DS28E01 加密算法 C代码，经过测试没有问题。(DS28E01 C code)

实现RC4流密码算法，对文件进行加密，并将加密的内容以文件形式输出，控制台调用。(Achieve RC4 stream cipher algorithm, to encrypt files and encrypt the contents of the output file format, called the console.)

检测CRC编码 看CRC编码在传输后是否有错误 有变动 (Detection CRC codes to see whether the CRC coding errors in the transmission there is a change)

说明：  cox方法展频水印matlab源码，对bitmap图像隐藏信息(frequency watermarking method Show Matlab source of bitmap images for hidden messages)

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

rsa算法实现，用的是c++。欢迎大家随便下载-rsa algorithm, using c++. Welcome to the casual download

双随相位加密系统的加密程序，调试好的，没有错误-4f

可以实现文件加密功能的小软件源码，是学习文件操作和指针应用的好例程。(Can achieve a small file encryption software source code, is to learn the application file operations and pointers good routines.)

应用密码学的应用，实现密码算法，用C语言实现。(application of cryptography applications, password algorithm, using C language.)

这是一个好用的MD5的C++类；这个类可以加在控制台 程序中也可用在MFC中， 并且提供了详细的错误处理 函数，是一个安全的类。例程是一个MD5的MFC程序， 支持字符串和文件两种输入。-This is an easy to use the MD5 of the C++ Category this category can be added to the console program can also be used in MFC, and it provides a detailed error handling function, is a safe type. MD5 is a routine procedure of MFC to support the two input strings and documents.
