[PC] Lost Ark : .Upk / .lpk

[Salix]

Hello everyone, I was wondering how you could unpack and repack the stringdata.lpk file for Lost Ark.
The .lpk file is a compressed zip folder that has multiple XML files and a csv file.
Would appreciate any help!

Found a solution!

Given that the AES key is a 16 byte hex: 6310ba0b09cac5e67474c324052bbf48

is it possible to decrypt the file and repackage it back later?

LPK file: https://www.dropbox.com/s/szn6k2f4l3zs6 ... a.lpk?dl=0

@Salix
Uhmmm no.
The samples provided by other users are definitely not a ZIP file, it's clearly encrypted.

I have moved all the recent topics in this one since having 4 topics for the same thing is totally senseless...

Sorry, I have little knowledge about encryption! But this was the content of stringdata.lpk in CBT2 (after being decrypted).
File size became 10x bigger which made me think it's encrypted & compressed.

I only received the files back in CBT2

@Zexl. I would love an answer to this one as well, maybe you should ask this also at gildor.org forums. Maybe someone there knows what's causing this error.
