域名授权与加密问题
现在有这么一套PHP系统,可以对指定的域名进行安装授权,未授权的域名则无法安装使用.

我的域名ipinge.com的安装授权文件(license.key)的内容为:

请问这种加密是如何实现的?
我现在要实现同样的功能,可以对指定域名生成license.key授权文件.


------解决方案--------------------
“生成授权文件”并不是要点,要点在于“如何使用授权文件”。

一般而言,应该是你那套“PHP系统”在什么地方来读取这个授权文件,从里面提取出指定的域名,再跟实际运行时的主机域名相比较。

至于这个授权文件本身,无非是对某些授权信息(当然包括指定的域名,也许会有用户信息、授权时间限制等等)进行某种可逆的编码转换。如果你的“PHP系统”没有经过混淆加密的话,读一下源程序,这些就很容易搞清楚了。
------解决方案--------------------
顶楼上,

最好读读php代码操作key文件那部分

不过我估计你php代码肯定混淆过了吧

zend很方便解密,百度一下就有好多解密工具

Ioncube加密 就麻烦了,前段时间研究过,国内国外转了个遍,没啥进展
