[反汇编练习] 160个CrackMe之017.
本系列文章的目的是从一个没有任何经验的新手的角度(其实就是我自己)，一步步尝试将160个CrackMe全部破解，如果可以，通过任何方式写出一个类似于注册机的东西。
其中，文章中按照如下逻辑编排（解决如下问题）：
1、使用什么环境和工具
2、程序分析
3、思路分析和破解流程
4、注册机的探索
----------------------------------
提醒各位看客: 如果文章中的逻辑看不明白,那你一定是没有亲手操刀!OD中的跳转提示很强大,只要你跟踪了,不用怎么看代码就理解了!
----------------------------------
1、工具和环境：
WinXP SP3 + 52Pojie六周年纪念版OD + PEID + 汇编金手指。
160个CrackMe的打包文件。
下载地址： http://pan.baidu.com/s/1xUWOY 密码: jbnq
注：
1、Win7系统对于模块和程序开启了随机初始地址的功能，会给分析带来很大的负担，所以不建议使用Win7进行分析。
2、以上工具都是在52PoJie论坛下的原版程序，NOD32不报毒，个人承诺绝对不会进行任何和木马病毒相关内容。
2、程序分析：
想要破解一个程序，必须先了解这个程序。所以，在破解过程中，对最初程序的分析很重要，他可以帮助我们理解作者的目的和意图，特别是对于注册码的处理细节，从而方便我们反向跟踪和推导。
和上一节一样，打开CHM，选择第17个BJCM30A.exe，保存下来。运行程序，程序界面如下：
3、思路分析和破解流程
又见信息框，我很高兴啊！
PEID: Microsoft Visual Basic 5.0 / 6.0
和以前的一样，直接上步骤：
1、打开OD，将exe拖到OD窗口中，等程序暂停后，直接点击运行按钮(F9)，不用理会。
2、在exe中输入Key：bbdxf。点击OK按钮，弹出错误信息框，不要关闭。
3、在OD中点击暂停按钮(Ctrl+F2)，再点击堆栈K按钮(Ctrl+K)，可以看到当前堆栈情况。

随意向上翻翻，就发现了不同含义的文本，寻找je跳转，哈哈，是不是又被找出来了！
直接选中je 00404EE3 ，右键->Binary->Fill with NOPs.再试试：
哈哈，是不是被爆破了！
4、注册机的探索
写得多了，写到这里就郁闷了！
由于是VB程序，所以注册码比较的关键一般都是那几个文本比较函数，__vbastrcomp,__vbavartsteq,__vbastrcmp等。我们从关键跳转向上浏览，不理解的地方F8跟随：

对于上面的这一长段反汇编，我不想做什么详细解释了。前2/3部分都是For循环，并且没有做什么有用的东西，最后的msvbvm60.__vbaVarTstEq 附近才算了一些东西，但是我也没弄明白到底是怎么回事。所以，抱歉了！
由于使用OD没搞明白，使用VB Decoder反编译如下：
