即时语音提示 & 校对软件InsTalk注册码及注册机-初学者请看

软件说明：即时语音提示&校对软件 InsTalk 是面向 Windows 9x/NT 的工具软件。利用它用户可以让电脑说汉语普通话。它有两种工作状态。一种是在使用键盘输入数字和英文字符时，可以跟随录入的字符即时发出相应的语音提示。另一种是让电脑朗读中文。

使用工具：TRW2000、PW32Dasm9b.EXE、KeyMaker。

由于受软件提示信息的影响，整个破解过程走了不少弯路：输入注册信息后，软件提示关闭并重新启动软件以验证注册码，但重新启动时，试了很多断点还是找不到注册码（其实可以找到，但此注册码并非你所输入的注册名和单位生成，而是注册名和单位为空时的注册码），后来通过对注册表的监视，当软件注册码错误时，程序根本就不往注册表里写入。所以，判断注册码的工作应该在输入注册信息的时候就已经进行了，作者给我们开了个大玩笑?!!

==========================================================================================
1、启动程序，填写注册信息，Ctrl-n，bpx hmemcpy，F5返回，按“注册”按钮，程序拦下。
2、bc *，pmodule。
3、按两次F10，来到下面：

==========================================================================================
4、以下是对程序重新启动后的一些分析：
程序一开始有个欢迎提示框，提示是共享版还是注册版，可见在此之前已经判断了是否已经注册，所以目的就是找出出现这个提示框的最后一个关键Call。
用trw2000载入InsTalk.exe，结合F10、F9、F6键就可找到这个Call（具体操作方法可参考我写的Acdsee4.0的破解，在看雪论坛以我的注册名esoft2001.51.net搜索就能找到）
:0041F76B 8B06 mov eax, dword ptr [esi]
:0041F76D 8BCE mov ecx, esi
:0041F76F FF5050 call [eax+50]（此处是出现提示框，应该快接近核心了。即使判断错也没关系，可以继续再试嘛!）
:0041F772 85C0 test eax, eax
:0041F774 7515 jne 0041F78B
==========================================================================================
F8进入上面的Call，看到下面代码：
:004046D0 6AFF push FFFFFFFF
:004046D2 68DD404200 push 004240DD
:004046D7 64A100000000 mov eax, dword ptr fs:[00000000]

……………………略去一些代码

其实通过分析我们已经可以看出，整个程序不论是注册时还是重新启动时都是在call 00404AC0里面进行核心的注册码判断，我们只要修改其中的一处就可变成注册版。并且从程序分析可知，全部比较完毕并且注册码正确时将跳到00404B2C，所以修改方法如下：
:00404B0E 3AD3 cmp dl, bl（这里改成cmp dl，dl即3AD3改为3AD2，自己比自己当然是一样的）
:00404B10 751E jne 00404B30（这里我们改成je 00404B2C，即将751E改成741A）
用二进制编辑工具打开InsTalk.exe文件，
查找：83C40C8A108A1E8ACA3AD3751E84C9
修改：------------------3AD2741A----

==========================================================================================
5、该软件的注册信息保存在注册表的以下位置：
HKEY_CURRENT_USER\Software\Happy Studio\INSTALK\Registration
HKEY_USERS\.DEFAULT\Software\Happy Studio\INSTALK\Registration
两个键下的四个二进制值（已加密变换）下：
Date:软件第一次运行的时间；试用期过后删除该二进制值可继续使用。
Date0:注册用户名称；
Date1:注册用户单位；
Date2:注册码。
用户注册后，删除Date0、Date1、Date2三个二进制值可重新注册。

==========================================================================================
6、编写注册机
使用“注册机编写器（Keymaker）”之“另类注册机”功能
(1)程序名称：InsTalk.exe
(2)添加数据：
　　中断地址：40749A
中断次数：1
　　第一字节：E8
　　指令长度：5

中断地址：404B05
中断次数：1
　　第一字节：83
　　指令长度：3

(3)选择内存方式EAX。

=======================================THE END=============================================
