Well I'm unsure if this is the correct site to use but how would I go about decoding/decrypting PHP code which is encoded/encrypted using eAccelerator?

<?php
session_start();

how would I go about decoding/decrypting PHP code which is encoded/encrypted using eAccelerator?

You would have to reverse engineer the eaccelerator_load() function in eAccelerator.

Note that this function only exists in older versions of eAccelerator. For example, see here for the function as it existed in version 0.9.4: https://github.com/eaccelerator/eaccelerator/blob/e48010887b429a203bf03c7562e30a4d2bfa07d3/loader.c

The first thing the loader does is base64_decode() and gzuncompress() the string. You can see the (mostly plaintext) result of that here: http://ddecode.com/phpdecoder/?results=744654407d52841255a5b54c1d5b402d

It looks like restoring that to more readable code will take a bit more work with analyzing the eaccelerator_load() function, but I'm sure you'll be up to the task :)

  • I assume there's no 'tool' out there to do this? – prk Feb 18 '15 at 17:24
  • There's an online service for it: dezender.net/order/dezender/… – Jason Geffner Feb 18 '15 at 18:02
  • Yeah I found it too.. just that I'm a student and can't really afford the higher packages. /: – prk Feb 18 '15 at 18:46
  • 1
    That's why I recommended reverse engineering it instead ;) – Jason Geffner Feb 18 '15 at 19:04
  • @JasonGeffner not even, it's open-source, just take a look and make the decrypting program! :D – rev Feb 18 '15 at 19:36
