Everybody knows that if something was written and encrypted, it can be decypted and read.

So my question is that if you look at purely on PHP & Perl etc. "web app languages" what's the toughest encryption you can get? I know Ioncube is suppose to be hard but Syndk8's Autopligg was decoded in matter of hours when it came out so that wasn't very hard D'oh!

I'm asking because I might have situation coming where I have to leave one of my scripts in a place that's public and I'm looking for lightweight but very strong encryption. Of course the file still has to be executable.

if you are self encrypting your code, like running everything through an eval, then there is NO encryption that will help, since your keys need to be somewhere in the code.

using an off-the-shelf package can be a little better, in theory, but that now adds a requirement to your customers that they have that package installed.
I for example do NOT have ion installed, and probably never will. And frankly, they are ALL reversible.

You could do a binary PHP module (or whatever language you are targeting) but that is well outta my realm. And you would have to maintain for multiple OSs which would suck balls.

In the end, you might want to try a different approach. Think about how to capture your users, make then need you and a subscription, or something like that.
like Phantomaster. Yea, he probably gets a bit annoyed any time he sees his cloaker out there getting distro'd, but, its pretty useless without an IP database, which you need to subscribe to him for to get the full value out of the stolen software, so he makes his coin anyway.
