【软件简介】：ChinaRen校友录伴侣（以下简称CRAP）是一款专门针对ChinaRen校友录设计的共享软件。您或许曾因为ChinaRen的速度太慢而无法浏览自己班级的最新留言；您或许想看看班级以往的留言，但由于一页一页的翻阅太麻烦而苦苦等待；您或许想查找以往的某一条留言，但由于留言太多而无从下手；您或许为由于ChinaRen服务器瘫痪所造成的班级留言的丢失而遗憾；您或许……你还是试试吧。
【软件限制】：功能限制。每一个用户名进行一次注册。
【作者声明】：初学Crack，只是感兴趣，没有其它目的。失误之处敬请诸位大侠赐教！
【破解工具】：TRW2000娃娃修改版、Ollydbg1.09、FI2.5、W32Dasm8.93黄金版
—————————————————————————————————
【过 程】：
Crap.exe无壳。DELPHI编写。反汇编，查找出错提示，很容易找到核心。
伪装者[CCG]大侠曾写过v1.01 build 10717 的注册机，2.01版的算法还是差不多一样的。
有些分支判断就没写了，如果自己追一下就知道了。
