Is there an easy way to encrypt a string so that I can pass it to a .php which decrypts it?
Just a simple function which is fast and does not simply replace character n with x (I want to encrypt a URL so by using this simple replacement method would lead to http:// -> abbcdee for every url which is quite obvious).
I know that this isn't safe at all because it will be implemented in a local user client script but it's about increasing the effort for using my .php by someone who hasn't got my script.
