  实例：PDFill PDF Editor
  官网：www.pdfill.com

   平台：Windows7 sp1(32位),Windows XP(雨林木风)
目标：对CNET上一款名为"pdfill"的免费试用型软件的注册算法进行逆向    工具：吾爱OD

大家可以进入官网点击download边栏找到下载链接，我在这里也上传一份: http://pan.baidu.com/s/1gdAX8T9 密码: 2b8b

  来到吾爱也有大半年了，当时用的也是开放注册的方式融入这个集体的，这半年来一直在学习并收获也不错。别人我不知道，每个人都有自己的兴趣爱好和目标定位，对于我来说，我就是想细致的剖析出某某软件的具体算法，而非热衷修改某某软件、暴力破解之类。所有的方式都可以用来提高自己，大家一起加油！

  首先列出一下我分析算法的流程：
  (1) 下好断后，来到关键跳，分析关键CALL的返回值对关键跳转的影响
  (2) 从下断处单步(F8)走，记录好每一步在堆栈、寄存器中出现的可疑字符串
  (3)  重点分析关键CALL并完善算法

  好了，我们先下载好并打开软件，界面如下

  选择菜单 Help -> Enter Registration Code  输入相应的名字、邮箱和假码，可以自己用自己的，我用的下面:

  First Name: Ashe
  Last  Name: Green
  Email Addr: aikuimail@52pojie.cn  (捏造的一个邮箱:)
  Serial Num: 123456789

提示注册码必须是12位，所以将假码改成123456789123
查壳，VC写的：

好了，开始我们的第一步，首先用OD打开软件并运行，输入我们准备好的信息后，点击OK后弹出错误窗口

不要忙着点OK，来到OD点暂停按钮，查看调用堆栈，然后在段首下好断点，这里我就不详细说明了，毕竟看这帖子的不可能是纯新手，说多了可能有灌水的嫌疑，这里用到的是暂停法。下面我就贴代码了,第一次发帖，有错位的地方请见谅啊！

到这里大家就已经知道如何暴力破解了，方法很多，这里我就不多说了，我们要分析算法，就要跟进关键CALL。由于我也是一个重度强迫症患者(或许是...:)，所以在这里不管大家愿意不愿意，我都要把上面的代码重新贴出来然后进行详细的解释，至少未来某天我在长期的懒惰后幡然醒悟过来想要复习的时候，还能找到自己的学习笔记。好吧，我也不知道上面的代码编排是不是已经稀烂了，我将上面的代码重新贴一次。

从上面关键算法进入到这里:

其实真正说起来，前面写的东西全部是废话(但请不要把它等价于灌水，我会有惩罚的)，到了这段代码才是真正的算号函数。前面全部都是些验证机制，由于发帖很耗时间，我也有很多的语句都没有写明白，只在心中有个数，即使我有心有力，这帖子排版也不允许我这样做，本来就不会排，再来几下这帖子就不用看了。所以，请见谅啦！好了，我会精解这一段。

如果都用上面的方式来讲解的话，动手能力稍差的朋友就云里雾里了，所以，下面我们换一种方式。因为这段运算代码是一个大循环，所以我就先用Ashe这个First Name来做实验，实时截图从EDI这个累加器开始:

此时EDI被清零,我们单步往下又看到一个计数器，生手请记住这两个计数器，等你熟练后就自然知道怎么判断是计数器了。

然后到下面，将Ashe里面的大写变小写，好奇的可以跟进去看见wcslwr_s这个函数:

[Asm] 纯文本查看 复制代码

lea ecx,dword ptr ss:[ebp+0xC]                           :将Ashe地址放入ECX
call dword ptr ds:[<&mfc100u.#7871>]             ;将所有大写字母转换成小写  wcslwr_s

再到下面就是整个算号程序百分之九十几的算法精华了：

  这一小段汇编代码我不知道怎么编排，不明白的朋友也不用报怨，因为如果你是自己边看边动手的话，一切就变得简单化了！如何实在不明白的朋友可以留言。

  整个First Name的算号流程是：
计数器->ss:[ebp-0x14]
“Ashe"->"ashe"
得到第一个字母a的ascii码为0x61

然后利用公式:
1、名字的ASCII码+8+计数器 => ECX
      所以ECX=0x61+0x8+0x0 = 0x69
   2、计数器+9 => EDX
      所以EDX=0x0+0x9=0x9
3、ECX*EDX +EDI=> EDI
      所以EDI=0x69 * 0x9 = 0x3B1

  算完了a我们再手动算下s,然后再验证结果。
此时[ebp-0x14]是1
   ECX=0x73+0x8+0x1=0x7C
   EDX=0x1+0x9=0xA
   EDI=0x889
   然后再算h和e,把每次EDI的结果累加起来,最后我得到的结果是0x12AF，然后再在OD用F4看看结果，是正确的。
   再把First Name最终的换算结果也就是EDI的值加上一个固定的数字0x10E1,0x12AF+0x10E1=0x2390
   然后亲们，再用计算器把0x2390转换成十进制等于9104这就是由First Name换算得到的序列号了。
   因为9104没有超过4位，所以不截取。
   用同样的方法算出Last Name生成的序列号为：15484(十进制),这个时候长度超过了4，所以要从后向前截取四位为5484
   同样，邮箱的生成57375，截取为7375,关于这个截取函数用的是宽字符的截取函数，大家可以看看，整个程序用的UNICODE编码，而不是DBCS

   所以最后的序列号为：910454847375
   用邮箱生成的时候也是一样的方法，包括@以及“."之类的特殊符号都要翻译成相应的ASCII码再计算！！！
这只是一个简单的程序，相信大家也能猜到，一共只能12位的序列号要用一个Last Name,一个First Name和一个Email来生成，序列号的形式可想而知。
   算法都这么清楚了，相信写注册机也不在话下了吧。第一次发贴，肯定有很多不足的地方，还请大家多多包涵，写注册机我推荐用H大大分享的汇编注册机模板，大家可以搜一搜。
