Mini VC6.0
Mini VC6.0 首先新建头文件des_encode.H
内容如下：
void EncodeMain(); //EncodeMain function
void DecodeMain(); //Sorry ,it has not used
void Decode(int *str,int *keychar); //decode :input 8 chars,8 keychars
void Encode(int *str,int *keychar); //encode: input 8 chars,8 keychars
void keyBuild(int *keychar); //create key array
void StrtoBin(int *midkey,int *keychar); //change into binary
void keyCreate(int *midkey2,int movebit,int i); //call by keyBuild
void EncodeData(int *lData,int *rData,int *srt); //encodedata function
void F(int *rData,int *key); //F function
void Expand(int *rData,int *rDataP); //Expand function
void ExchangeS(int *rDataP,int *rData); //S-diagram change
void ExchangeP(int *rData); //P change
void FillBin(int *rData,int n,int s); // data to binary;call by S-Diagram change function
void DecodeData(int *str,int *lData,int *rData); //DecodeData from binary
int IP1[]={58, 50, 42, 34, 26, 18, 10, 2, 60, 52, 44, 36, 28, 20, 12, 4, //initial change

再创建des.cpp
内容如下：
