the game is 4.27 so should be V11

repak.exe --aes-key 0x22B1639B548124925CF7B9CBAA09F9AC295FCF0324586D6B37EE1D42670B39B3 unpack pakchunk2-Windows.pak

It would be nice if repak unpack supported providing multiple input .pak files. Then you'd be able to combine it with bash globs or wildcards on the Windows cmd.

Example

repak.exe unpack -aes-key abcdef --out outdir *.pak

Right now, you have to write a for-loop for games with loads of paks.

pak version 12 support?

I just want to thank for these tools. Its working nicely and this is the best implementation of packing tool ever to be honest.

Are you also gonna support UE5 files ? Lastly could you please export the functions(unmanaged or managed) where i can utilize it in c# for example ?

like the title says Each time I try to open repak it completely closes not even a second after idk what to do rn can someone help and yes I have .net

I am writing a tool for unreal pak, but I encountered a decryption problem.

The key for unreal pak is AES256 of aWlpaWlpaWlpaWlpaWlpaWlpaWlpaWlpaWlpaWlpaWk=

The string before encryption is foo-bar seven characters

The encrypted string is 6c cc cd c8 60 8c 80 or 6c cc cd c8 60 8c 80 ef 69 8c 99 e4 a4 9a d5 ad?

But I used openssl's aes-256-ecb (not sure which one to use?) to encrypt foo-bar, which is a fixed 16 characters, so the decryption also fails.

openssl_encrypt('foo-bar', 'aes-256-ecb', base64_decode('aWlpaWlpaWlpaWlpaWlpaWlpaWlpaWlpaWlpaWlpaWk='), OPENSSL_RAW_DATA);
// bbe8d48c0f5b9aca2e460ed3253a67e3

Does aes-256 have non-block encryption?

Tested in Days Gone, using the latest repak.exe causes the pak contents to not be read, reverting back the exe fixes it

whenever i try to load a pak created with repak that uses any type of compression for a 5.1 game which uses paks i get this error

Often it is necessary to download a multi-gigabyte pak to troubleshoot problems that are often only in a few bytes in the index or footer. Creating a summary file that contains a few megabytes of the head and tail of the pak file should provide enough information to debug the majority of pak issues and would make sharing significantly easier.

Any plans on putting this crates.io?
I get that there's no docs right now but putting it on crates should be much lower effort.

Hello, I came across a file here that the repak utility cannot unpack. It was not located in the standard path, but in: *Game_Name\Content\Data*
The file itself can be unpacked perfectly using the standard UnrealPak v4.27. The file is not large, it takes up 1 MB

Here is the link to the file: https://drive.google.com/file/d/1Ub1lhlfTIoclcKzvzITKQt_ahosDYy7c/
