Thread: Euro Truck SImulator 2 - profile files

I have original file and compressed(+ maybe encrypted) file. Could someone take a look and even give me some idea what algorithm is used?
The structure of the encrypted file will probably (I'm not 100% sure) looks like this:

Code:

4 bytes - signature
16 bytes - HMAC key
32 bytes -HMAC
4 bytes - orginial size
...to the end - content

Im not expert about encryption, so I may be wrong
