献给象我一样想学算法的同志们
1、字符串查找“invalid serial number or name.\n\nyou may need to remove one or more periods from the name”,可以找到如下代码
:
004DAFE8 /. 55 push ebp
004DAFE9 |. 8BEC mov ebp, esp
004DAFEB |. 33C9 xor ecx, ecx

2、跟进 004DB069 call 004DA0C8 得到:

【算法总结】
------------------------------------------------------------------------
1、首先是一个固定字符“CB”,这个值也许每个人装了软件后不同,但我的无论怎么弄都是这个字符。
2、根据这个固定字符得到“7CD”(第一次)或者“1F37”(第二次)。
3、用户名变大写后,逐个取用户名的ASCII值(16进制),乘以固定值7CD(1F37),再-1。然后累加在ESI中。
4、将刚才ESI中的值转成10进制,在和“RKS-”固定字符串连接就是注册码了。
5、注册码有两个的,随便一个都可以注册成功。注册信息保存在根目录的“CB.ini”里面
用户名:binbinbin
注册码:RKS-1300038(或者RKS-5202132)
