前不久鄙人很好用的C-Free3.5突然要求需要注册码进行注册，于是就去网上有无注册机乎，经历九九八十一难，终找到一能用的破解程序，运行后输入机器码，问题得到解决，鄙人欣喜不已，欣喜之余，鄙人将此程序发上来与大家共享，希望对大家有用。程序如下：

#include "stdlib.h"
#include "stdio.h"
int main(int argc, char* argv[])
{
char chKey[128] = {0};
unsigned int unXORCode, unRemainder, unQuotient, unTmp, unMachineCode;
printf("Please Key in the Machine Code:\n");
scanf("%d", &unMachineCode);

unXORCode = unMachineCode ^ 0x90909090;
unRemainder = unXORCode % 0x25;
unQuotient = unXORCode;
if (unRemainder < 0x11)
{
unRemainder += 0x11;
}

int i;
i = 0;
while (unQuotient != 0)
{
unTmp = unQuotient % unRemainder;
unQuotient /= unRemainder;
if (unTmp >= 0xa)
{
unTmp = unTmp + 0x61 + 0xf6;
unTmp &= 0x0ff;
chKey[i] = unTmp;
}
else
{
chKey[i] = unTmp + 0x30;
}
i++;
}
printf("Key is: \n");
while (i >= 0)
{
printf("%c", chKey[i]);
i--;
}
printf("\n");

return 0;
}
