This is a script for par-files from games in Origin.

Code: Select all

get ID long
if ID == 1007747626
	set POS 0
	set POS 4

encryption XOR "q@pO3o#5jNA6$sjP3qwe1"
get SIZE asize
math SIZE -= POS
log "decrypted_par.txt" POS SIZE
Does anyone know assignment of first 4 bytes of par-file?
Most likely it is a checksum.

You may want to check this.
It only results in gibberish in your tool.

How are the first 4 bytes calculated actually? Can anyone tell?

No, but I’ll bet it’s distinctive...that is I feel there have been others that have tried before to extract the files from the game.

Hmm, sadly none of the creators is reachable anymore. :(
