Well, the master key is out and about now so here’s a convenient little application to generate your dongle id keys.

Straight forward to use.

Linux only – will compile a Windows build if needed.

When I wrote this I hard-coded the revoke list on graf_chokolo’s wiki so credits to him and all of his hard work.

If you want source code, let me know – I’ll make a few changes – tidy it up and post it as well.

Mathieulh has updated his twitter with the real USB master key for the PS3 which was revealed by the PS3Yes team. (more…)

Notice: This news has been debunked as fake, XorLoser has closed his blog and is moderating his blog until further notice. There also are reports that the PSGrade project has been dropped too.

To quote Xorloser:

due to the ridiculous number of worthless posts, i have decided to moderate all posts for a while.

i will only be allowing only useful posts, that is posts that give actual information or ask actual meaningful questions. all other posts will go into the trash.

i will not allow any posts asking about when keys or other crap will be released. i will also not allow any “good work guys” style posts, not because i dont think the work is good, but merely because i dont want this comments section filling up with more uneeded posts that make it hard for ppl to find real info between.

since i will have to confirm every post, it may take a unmber of hours even for worthwhile posts to appear. this is because i have many other things better to do than to moderate posts 24/7. when i get time i will see about going back thru the existing posts and removing all the crap posts just leaving the useful ones. but this may or may not happen as my time is limited as it is. (if i had more time i would do useful things like more actual posts on this blog )

Looks like some things were too good to be true

Original Post:

Graf_choloko has sure been busy this weekend, and now I believe he has delivered the biggest bang to the PS3 scene since the PSJB . Graf_choloko has claimed that he has found the PS3 master key and has contacted zAxis to use with PSGrade.

I have dumped the key but will not make it public for now. I don’t want people developing more dongles and making more money off it

Don’t worry, I have contacted zAxis and he will use it for his PSGrade

@beavis

I know where you’re coming from and feel the same way but to be honest figuring this whole key thing out was interesting and that’s what motivated me

As for the 3.50 jailbreak, I have been working on any possible exploits or methods using one my original 3.15 and I have made some interesting progress

He has stated he will not release it publicly yet, but will be putting it to good use:

@norman

I was going to just post it here but like I said, I have contacted zAxis and asked him to keep it to himself for now

I plan to release publicly after PSGrade has become wide spread

Please understand

What a glorious day and weekend for the PS3 scene indeed.

Well its been done the ps3 master key has been decrypted via 3.41 firmware and no not by GRAF_CHOKOLO but by another member known as Estx. However he has not yet made his findings public as of today as he is still waiting for graf_chokolo to decrypt the master key but he has also informed that if graf has not yet decrypted the master key by tomorrow he will be making his findings public tomorrow. SO NOW ALL WE HAVE TO DO IS WAIT………

here is a quote from the site

I’ve found the Masterkey from bruteforcing dumps from my system.

Took 27 minutes, over 8,100,000 possible keys. Lol – could’ve waited but ah well.

If anyone is interested in doing the same, you can find it on 3.41.

for(int i = 0; i < list.length; i++)
if(HMAC-SHA-1(key[i]).ComputeHash(encryptChallengeBody) == matchResponseBody)
{
Success;
}

Challenge and response I took from the dumps reported on PSX-Scene.

If graf doesn't find it by tomorrow – I'll release the key.

Only reason I'm holding it back – is because no one helped me when I asked for it. (;

It’s just psuedo code. Actual code has a few more lines than this.

Inclusive of byte conversion, list generating from binary dumps and other trivial functions.

I have no way to dump the data between my at90usb192 and PS3 so I can’t post any challenge/response logs.

And it’s not a magic key – it is the master key.

I have tried it so far from 3.41 and 3.50 on my slim and fat.

That’s the actual loop there: #1346409 – Pastie

Prior to this is generation of the list etcetera.Originally Posted by phiren

I’m thinking more of the code which does an SHA1-HMAC between the master key and the dongle ID to generate the device key which is finally SHA1-HMACed with the challenge.

A single device key will work on all firmware versions, which makes it just as useful as the master key for our purposes.

It just means that Sony can revoke that single device and you can’t possibly generate another device key. But since Sony will probably revoke every single device and start again with a new master key with the next firmware version, having the master key isn’t that useful.Originally Posted by Estx

@phiren: That’s what I was thinking as I was learning how to generate the correct response before constructing a quick loop. The expected response is 20 bytes of what you suggested above.

I’ve found no other use of the master key yet.. so you’re quite right.

Mind you, I’m not as talented as some of the other developers here, I’m still playing around with new things I’m finding in the firmware’s. And thank’s to graf’s work – there’s even more to play around with.

TRUTH OR FICTION YOU BE THE JUDGE……………
