MD5

使用MD5算法对数据和文件进行加密，信息安全(Using the MD5 algorithm to encrypt the data and documents, information security)

reversible Data Hiding in Encrypted Images by Reserving Room Before Encryption

说明：  matlab程序。基于二维混合混沌图像加密的算法。(Matlab program. Based on two-dimensional chaotic image encryption algorithm.)

RC5算法加密源码，例程程序调用RC5.dll资源库实现RC5算法加密。(RC5 encryption algorithm source code , a routine procedure calls RC5.dll repository achieve RC5 encryption algorithm .)

超级兔子有一个文件加密功能，文件被加密以后，打开该文件时，回转到控制面板，可是我们忘了密码怎么办呢？这里提供了一个简单方法-Super rabbit has a file encryption, file is encrypted then, open the file, back to the control panel, but we forget the password how to do? Here provides a simple way

MD5加密算法，实现报文认证！！运算速度快，兼容性好(MD5 encryption algorithm, message authentication realize! ! Computing speed, better compatibility)

这个程序是MD5算法的C源代码，调试通过。可以直接应用，在网络通讯中有用。(the procedure is MD5 algorithm in C source code, debugging through. Can be directly applied in the network communications useful.)
