SM4算法PC源码.docx

1、SM4算法PC源码 SM4算法实现说明：1、 纯源码无库实现，编译环境：VC+ 6，建立工程把程序文件加入编译即可2、 源码文件包括：main.cpp，SM4.cpp头文件： SM4.h该算法通过商用测试，下载后如果有使用问题联系QQ： 1900109344源码 SM4算法例程(main.cpp，SM4.cpp， SM4.h)SM4.h#define KeyLenError 0x01#define PlainLenError 0x02int Tt(const int preS);int TL(int B);int TotherL(int B);int T(int input);int Toth
