Trying to clear up confusion (and since I haven't verified everything personally someone might have to clear up afterwards as well, and I realize I'm not able to keep this both technical and noobfriendly at the same time. Sorry):
- Geohot yesterday released a simple app, including a key, for decrypting PKGs. You'll find PKGs inside PUPs, and those we've already been able to unpack since before. Inside PKGs you'll find SELFs (and stuff) and those are encrypted as well, with a different key.
We cannot decrypt SELFs, at least not this way. We can ask the PS3 to do it for us, some with DeLiGhT's app and some using graf_chokolo's payload
- Waninkoko used Geohot's key to create an app that could both encrypt as well as decrypt PKGs. This does not change the fact that we cannot decrypt/encrypt SELFs though. It does mean we can take already encrypted/signed SELFs and make a new PKG with them mixed as we please.
When it comes to PUPs, I'm under the impression those don't need to be signed in recovery mode (that's why the PSjailbreak downgrade works)
(for those who like to reverse engineer it's said the PUP HMAC key can be found in vsh .. )
So. The key released yesterday is the symmetric key (AES) from inside lv2ldr?
Important Note: The encryption feature is not finished. It does all the encryption but the package headers (header, metadata...) are probably not filled with all the needed values (still need to guess what some stuff is for). I releases this source so devs can collaborate in this.
so what needs to be done now is... decrypt both 3.41 and 3.55.... find the patch that stops us using jailbreak.... take it out of 3.55... encrypt it back again and we can now jailbreak on 3.55 with psn etc etc....
wheres all the clever people at lol
HAPPY NEW YEAR ALL!
At the moment you can only decrypt and then encrypt back.
You cannot sign anything yet.
However as stated before i believe he (you know who) had the aes key all along and it kinda makes me believe that he is some how connected to the PSJailbreak.
As with the PSJailbreak you can flash a pup in service mode so how did they modify their pup in the first place??
With the current tools you can do that now, however unless you know what you are doing you will end up with a RSOD.
So did he hold back to make a few bucks???![]()
