<p align="left"><span class="p9"><font face="宋体">我在《Windows优化大师》这个软件开始使用某种加密算法时就在破解时有点摸不着头脑，不知道这个算法是RSA加密算法。自从几个月前拜读了《论坛精华Ⅱ》中的《Windows优化大师v2.9+的注册码加密算法》一文后我就开始按照该文所讲的方法编写注册机，从此噩梦开始......</font></span></p>
<p align="left"><span class="p9"><font face="宋体">我先把n=0x0000000069AAA0E3进行因子分解求出p=0x80BD和q=0xD21F，于是就求得f=0x0000000069A53372，然后又按照第四条规则很辛苦地编程求出d=0x000000003E0877FD。至此我想应该可以顺利地编写出注册机了吧，然而作出来的注册机不但算出来的注册码不对，而且用加密算法算出来的结果不能用解密算法还原成原来输入的两个数值。这个问题一直弄得我头大，直到最近我从别人那弄的一个注册申请码和正确的注册码，我才算出解密密钥d不是0x000000003E0877FD，而是0x00000000002C86F9，于是我终于写成了注册机。</font></span></p>
