I am a coder and i just wrote a new PHP app, so i was looking at Zend, IonCube, CodeLock and the usual to protect my "stuff". I can decode some of them myself, some apps i really ask myself how retarded the encryption must be (Code Lock ) if i can decode it myself without even using a 3rd party tool. I find a pretty "ok" one which is called "Source Lock"..."ok" since i already tried to decrypt one of the files myself and couldnt do it. It also supports locking by IP/domain (which i needed)...and it is only EU59, extremely easy to use. I am not related to them, but check it out if you look for a good PHP enrypter which is AFFORDABLE. (not hundreds of $$$ like Zend which every 5 year haxor can encrypt already sourcelock.biz The only problem i had with them it took them a few hours to process my order, but i am REALLY satisfied with this thing for not even 60 bucks!
