Beyond Compare 1.9f注册算法&注册机 (8千字)
-
目标:Beyond Compare 1.9f
下载:www.scootersoftware.com
简介:功能强大的文件比较工具,正是我要找的
原因:论坛上有人介绍,下载后发现要注册
程序出了2.0 beta版,看了一下,难度较大,blowfish大哥说1.9版比较好用,先用着先吧.此次破解比较简单,程序初运行出现提示框,选输入注册码按键,填入注册信息,下bpx hmemcpy,查找后用bpm,调试过程中发现程序用了WritePrivateProfileStringA的函数,原来程序先将注册信息写入INI文件,再读出做运算,错误的话要求你重新输入.
在windows目录下发现beyond32.ini文件,打开后找到以下注册信息:
[Registration]
Version=1.9f
InstallCode=000091FD
Evaluation=0006A1EE
Name=Sam Von
Organization=CCG
Registration #=67676767 <---假注册码
既然程序已将注册信息写入INI文件,于是用bpx getprivateprofilestringa来跟踪,在4AA479处程序已将以上信息读入内存,经过一段代码,程序用以上的版本号1.9f算出InstallCode和Evaluation,可能是安装时间和使用天数,这些不用理它,我们主要是找到算注册码的地方,下面是算法部分:
==Part I===========================================
之前的代码你会发现程序将我的注册名和组织名与字符串"Beyond Compare 1"连在一起变成"Beyond Compare 1Sam VonCCG",然后变成全大写.下面的代码将字串的每个字符做变形然后保存在原处,其中有3个分支,字符和数字分开处理,如果是空格就去掉.
0167:004A8CAF MOV EAX,[EBP-04] <---指向大写的字串
0167:004A8CB2 MOV BL,[EAX+ESI-01]<---第一位"B"
0167:004A8CB6 MOV EAX,EBX
0167:004A8CB8 ADD AL,BF
0167:004A8CBA SUB AL,1A
0167:004A8CBC JNC 004A8CDA <---判断字符or数字or空格
0167:004A8CBE LEA EAX,[EBP-04]
0167:004A8CC1 CALL 004040D0 <---不用进入
0167:004A8CC6 MOV EDX,[EBP-04]
0167:004A8CC9 XOR EDX,EDX
0167:004A8CCB MOV DL,BL
0167:004A8CCD SUB EDX,BYTE +41
0167:004A8CD0 ADD EDX,BYTE +0A
0167:004A8CD3 MOV [EAX+ESI-01],DL<---字符的处理
0167:004A8CD7 INC ESI
0167:004A8CD8 JMP SHORT 004A8D0D
0167:004A8CDA MOV EAX,[EBP-04]
0167:004A8CDD MOV EAX,EBX
0167:004A8CDF ADD AL,D0
0167:004A8CE1 SUB AL,0A
0167:004A8CE3 JNC 004A8CFE <---判断数字or空格
0167:004A8CE5 LEA EAX,[EBP-04]
0167:004A8CE8 CALL 004040D0 <---不用进入
0167:004A8CED MOV EDX,[EBP-04]
0167:004A8CF0 XOR EDX,EDX
0167:004A8CF2 MOV DL,BL
0167:004A8CF4 SUB EDX,BYTE +30
0167:004A8CF7 MOV [EAX+ESI-01],DL<---数字的处理
0167:004A8CFB INC ESI
0167:004A8CFC JMP SHORT 004A8D0D
0167:004A8CFE LEA EAX,[EBP-04]
0167:004A8D01 MOV ECX,01
0167:004A8D06 MOV EDX,ESI
0167:004A8D08 CALL 00404148 <---去掉空格
0167:004A8D0D MOV EAX,[EBP-04]
0167:004A8D10 CALL 00403F00 <---只是取原字串长度
0167:004A8D15 CMP ESI,EAX
0167:004A8D17 JNG 004A8CAF
最后我们得到数据:0B 0E 22 18 17 0D 0C 18-16 19 0A 1B 0E 01 1C 0A 16 1F 18 17 0C 0C 10 (已去掉空格),于是bpm这个地址,找到以下代码:
==Part II========================================
0167:004A180C PUSH EBX
0167:004A180D PUSH ESI
0167:004A180E PUSH EDI
0167:004A180F MOV EBX,EDX
0167:004A1811 XOR EDX,EDX
0167:004A1813 TEST CX,CX
0167:004A1816 JNA 004A1841
0167:004A1818 MOVZX ESI,DX
0167:004A181B MOVZX ESI,BYTE [EBX+ESI] <---数据第一位0B
0167:004A181F MOV EDI,EAX <---eax=0
0167:004A1821 SHR EDI,18
0167:004A1824 XOR ESI,EDI
0167:004A1826 AND ESI,FF <---保证esi为000000XX的形式
0167:004A182C MOV ESI,[ESI*4+004B8A4C]<---查表得到一个数
0167:004A1833 SHL EAX,08
0167:004A1836 XOR ESI,EAX
0167:004A1838 MOV EAX,ESI
0167:004A183A INC EDX
0167:004A183B DEC ECX
0167:004A183C TEST CX,CX <---循环完后eax=B8368083
0167:004A183F JA 004A1818
0167:004A1841 POP EDI
0167:004A1842 POP ESI
0167:004A1843 POP EBX
0167:004A1844 RET
看到程序的算法很简单,猜想eax的值就是注册码,退出后将eax转换成10进制,输入后提示错误,直接将它按字符形式输入,注册成功:-)
为了写注册机,我们必须得到程序数据表的内容,从4A182C处可以判断表长应为3F8位左右,dump下来,写出以下注册机.
==KeyGen===========================================
请将下面源程序保存为.rek文件,用注册机编写器编译,注册机编写器1.73测试通过!
