reversing the key is not hard at all, eq2emulator project has a working closed source packet scanner that currently working, i`ve also redone Acid`s source code to work too.

You have a hard time getting anyone to share how to get the key, took me 2 months to determine how to get the key. the reason that no one is sharing the information, is that you could easy write a login (user/password) stealer once you know how to get the key.

i`ll give you a couple of hints, the key changes on each login and on each zone.
