[GET] PHP Crackme.. Test Your Skills!

[NOP]

so, I'd like all the crackers around here to have a go at my nice little php crackme! (just testing the effectiveness of a nice little php obfuscator i've been coding)

You need to find the serial, and send it in a GET request like:

crackme.php?serialgoeshere

(POST should also work too!)

This will give you another string, go PM that to me with a screenshot, and i'll add your name to the list of those who have completed it!

..and here is the crackme!

Code:

Users who completed it:

Code:

Very cool. Above the few brain cells I have left in my ole head but sure like to see the end result if you plan on sharing obfuscator.

Looking for a way to encode some PHP scripts. Not that any encoding is completely safe, but, as my old man told me many years ago: locks are only made to keep honest people honest:)

I always look at the new message on this board (View New Posts)! Because I cracked many application in the past (not PHP), the word "Crackme" was that caught my attention !

I meant.. how easy was it to solve for you?

I reformat code with PHPStorm, I "splitted" in several functional parts, find/replace, study and get decoded file. It took me 2-3 hours !

yeah um, that eval() isn't the only layer. in fact i only added the eval() to get the file size down.
