RSA C++源代码DEMO,附加DESMD5等众多算法

function defination:

   void  (*SHA1) ( unsigned char *pt, unsigned long pt_len, unsigned char *digest );
   void  (*rsa_encrypt( char *pN_ASCII, char *pE_ASCII, char *pData_ASCII, char *pOUT_ASCII );


samples:

    HMODULE    hDLL;

    char   text[]="\x11\x11\x11\x11\x11\x11\x11\x11\x11\x11";
    char   result[32];

    if ((hDLL = LoadLibrary("crypto32.dll")) == NULL ) return ;

    (void *)SHA1      = (void *)GetProcAddress(hDLL,"_SHA1");

    memset(result,0x0,sizeof(result));
    SHA1(text,10,result);

    if (hDLL)
       FreeLibrary(hDLL);
