is there a FREE php cripted source decripter (zend, ioncube,....)?? i've only found deZender but is too expensive
Why would you want to do this anyway? The script author probably has a reason why he encrypted his code.
You're trying to decrypt an encrypted script? If you're just trying to decrypt it to run it then zend and ioncube both have free decrypters. Encrypting them is what costs money.
Umm...I suspect reverse-engenering... That's the worst a developer can get, but there's nothing you can do. When I was a java developer in 95-98, all and almost every application have been decoded to be plagiarized...very sad since it took 1 month to code and 1 minutes to decode and copy...and changing the copyright!!
What sort of "encryption" is it? Most of those source hiding attempts are quite frail and trivially reversed. Post a link to the script?
