Copy Protection For PHP files?

[Diamond Damien]

I am looking for recommendations for the best PHP copy protection. The key feature in the copy protection is to able to be able give people UNIQUE serial numbers so that I can control who installs or uses the scripts on their web host. This way unauthorized users won't be able to install or run the program. Someone suggested this program: http://www.codelock.co.nz/tracker.html

What I need to happen... i.e.
1. Jimmy uploads the php files to his website
2. Jimmy runs the program and then it asks for a serial number
3. We give jimmy serial number and to unlock it so that the script will work
4 If Jimmy tries to give the script to his friend Teddy, Teddy won't be able to use the script since he needs the serial number which is unique for each person and can only be used one.

I assume you're already planning on using zend?

Yes I've considered Zen and IonCube

That codelock looks pretty good, and at that money...

Impressive features, I'll be interested in finding out either way what you go for.

actually I believe there are other ways to protect the scripts too if you would like to more pre-catious. I have a couple in mind that can be implemented. Will brainstorm a little more and perhaps PM it to you if it can be implemented (sorry cannot discuss on the open forums).

Cheers!!

Zend is a big no, it takes all of a few seconds to decode, same with codelock, byterun etc.

Zorex Cryptz has a public decoder out but it doesn't work so that is an option (you would need to code your own serial management but zorex will lock to ip and domain).

Ioncube is the most secure, while decodable the decoders are not in the public domain and the price and difficulty in decoding them is deterrent enough for all but the most determined.

just throwin this out there. i have coded my own licensing platform in php/mysql. it is capable of locking your software via domain and/or machine.
