线性移位寄存器是流密码的重要组成部分，该程序就是实现该方法。- The linearity shift register is the stream cipher important constituent, this procedure realizes this method.

利用C语言实现的cmac算法，该cmac基于AES。程序清晰有注释便于查看(The use of C language cmac algorithm, the cmac based AES. There are clear and easy to view program notes)

c++实现密钥为4的凯撒密码加密，其中支持明文的大小写-c++ achieve key for Caesar 4 password encryption, which supports the explicit case

JAVA加密算法之一，不过支持256位加密-JAVA encryption algorithm, however, support 256-bit encryption

IDEA(1/8) 功能模型,用matlab语言实现-IDEA (1/8) functional model, using matlab language implementation

对初学MALAB读的经典外文书籍，简单易懂，有简单代码-Novice MALAB reading the classic books in foreign language, easy to understand, there is a simple code

DES密码体制的安全性应该不依赖于算法的保密，其安全性仅以加密密钥的保密为基础-DES password security system should not depend on secrecy algorithm, the only security encryption key based on the confidentiality

这个是编译通过的MD5算法，使用的语言是C++，非常好用。(MD5 C++ source code )
