目标程序: Internet Download Manager 6.25

工 具：吾爱OD MASM32
平 台：Windows7 32-bit
在没开始之前，我得先声明，我在这里只解析一下这个软件的注册算法以及一个简易的算号器，至于Hosts屏蔽之类或者直接修改软件，大家自己动手吧，我在这里只说一下实现本地注册的流程。网上有很多这样的配置文章，或者论坛上面有很多修改版本，都很好用，我在这里只是学习一下该软件的算法，在这里我上两篇这方面的文章：

好了，我们开始吧！这个软件真正分析起来，其实应该先构造一个假码，在试过错知道，序列号应该满足以下几个基本要求：
1、长度为23位
2、序列号每个子串要用连字符'-'隔开
3、如SN1-SN2-SN3-SN4形式，每个子串都五位长度

接下来就是简单的判断一下姓、名以及邮箱、序列号是否为空，完成这些基本条件后，再将整个假码大写：
[Asm] 纯文本查看 复制代码 00502563 |. 52 push edx
00502564 |. E8 42E10C00 call IDMan.005D06AB ; //将序列号大写
00502569 |. 8DBD 7CFFFFFF lea edi,dword ptr ss:[ebp-0x84] ; ASCII "12345-789AB-DEFGH-78900"
0050256F |. 83C9 FF or ecx,-0x1
00502572 |. 33C0 xor eax,eax ; ntdll.77C4D63E
00502574 |. 83C4 04 add esp,0x4
再进一步确定序列号的长度为23，是否被连字符分割，然后初始化一个非常重要的标志位。
[Asm] 纯文本查看 复制代码 0050257B |. 49 dec ecx ; ASCII "12345-789AB-DEFGH-78900"长度
0050257C |. 83F9 17 cmp ecx,0x17 ; //真正序列号的长度要23位
0050257F |.^ 75 98 jnz short IDMan.00502519 ; //跳则出错
00502581 |. 8A4D 81 mov cl,byte ptr ss:[ebp-0x7F] ; //取序列号第六位
00502584 |. 8845 EF mov byte ptr ss:[ebp-0x11],al ; //给标志位赋值，此时AL为0
00502587 |. B0 2D mov al,0x2D
00502589 |. 3AC8 cmp cl,al ; //比较序列号第六位是否为连字符
0050258B |. 75 0A jnz short IDMan.00502597 ; //序列号第六位不为连字符则跳
通过下面的好几处地方可以看到byte ptr ss:[ebp-0x11]这个标志位只要被置一，整个注册任务就会失败，所以我们要想方法跳过。接下来就是通过连字符，将序列号分割成四个子串：

005025DA |. 33FF xor edi,edi
005025DC |. 83C4 30 add esp,0x30
每个子串末尾添加字符串结束符：
[Asm] 纯文本查看 复制代码 005025DF |. C645 D9 00 mov byte ptr ss:[ebp-0x27],0x0
005025E3 |. C645 D1 00 mov byte ptr ss:[ebp-0x2F],0x0

005025EF |. 897D E8 mov dword ptr ss:[ebp-0x18],edi
再下面就是一个比较大的循环，在全局数组里面逐个寻找假码所在的位置，然后得出假码在全局数组的下标，这个下标将参与下面的运算。简单描述一下，一个关于索引的表达式：
[Asm] 纯文本查看 复制代码 EDI=EAX+EDI+(EDI+EDI*8)*4 (EDI初始为0)
= EAX+37*EDI
下面三个循环将分别计算SN2,SN3,SN4，代码虽然有点不同，但是本质上还是我上面给出我那个公式，大家在最后看我的注册机源码就会知道了，简单粘贴一下：

上面这串代码实际上就是要每个子串循环得到的一个数值要被不同的整数整除，所以在做注册机的时候，我们只要写好一个函数，别外三个就小小改动一下就好了，关于上面这段代码，我粘贴一下我的推导过程，比较简单。

比较乱，但是应该很容易明白。好了，我贴一下我的源码和简易的注册机，关于序列号的构造，源码里面写得很清楚，比较简单。但是屏蔽网络就自己去参考一下别的吧，比较简单，主要是弄清楚算法，这样以后自己也知道怎么打补丁，不是吗？附带我的UDD：
