修正了原CMd5类的CaculateStr函数的严重错误，并且转到新的C++类库。此类已经经过验证，文件和字符串均能得到正确结果，支持Unicode（Unicode时不需要转换）-amendment of the original CMd5 CaculateStr function of the type of serious errors and to the new C Class. Such has been validated, documents, and the string to get the correct result, Unicode support (Unicode does not need conversion)

本程序提供密钥产生的一些基本数学实现 用c++实现-This procedure provides the key generated by using some basic math c++ Realize

程序运行时间限制的封装类-running time limits the types of Packaging

java实现的Caesar移位密码，可以实现加密和解密功能！(java implementation of the Caesar shift passwords, encryption and decryption functions can be achieved!)

SPN代换-置换算法的c实现，以及使用差分分析进行破解。(SPN substitution- replacement algorithm c implementation, and use of differential analysis to crack.)

RSA数据加密代码，用C编写，已压缩成RAR格式-RSA data encryption code, prepared by C, has been compressed into RAR format

利用VC来实现一个简单的DES加密程序，他能完成DES算法的全部步骤，不过只能使用64位密码对64位明文进行加密-VC to achieve a simple DES encryption program, he can finish all the DES algorithm steps, but only use 64 to 64 passwords expressly encryption

我根据comp430s改写的DLL源码，可在多线程下使用。还带有DES加密算法函数 -DLL source which is overwirted by comp430s, can be used in multi-thread.Attached by DES encryption Algorithm

一个完全使用java编写的加密通用算法包，含des,des3,rsa等很多加密算法源码- Completely uses the java compilation the encryption general algorithm package, contains des, des3, rsa and so on very many encryptions calculates the law origin code
