Hi!

your link gives a 404 error. But I think they blocked this hack with patch 1.4.

I'm trying really hard to increase the ammo of accessories (grenade launcher and gauss). Anyone figured it out? I tried EVERYTHING!!

ps: Thanks aluigi for your programm!
ps2: this site has the funniest method to avoid automated registrations!

Guys, yeah. The new crysis2.exe in the 1.4 patch uses patch1.pak as the main config pak, overriding all other paks. For example, your custom controls in the gamedata.pak won't be picked up unless the files in patch1 are changed.

Patch 1.8 released, but still the same problem: no valid key found.

Hi!

I've written a keygen script in QuickBMS for Crysis 2 to get the working key for patch 1.4 and later. It uses brute force mechanism so it will take a lot of time to get the correct key. If you want to help all you need is to download QuickBMS from here http://aluigi.org/papers.htm#quickbms and the keygen script from here http://dotyo.fw.hu/crysis2keygen.zip

Increase the starting value of i15 or i14 variables in the script (i.e. For i15 = 202 < 256) and start it with the command

quickbms.exe -w crysis2dec.bms patch1.pak output

Do not modify the "256" values!

In case QuickBMS won't start you can omit "patch1.pak output" and specify them using the open window of QuickBMS which will appear. "output" can be anything, as far as I know. The -w option is needed to create a TEMPORARY_FILE if the correct key is found. In case you found it, please e-mail it to me. Thanks.

If you would like to know which keys are used in the decoding attempts, set debug_mode to 1 or 2.

If you would like to test if the decoding works at all, use it on english.pak.

Of course breaking the encoding of Crysis 2 is against the EULA so only those should start this script who doesn't have Crysis 2 installed and/or know how to break such License Agreements.

I've included a userDefineLang.xml for Notepad++.

Good luck! For all of us.

it's a waste of time that leads to nothing because you can't bruteforce a key of 16 bytes, except if you have some centuries of time to wait :)

to be short the problem is simply that is needed a nocd exe of patch 1.4 or 1.8 because "as far as I know" the 1.0/1.1 one don't have the key for these patches.

I have a 200 megabytes test version of the game so maybe I'm wrong because it's not the full game anyway that's what I guess.

That´s all?

I will give you the links for testing *only* to the "cookys" @ PM

[aluigi]

oh cool 2 days ago the 1.8 nocd wasn't available.
maybe I'll give a look hoping my files are enough to reach the needed zone but it's not a problem because if it fails I'll give you the address where setting the breakpoint with ollydbg and retrieving the key.
stay tuned

[aluigi]

bad news.
I have checked the executable and the key is fixed in the executable (50b6c0) and there are no other functions that call the xxtea encryption algorithm.

so this is not just another key but there is something else like an additional encryption.
in short I give up.

but there is something else like an additional encryption.
in short I give up.

The cooky for "update 1.8" you can found for 10 days ago.

You sad a few post´s earlier, that the ENCRYPTION is "xxtea encryption with fixed key".

I search at I-NET about this and found

, but i understand....nothing.....

May you can.
