A safe serial protection system?

Post by kaisellgren »

Hi,

I'd like to make a full and a lite version of my PHP+MySQL script. I have made a successful PayPal and serial number generation system, however, my script is too easy to crack as you just have to change a few values at db.

How would you make a hard to crack serial system? Can you provide me any links, I could not find any resources.

You might be interested in something like Zend Guard.
