Below are the changelog and details, roughly translated:
- HMAC SHA-1 Added.
- Little Improvement of UI.
- Download of 3.21 / 3.30 Added.
- Preview of Updated_Files.tar Added.
To quote: "Critics I'll make sure to extract the files in Updated_Files.tar but it'll be good once more useless!
My program proposes the extraction of the same files... And gives you the HMAC that goes with allowing you to use!
By cons, for the repack, that is where the concern arises, you just give me a simple DOS command that lets you paste files with each other, the concern is that if you change even if one file, the HMAC necessarily change, so there you HMAC takes a file from another version and AC is set.
But the thing is that you have an HMAC of all the PUP, and therefore there like you can not recalculate your PUP is invalid.
So in any case, without calculating the HMAC key, nothing can repacker swapping or I do not know what files."
It means you can't create a custom pup using this software because you'll need encryption keys to repack it so ps3 validates yuur custom repacked pup as original, in other words this program can only decrypt pup it can not encrypt it again.
