My AES knowledge isn't perfect yet, but...
Try this: 0xF4393E55EE923AE2596931D85E1621FD96B11B509F2039809D66A60182BF5E82

No. Only if the methods get patched. It would get insta-patched if we shared it. Just post here when you need Keys and i Will get them for you.

That's on 4.19, My scripts are only really tested to work on 4.20 and onwards, so I can't promise anything on this file. But I will scan through it and see if I can find any possible keys.

Found 3 possible keys so far, scan can take hours, will add more if I find more.

Hi,
Can you find the Aes key for Satisfactory-Alpha-TestWeekend please? The files were sent by Rcjerome04 =>

File Cutter 1 -> https://www.mediafire.com/file/b6dr4gw7 ... 23199/file
File Cutter 2 -> https://www.mediafire.com/file/vg0e9y2b ... 23199/file
Big Exe -> https://www.mediafire.com/file/ml9rhlsi ... g.exe/file

The game has one .pdb and if we try to decompile the Big Exe it request if we want to locate the .pdb so if you need him i can upload him but it's 500mo.
Thank you for your help :)

Edit: I got the exe now. will come back with answer.

SATISFACTORY "POSSIBLE" AES KEYS:

AES: 0xFC338743E664E39BC6B90152A41737E649C9C508A4A75170B22B04D3C44DC48E

Thank you so much! I really want to learn the reverse engineering but it's hard alone ^^ If you can help me with some link of book or other that can be cool :)
Thx again :D

It took me about 1 year and 4 months to figure out how to get AES keys with relatively high success x) So it was a long battle.

Lineage 2: Revolution had an update recently and it requires an AES key to open the .pak files within Umodel. Is anyone willing to take a look?
I've extracted all 5 .pak files but I will upload 1, so you don't have to download a large chunck of files. If I need to provide other files, let me know.

You need to upload the main large exe called "gamename-x64"Shipped.exe
Also, your link was corrupted.

Are you refering to the EU version? I Just updated the KR one and no key is needed, game perfectly open with umodel on ue 4.12.

It's an Android game so no .exe, i remember a Gildor topic where he hinted for mobile game you needed the .pak and... maybe something else regarding the .dll, but i can't find the thread anymore -.-"

Yes I was refering to the EU Android version, the latest update from 2019-01-31. Requires a new Aes key.
https://apkpure.com/nl/lineage-2-revolu ... ble.lin2ws

Haven't tried the Korean version to be honest. What are the differences between EU and korean version besides the language?

So yes there is no .exe i guess. I can provide .pak files. This is the smallest .pak file from the EU version, hopefully someone can find the new aes key. Or should I upload other files as well?

Smallest .pak file:

GHFear, would I be able to persuade you to take a shot at this one? It's Last Year. I zipped the exe to make it a little lighter...

Someone posted this key 0x813EDABA7C6E44A6EBD09CBC8F6C9F9B2CCB2242D654E14D5F762E1A079EEE69
the other day. have you tried it? I can scan through it too to make sure tho.

Edit: got the same key in about a minute, so should be that. :]
