【破解过程】

用PEID查看是PECompact 2.x -> Jeremy Collake的壳，设置Ollydbg忽略所有的异常选项

00401000 > B8 58CB4100 MOV EAX,Tbcpro.0041CB58 ; 停在这里

00401005 50 PUSH EAX

00401006 64:FF35 00000000 PUSH DWORD PTR FS:[0]

00401016 8908 MOV DWORD PTR DS:[EAX],ECX

00401018 50 PUSH EAX

00401019 45 INC EBP

0040101A 43 INC EBX

下断：BP VirtualFree （这些API经常要，要记住），运行后，取消断点，ALT+F9

返回，再走几不就到OEP了

下断短在这里：

7C809B29 5D POP EBP

ALT+F9到这里：

0041CC19 5B POP EBX

0041CC1A 5D POP EBP

0041CC1B FFE0 JMP EAX ; JMP OEP

OD插件可以脱壳了，我这里不要修复就可以运行了，脱壳完成。

看算法了，输入Order ID and Regcode后，看到有错误提示，不会加密字符吧，老

罗插件看看，没有加密，找到字符后下断这里：

Order ID的要求总结一下，就是要前十位数字是0-9，第十一位是“-”，第一个“-”

后面还必须有0-9的数字，后面还要有一个“-”，“-”后数字随便，就OK

举例：1234567890-1123-0000

表达能力较差，不要骂我啊

到这里算法就完毕了，比较简单。

【破解心得】

这个软件刚开始的串传送时候的字符可能各个机子上不一样，就是那段字符解密比较重要

啊，写文章真的好累，破花了一点时间，可写花了不少时间啊

----------------------------------------------------------------------------------------------

【破解声明】我是一只小菜鸟，偶得一点心得，愿与大家分享
