MD5加密算法源代码+DLL成品,这个更好,有完整的VC源码,更加强大,可以直接做成DLL文件进行调用.特爽,MD5就不用说了吧.-MD5 encryption algorithm source code DLL finished, the better, a complete source VC, more powerful, and can directly cause for calling DLL files. Special autumn, MD5 would not have said it.

md5 算法的纯c版本。方便移植到各种嵌入式小型设备不支持c++的环境-md5 algorithm with pure C version. Easy to transplant it to systems using only C, but not C++

RC2算法源代码-RC2 algorithm source code

超级增强断点源代码!配合trw2000和sice 使用!可以调试一些反调试的外壳和程序! 用vc编译-Super enhance breakpoint source code! Sice tie trw2000 and use! Some anti-debugging can debug shell and procedures! Compiling with vc

its about new technque using stream cipher
