There is clearly no encryption as visible from the first file of the archive.

Hmm, all i know is it gives me this if i set no encryption key



(0 files extracted on a 1.7gb .pak file)

the information that it is supposed to be encrypted comes from a developer

How were you able to tell that it has clearly no encryption?

Thank you for the quick reply!

Interesting, the files are non-encrypted but the TOC (the information about the stored files) apparently are obfuscated/encrypted.
It may be a custom solution of this specific game, for time reasons I will probably try to use a work-around by reusing the redundant information in front of each archived file. The only negative side is the lack of filenames.

Script 0.4.4.
Remember to rename the files with "unr" extension in "uasset".

Wow that was quick, thanks!

And yea that is a lot of .unr's .dat's and and .cl5's

It also seems like it just stopped at some point

Yeah, I didn't control the end.
I have updated it to version 0.4.4a for stopping when it reaches the end.

Still doesn't seem to end, not that it's much of a problem

also, and this might go out of the scope of this thread, but in the pak-samples archive i added a .sig file

it's apparently encrypted CRC's of every 128kb from the associated .pak file

is there a way to decrypt those? or rather generate one yourself so one can edit the .pak file and still be able to launch the game?

because the game doesn't seem to read any .uassets outside of the archive and i have no idea how else to mod the game

i would have sent you a PM regarding this to not go off-topic here but apparently that's not possible

sig is probably an RSA signature

And they probably haven't put the private key anywhere in the game files.. yea that sucks

As other guy asked how exactly you get the private key from a .pak? There's a new game that i'm trying to extract but some files are encrypted.

I just tried using your program for the first time but got an error, do you have any idea what's wrong?

This Unpacker was not updated for long time. For unpacking use QuickBMS UE4 script

His tool can just view Models / Textures. I am more interested to Modify the UI of that game, so it would require me to extract uasset or at least modify it some way. I think Umodel cant do that. At least I didnt find out .

With -export you cant extract Functions etc.

Are you sure that the archives are really encrypted?
Use http://aluigi.org/bms/filecutter.bms with a MEGABYTES variable set to 10 instead of 2 (open the script with a text editor), run the script on the big pak archive and upload the 2 files generated by it

Hello again, thank for reply.

So aain i test twinmotion 2018 , as you might now it uses UE core and it has such huge library of materials and models.
so i unpacked the pak file of gb, but when i opened it inside UE 4.16.2 and it just crash, i think the pak was cooked using older version v 4.15.1.
So does it really work if i try to open the library using 4.15.1 ?
