Diamond加密算法-A Diamond encrypt arithmetic

playfair的源代码，很简洁，跟网上现存的版本有所差异，但是效果是很不错的。-playfair source code is very simple, with the existing version of the web is different, but the effect is very good.

简单的基于DES的加密算法及雪崩效应分析。请仔细阅读内附的说明文件。(DES encryption algorithm and analysis of avalanche effect. Please read the attached note.)

设计一套完整实用的RSA文件加密解决方案，具体编码实现。对RSA算法进行研究，从常规RSA算法出发，用C++实现RSA加密算法类库，并在32位windows ... 使用VC编写的文件操作类FileTool,主要有四个函数: //加密文件,输入参数为文件名,采用了BlowFish加密算法-Design a complete set of practical RSA file encryption solution to achieve a specific encoding. Research on the RSA algorithm, starting from the conventional RSA algorithm, using C++ Realize RSA encryption algorithm class library, and 32 in the windows ... the use of VC types of documents prepared for the operation FileTool, has four main functions:// encryption files, input parameters for the file name using the BlowFish encryption algorithm
