自己辛辛苦苦写的代码，总不希望被传的满天飞(除了自己愿意公开的除外)，那些有点特殊功能的程序总是要加密并做好授权，这样才能将自己的技术换个饭钱以便养活自己，那么程序猿们改如何做网站授权呢？大神可以忽略。今天分享的是别人的加密授权源码，被我解密；解密的多了，发现现在网站授权方式就那么几样，并且都是大同小异的，今天直接上代码，我们一起来研究下网站是如何进行授权加密的。

这个是个什么系统我并不清楚，没有详细跟踪，如果侵犯了您的隐私，留言我尽快删除。此系统是THINKPHP开发的:

作者不仅对该文件进行了简单的加密，并且对文件进行了MD5加密判断，只要修改了文件内容，就无法通过授权；这个软件你也就无法使用。
