它的演算法已經明確，就做個序號產生器吧。
TC 2.0下除錯透過
#include "stdio.h"
int key[48]={'B','i','X','w','D','I','d','i','5','1','6','8','q','c','I','E','F','M','E','W','D','S','V','d','k','v','m','e','m','i','f','P','C','i','E','s','e','f','G','F','2','1','Q','C','L','M','W','E'};
main()
{
  char S[10],*p=S;
  int *p1=key;
  unsigned long a,b,c,d,e;
  printf("ChengYuSuCha v3.0 keygen by HMILY[BCG]\n");
  printf("My e-mail : gyyxll@21cn.com\n");
  printf("***************HMILY[BCG]***************\n");
  printf("please enter your serial : ");
  gets(S);
  printf(" Your register code is : ");
  while(*p!='\0')
    {
    a=*p&0x0F;
    b=*p1&0x0F;
    c=a^b;

    printf("%c",e);
    }
