标题：3Dmark2003注册号的算法研究
软件：3Dmark 2003
版本：3.1.3.0
下载网站：www.mydrivers.com
破解者: 火翼[CCG]
组织 : [CCG] (China Cracking Group)
使用软件: OllyDbg+Ida430

昨天才出来的软件，官方下载地址没提供注册号（官方当然不会提供）。
用IDA反汇编，搜索"Incorrect registration code."在41D8CA找到对这个字符串的调用，向上可以在0041D81E找到关键判断
.text:0041D81E call sub_405190 //关键判断
.text:0041D823 add esp, 4
.text:0041D826 test al, al
.text:0041D828 lea ecx, [ebp+var_6C]
.text:0041D82B jz loc_41D8CA
跟进去之后，代码如下
.text:00405190 push 0FFFFFFFFh
.text:00405192 push offset loc_596D31
.text:00405197 mov eax, large fs:0
.text:0040519D push eax
.text:0040519E mov large fs:0, esp
.text:004051A5 sub esp, 40h
.text:004051A8 mov eax, dword_611F00
.text:004051AD xor eax, [esp+4Ch]
.text:004051B1 push ebx
.text:004051B2 push ebp
.text:004051B3 push esi
.text:004051B4 push edi
.text:004051B5 mov edi, [esp+5Ch+arg_0]
.text:004051B9 mov ecx, edi
.text:004051BB mov [esp+5Ch+var_10], eax
.text:004051BF call ?size@?
$basic_string@DU?$char_traits@D@std@@V?
$allocator@D@2@@std@@QBEIXZ //MFC字符串类的方法
//得到字符串长度
.text:004051C5 cmp eax, 17h
//看输入的是否是23
//个字符
.text:004051C8 jnz loc_40540C
.text:004051CE push 5
.text:004051D0 mov ecx, edi
.text:004051D2 call ??A?$basic_string@DU?
$char_traits@D@std@@V?$allocator@D
@2@@std@@QBEABDI@Z //取字符串的第6
//个字符
.text:004051D8 cmp byte ptr [eax], 2Dh
//和"-"比较

以下还有两处，判断第12位和第18位是不是"-"
.text:00405207 push offset
a5azuhNzcd6La83 ; "5AZUH-NZCD6-LA83C-RW5KS"
//黑名单
.text:0040520C push edi
.text:0040520D call ds:??8std@@YA_NABV?
$basic_string@DU?$char_traits@D@std@@V?
$allocator@D@2@@0@PBD@Z //字符串比较
.text:00405213 add esp, 8
.text:00405216 test al, al
.text:00405218 jnz loc_40540C //相等就跳

现在开始时注册号的计算过程
一共分为3段
（1）把输入的字符串在字符表B2CD6FHJ1LN4RSTE3VWX8YZA0Q7MUK9P5
中的位置写道内存中
对应ZA5UH-NZCD6-LA83C-RW5KS
在内存中的数字就是
16 17 20 1C 06 -
0A 16 02 03 04 -
09 17 14 10 02 -
0C 12 20 1D 0D
每个数字占32位，“-“用ffffffff代表
代码如下
.text:0040521E lea ecx, [esp+30h]
.text:00405222 call ds:??0?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QAE@XZ ; std::basic_string<char,std::char_traits,std::allocator>::basic_string<char,std::char_traits,std::allocator>(void)
.text:00405228 lea esi, [esp+30h]
.text:0040522C mov dword ptr [esp+58h], 0
.text:00405234 call sub_404A20
.text:00405239 mov ecx, edi
.text:0040523B call ds:?size@?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QBEIXZ ; std::basic_string<char,std::char_traits,std::allocator>::size(void)
.text:00405241 push eax
.text:00405242 lea ecx, [esp+5Ch+var_38]
.text:00405246 call sub_405160
.text:0040524B mov ecx, edi
.text:0040524D mov byte ptr [esp+58h], 1
.text:00405252 xor ebx, ebx
.text:00405254 call ds:?size@?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QBEIXZ ; std::basic_string<char,std::char_traits,std::allocator>::size(void)
.text:0040525A test eax, eax
.text:0040525C mov esi, [esp+24h]
.text:00405260 jbe short loc_405298
.text:00405262
.text:00405262 loc_405262: ; CODE XREF: sub_405190+106j
.text:00405262 push ebx
.text:00405263 mov ecx, edi
.text:00405265 call ds:??A?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QBEABDI@Z ; std::basic_string<char,std::char_traits,std::allocator>::operator[](uint)
.text:0040526B movsx eax, byte ptr [eax]
.text:0040526E push 0
.text:00405270 push eax
.text:00405271 lea ecx, [esp+5Ch+var_24]
.text:00405275 call ds:?find@?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QBEIDI@Z ; std::basic_string<char,std::char_traits,std::allocator>::find(char,uint)
.text:0040527B mov ecx, ds:?npos@?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@2IB ; uint const std::basic_string<char,std::char_traits,std::allocator>::npos
.text:00405281 cmp eax, [ecx]
.text:00405283 jnz short loc_405288
.text:00405285 or eax, 0FFFFFFFFh
.text:00405288
.text:00405288 loc_405288: ; CODE XREF: sub_405190+F3j
.text:00405288 mov [esi+ebx*4], eax
.text:0040528B mov ecx, edi
.text:0040528D inc ebx
.text:0040528E call ds:?size@?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QBEIXZ ; std::basic_string<char,std::char_traits,std::allocator>::size(void)
.text:00405294 cmp ebx, eax
.text:00405296 jb short loc_405262
.text:00405298
.text:00405298 loc_405298: ;
（2）对内存中的编号进行运算得到正确的8个数
算法如下
前三个数是把前三段的头四个字符对应的编号相加再对21取余，
第4个数是把第5，11，17个字符的编号相加再对21取余，
第5个数是第11，17，19个字符的编号相加再对21取余，
第6个数是把第17，19，20个字符的编号相加再对21取余，
第7个数是把第19，20，21个字符的编号相加再对21取余，
第8个数是把第20，21，22个字符的编号相加再对21取余，

（3）把这八个数和输入注册号的对应位编号比较
第一个 5位
第二个 11位
第三位 17位
第四个 19位
第五个 20位
第六个 21位
第七个 22位
第八个 23位
代码如下

.text:0040539D jnz short loc_4053F1
.text:0040539F cmp [esi+28h], ebx//2

.text:004053D0 jnz short loc_4053F1
.text:004053D2 lea ecx, [esp+20h]
总结
注册号生成算法如下
先在字符串B2CD6FHJ1LN4RSTE3VWX8YZA0Q7MUK9P5中任取12位
组成XXXXa-XXXXb-XXXXc-defgh形的字串，X为任取的字符，
a,b,c位对应的前面4个字符在字符串B2CD6FHJ1LN4RSTE3VWX8YZA0Q7MUK9P5中的位置编号（16进制）相加再对21（16进制）取余得到数字对应位置的字符，d为a，b，c位置编号相加再对21取余得到数字对应位置的字符,e为b，c,d位置编号相加再对21取余得到数字对应位置的字符,f为c,d,e位置编号相加再对21取余得到数字对应位置的字符,g为d,e,f位置编号相加再对21取余得到数字对应位置的字符,h为e，f，g位置编号相加再对21取余得到数字对应位置的字符。
