这个例子描述了MD4碰撞，很有研究价值，大家可以仔细研究下...

用Visual Studio 2003编的文件加密程序，能对文件进行二进制读入，再和密码做异或，保存。版本一-Visual Studio 2003 for use of file encryption program, can read a binary file, and then do XOR and password, save. Version 1.0

Delphi加密控件源码，包括对称钥匙加密控件和散列函数控件 -Delphi encryption controls the source code, controls including the symmetrical key encryption and disperses the row letter numerical control

Here is static lib based on PPMD var E by Dmitri Shkarin, compiled with Visual Studio 6

其实网上这方面的代码已经不少了,但是大多都如出一辙,主要是给出的代码不但不好理解(主要是为了处理大文件,支持分块,这样就会屑弱初学者对算法的理解),该源代码在引入必要头文件后可以在VC6.0下顺利通过编译-fact that the Internet has been a lot of code, but most of all the same, given the code is not only poor understanding (mainly to handle large files, support block, which would litter beginners weak understanding of the algorithm), the source code necessary to the introduction of the first document in VC6 .0 smoothly through the compiler

字节取反-Take anti-byte

算法参考于《密码编码学及网络安全》上关于RSA加密算法的定义。相关程序在Visual C++ 6.0上能正确运行（估计在其他C语言编程环境下也能运行吧），程序里面详细写上了注解，希望能够给你带来帮助。
