Help me with encrypted data.pak file

[teusma]

I wanted to repack the game Car Jacker Hotwired and Gone but the data.pak file is encrypted - so files like .ogg .wav .dds do not compress efficiently with msc, oggre...

I can extract the files with quickbms but this script cannot reconstruct them back. I wanted someone to help me make a tool that decrypts and encrypts (CLI) this file.

Looking online I found a website (https://habr.com/ru/articles/689354/) where someone explains how to do this but I didn't understand anything. If anyone can help me I would really appreciate it. I really want to compress this data.

interesting topic about this file: https://web.archive.org/web/20220309...p=69458#p69458

the AI ​​claude told me that it is possible, using the quickbms script, to create a program in c++ (CLI) that has the function of decrypting and encrypting the data.pak file. but I don't understand anything about programming . so please, someone who understands programming do this for me, I beg you. Hahaha it was dramatic. it's serious!!! please!


I will leave the file for analysis:
