avphone3的破解
vb写的activeX控件,未注册会弹出注册窗口,加密方式太鬼了,user和product id保存在HKLM\SOFTWARE\Classes\CLSID\{D12BA6BB-0E5E-4879-B9E8-E7BFFA2C402D}\Control\Control下,以二进制数值存储,格式为 CA CF D3 CF C8 AB AC 97 94 95 92 93 90 91 9E 9F 96 AB AC A6 A6 A6 A6 A6 A6 A6 A6 A6 A6 A6 A6
算法很复杂,分析无望,想爆破,这是注册窗口中验证的部分

:42032019 处 0F 85 改为 0F 84,可以欺骗注册窗口
现在是 启动时他还会验证注册码的有效性,我想找到启动验证、弹出窗口的代码部分,可是找不到,他的字符串都是动态合成,由多个地方调用,我找找就晕了
求大虾们指点一下
另:
还有我的win98用trw2000载入文件调试,下完断点,一按F5就提示非法操作,trw2000就自己退了,在运行一次就死机
由于是调试activeX我不知如何用od下断点
