[原创]Pocket CHM Pro 5.9另类破解~~~~

研究对象:Pocket CHM Pro 5.9
下载地址:自己搜索
软件介绍:这是用于在 CHM 格式创建帮助,电子读物或者手册的工具。袖珍的 CHM 能够直接打开和编辑 CHM 文件,和它能够反编译成批的 CHM。
涉及工具:OD,PEiD,stud_pe,WinHex

一、前言
最近在学习CAD的VBA,在明经通道上看到有在线的《ActiveX 和 VBA 参考》,想要CHM版的还要花30大洋,用OE把在线版的拉下来一看,乐了:居然正是完整的HTM版!自己编译成CHM版的不就OK了么!
但是正是这个编译过程让我郁闷了好半天。先找了个Microsoft HTML Help Workshop汉化版,一编译就出错;再找个国产软件QuickCHM试试看,编译出来的文件很多地方有问题,而且打开工程文件巨慢;最后找到这个PocketCHMPro,用起来感觉不错,但是未注册版只允许编译10个HTM页面。于是打算CRACK之!

二、开始CRACK:开始郁闷
先用PEiD查一下主程序PocketCHMPro.exe:Microsoft Visual C++ 6.0 [Overlay]到底还是2005年的东西,无壳,心中窃喜;进入输入注册码窗口,不输入任何东西直接点“OK”,弹出“User ID can not be empty”,居然还有错误提示,心中狂喜;直接用OD载入,查找字符串参考,没有找到任何有用的东西,字符串加密了?有点郁闷了;下断点“bp MessageBoxA”,没断下来,再下MessageBoxExA,GetDlgItemTextA,GetDlgItemTextExA之类的常用断点,还是没断下来,很郁闷了;直接暂停程序,再切换到程序界面,程序还在正常运行,查看一下任务管理器,居然还是双进程?相当郁闷了;任务管理器上显示新进程路径是“c:\Program Files\Pocket CHM Pro\PocketCHM_Pro.exe”,到目录下找到这个隐藏的主文件,直接运行弹出“程序执行错误”,极其郁闷了——居然还是双进程保护!

三、双进程调试:继续郁闷
先用OD分析一下真正的主程序PocketCHM_Pro.exe,果然不出所料,所有关键字符串都已经加密,几乎没有调用标准的API,我所知道的常用断点全部失效,静态分析没有找到有用信息;由于是双进程保护,只好开二个OD,一个调试主程序,另一个附加到PocketCHM_Pro.exe进行调试,却发现动态调试找不到下手的地方。看着程序总是在MFC.dll和pceeuilib.dll中来回转,我却只能一愁莫展,心里这个郁闷呀!
浪费了一二个小时后突然想到:MFC程序处理字符串时都会用到MFC42.#800_CString::~CString,MFC42.#858_CString::operator=等之类的函数,用这个用断点会不会有用呢?于是查找MFC42.#800_CString::~CString参考并在IAT处的JMP直接下断:
0046AB10  jmp     dword ptr [<&MFC42.#800_CString::~CString>]      ;  MFC42.#800_CString::~CString
输入用户ID和注册码后点击“OK”,终于断下来了!
观察堆栈:
0012E9EC   0042E26C  返回到 PocketCH.0042E26C 来自 <jmp.&MFC42.#858_CString::operator=>
在0042E26C处下断,再执行完二个RET后来到注册码处理过程:

[QUOTE=lelfei;447279]MFC程序处理字符串时都会用到MFC42.#800_CString::~CString,MFC42.#858_CString::operator=等之类的函数,用这个用断点会不会有用呢?于是查找MFC42.#800_CString::~CString参考并在IAT处的JMP直接下断:
0046AB10  jmp     dword ptr [<&MFC42.#800_CString::~CString>]      ;  MFC42.#800_CString::~CString
输入用户ID和注册码后点击“OK”,终于断下来了!
[/QUOTE]

请问 具体怎么操作?始终断不下来,反而出内存错误

直接在这一行按F2下断就可以了:
0046AB10 jmp dword ptr [<&MFC42.#800_CString::~CString>] ; MFC42.#800_CString::~CString

哈哈,给个安装程序.俺来跟跟.

看了一下你的程序,步骤都是对的,但是写的数据不对,你是不是在数据段里按CTRL+C复制出来的?把ASC值也复制到BIN文件里了!

我的做法是:先在数据窗口里跟随数据段,再在数据窗口里点鼠标右键——备份——保存数据到文件——保存即可!

是生成的程序,生成的那个程序才是真正的主程序,原安装程序只是起一个引导作用,了解作用后就可以把它放在一边了
