someone correct me if im wrong but aren't the riv/erk keys the only thing standing in the way of a cfw install from the latest fw (That or an exploit). With that, what is in the way of us obtaining those keys?

I've seen alot of talk about it, but nothing in real detail.

*facepalm* its lv0.2 and extra checks in 3.56+ that make it so even if we sign it right it wont run because firmwares modded and the extra checks make it so it wont run.

No... Well kind of. Bootldr2 and lv0.2 are what is in the way for unhackable consoles. 3.56+ firmwares have an updated HMAC key. That is what is in the way of doing a straight CFW install on a OFW hackable PS3 (without downgrading to 3.55).

Seriously you guys should let this thread die.This thread has one of the dumbest question i have seen today. I saw this started laughing then closed the thread to look into more important information.

Obviously not with your incredibly enlightening, post. i'm glad you stuck around bub. P.S. if you are trying to avoid stupid questions, the best way is to answer them, informed people don't ask stupid questions. not only that, it doesn't make you look like a prick either.

Do you think it will be quite a task to obtain said key?

You got to be kidding me, This is a Good question, One that Deserves an answer. You need to not be so Rude.

Perhaps only a matter of time now that 4.2X+ is getting cracked every which way, but it might take a while. Or maybe it will still be difficult.

I have seen a lot of post of lv0 being hacked that answer some of his questions. There was a post about appldr and getting the keys. Erk/ Riv need to be decrypted in order to have usable keys to decrypt new games etc... It has been mentioned before that we need private keys for OFW. Zadow has made dumps of lvl1 and lvl 2 in order to find exploits and i see no mention of erk /riv. Based on what i posted i find his to be a really dumb question that has been answered before in diferent threads on this site. I'll leave it at this since you guys are interested in knowing.

Riddle me this then, do the erk/riv keys matter to a firmware update?

I have been an onlooker for the past week as this has unfolded and it has not been mentioned to my knowledge. HMAC was the only thing I saw.

Dont quote me on this because my knowledge is limited but here is what i know.

All decription keys have a certain structure. That structure is composed by a set of keys (Keyset) and its components are ERK, RIV, PUB, PRIV and Curve Type. The ones we must have to decript are ERK, RIV and PUB. Thats why we couldnt decript LV0 before the complete leaking because if you remember, maybe a month ago, someone leaked the LV0 decription keys but he only leaked "erk" (if im not mistaken) so it was impossible to decript something with it and prove it was a real part of the keyset. It was only until this happened (http://www.ps3hax.net/2012/10/ps3-lv...d-and-working/) that we could actually try to decript something because we now have the complete keyset. They were proven real...but you know already the story.

Whenever we want to decript something, either a module or a signed package (signed with private key) we need their public Keyset with all the respective Keys.
Decription keys are indeed stored on appldr but i think i read zadow and other guys saying appldr keys were encripted with certain algorithm and thats why they havent released them yet.

About HMAC, the only thing i know about them is they are in isolated modules, they always decript (they dont encript) PS3 has differents HMAC's for PUP's and selfs and they are indeed used in firmware checksums.

All the game changes when we want to sign/encript. We need private key for that and we just have the 3.55 private key and below and we cant use them anymore on newer firmwares because they got on a blacklist and sony uses a new private key now...

If im wrong, let me know. I've had a great time learning about all this stuff
