Hi, similar to rewold20 I also would like help finding the key for Prey Typhon Hunter: https://drive.google.com/file/d/1D4ho5E ... 9Ld1A/view

Prey uses CryEngine, but they switched to Unreal for their multiplayer/VR update. The pak assets appear to be encrypted because I can't extract them (runs out of memory) and the first ten lines of the .pak look like this: https://drive.google.com/file/d/1CgBZ1a ... PutIr/view

I've tried blindly using mmozeiko's aes-finder with no luck.

Could I possibly throw in a request for the AES key to The Blackout Club? If files are needed, I can happily supply...! :)

Hello!
Why nobody find aes key for sea of thieves ?
It’s so hard ?
They are no issues if it not static key ?
A genius somewhere ?

Thank, bye.

@tristo
Ok the problem happens only with quickbms 0.9.2.
It's not a real bug but it's more like a "feature" of "comtype copy" and a forgotten instruction.

For example let's say we want to create a file of 10 bytes by reading only 6 bytes and filling the remaining 4 with zeroes:

Code: Select all

comtype copy
clog NAME OFFSET 6 10

In the UE4 script we have a situation in which we need to read more bytes and writing less bytes which is no longer possible in 0.9.2 because it gave errors in some scripts.

It's something I can fix by handling the "aligned size" argument of the clog command but it requires a new version of quickbms and script.

In the meantime I have updated the script for working correctly with all the versions of quickbms, now and in the future :)

I can confirm Last Year: The Nightmare does not work, AES key is probably still from the beta.
Would be awesome if anyone can come up with one, i tried and failed

Are there any guides or anything on how to extract keys? I know C# and a bit of C++, assembly knowledge is limited but i have worked with some asm before, definetly not x86 tho.

You have to know aes encryption, reverse engineering and disassembly coding.I don't have any programming knowledge,so it's up to you

Hi guys! I need extract files from Dead by Daylight. Script Unreal Tournament 4 for QuickBMS didn't work anymore with new verions pak.
Any idea how I can do this?
Archive example https://www.mediafire.com/file/yt6ddq3i ... r.pak/file

UPD. All problems solved. It's my fault. I used new script with old version QuickBMS.

Hello! if its not a lot of trouble would it be possible to get the AES key for Ace Combat 7? I have the .EXE and the smallest .PAK in the file

http://www.mediafire.com/file/dwlouwje1 ... 7.rar/file

I thought I might get lucky and it would be the same key for Soul Calibur 6 but luck doesn't like me that way :P

@ssh, or anyone else who can find AES keys

Lineage 2: Revolution had an update recently and it requires an AES key to open the .pak files within Umodel. Are you 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.

Hope you or someone else can help me out,
Thanks in advance,

Try these:

0000803F1027000010270000FFFFFFFF0000803F0000803F0000803F0000803F

0x0000803F1027000010270000FFFFFFFF0000803F0000803F0000803F0000803F

C28F80D4C23B7B4B43C6704CC65A96532FC392D0D123F7E777CC949817D40AA7

0xC28F80D4C23B7B4B43C6704CC65A96532FC392D0D123F7E777CC949817D40AA7

may or may not work.
