--------------------------------------------------------------------------------
【破解内容】 声明:这是Camtasia Studio 目前最新的版本,它提供了两种类型的注册码
一种是18位的注册码,一种是25位的注册码,这里的18位的用了md5算法,
之于这里的代码我就没给出了,因为它是与snagit 相同,感兴趣的朋友可以去
参考我写的snagit v7.01的破解教程,之于那计算25位的注册码是什么算法
我就不知道了,反正是很复杂的,我算法好久还是没找出什么来。
下面开始吧!
-----------------------------
我们现在有了破解snagit的经验了,我们可以直接找ascll "RegisteredTo" 来到下面这里
