm, in 1977 the United States government"s official permission, is a key 56 to 64-bit data encryption methods. DES algorithm to be applied to many needs security encryption occasions. (Eg : UNIX password algorithm is to DES algorithm-based).
