[讨论中..] 感觉它的加密方式非常有特点，解了一半的软件，解不下去了。

目标：http://download.jgsoft.com/buddy/SetupRegexBuddyDemo.exe                    Version：3.0.3
简介：这个一个正则表达式工具，是我见过的最好的一款正则工具，这是一个试用版，但在功能上没有限制。为何说它的加密方式有特点呢，主要是时间限制，我感觉非常有特点。安装后，不管你向前还是向后调时间，都不会过期，只有在使用了7天以后，才会过期。不知道它是怎么做到这一点的，非常纳闷。

下面是我用peid查看该软件：Borland Delphi 6.0-7.0[OverLay]

关于它的nag窗口和自校验，我已经去掉：

但7天的时间限制不知道是怎么去掉的，这也是破这个软件最关键的地方，首先我不知道它的7天时间限制的思路，所以感觉下不了手。
现象：安装后，不管你向前还是向后调时间，都不会过期，只有在使用了7天以后，才会过期。过期后，卸载重装也没用，还是显示过期。

我感觉安装后的注册信息肯定是写到注册表中了，否则不会过期后，卸载重装也没用，还是显示过期。
我也尝试在读注册表的api处下断，但读的位置太多，无法搞清楚。

下面是安装这个软件后注册表中新增的信息，我用regshot工具记录如下：

Regshot 1.7

    1、如果程序安装后是通过注册表来控制使用的期限，那么应该找到这个注册表的键值，程序启动的时候必定会检测这个键值

    2、看下载的链接就是一个DEMO版，如果程序本身从代码上来设定使用7天，那么你可以搜索二进制的“7”看看有没有初始7天的地方，如果有改下。
