Its seems that it is raining Master Keys, earlier Mathieulh found the PSP's Master Keys in the PS3, this means that the PSP is now as fully open as the PS3, here is a IRC log transaction from the source, im not a huge fan of posting IRC logs, but this is too awesome not too.

< @Mathieulh> thx sony xD
< +rck`d> psp crypto
< @Mathieulh> well it’s in ps3 but it’s psp keys

< @Mathieulh> lol
< @Mathieulh> yah
< @Mathieulh> has drm keyz too
< @dwrfcrank> Davee: Hey I told you it’s a isolated SPU module >:O
< @Mathieulh> so you can make your own psn store clone
< @Mathieulh> on psp

[07:47] < @Mathieulh> they are inside an isolated module
[07:47] Mathieulh, what file is the updater ?
[07:47] < @Mathieulh> which is inside a sprx

[07:48] not ps3
[07:48] < @Mathieulh> pup *
[07:48] kirk= The hardware crypto engine responsible for almost all aspects of the PSP’s security, including decryption of eboots & prx’s, savefile and adhoc encryption, and idstorage verification. Named after Captain Kirk of Star Trek.
[07:48] < @Mathieulh> ra you can sign psp apps
[07:48] even if he releases them there is no point
[07:48] which file ?
[07:48] < @Mathieulh> well “sign” xD
[07:48] < @Mathieulh> cause the signature is hmac-md5
[07:48] < @Mathieulh> while the encryption is AES128CTR
[07:49] Mathieulh, which file in the pup is the updater ?
[07:49] Mathieulh, just one question, how did you decrypt the sprx
[07:49] < @Mathieulh> darkhacke seriously…. it’s the only ****ing self in there
[07:49] < @Mathieulh> cooled_ I decrypted appldr
[07:50] like lv2_kernel.self icon razz Mathieulh Has Found The PSP Master Keys In PS3!

[07:50] < +jas0nuk> Mathieulh, start talking in french
[07:50] < @Mathieulh> (actually I pwned and dumped it first since I released the keys already)
[07:50] < @Mathieulh> then I looked for the keys
[07:50] ra, break kirk means that you can sign homebrew in user mode.. nothing of kernel mode…
[07:50] < @Mathieulh> grabbed them all
[07:50] no need be rude Mathieulh ):
[07:50] < @Mathieulh> used the one I needed to decrypt the sprx I knew had nice **** in
[07:50] and over 6.XX it’s easyly recokable
[07:50] < @Mathieulh> then I extracted the isolated module from it
[07:50] < @Mathieulh> then I decrypted/pwned isoldr
[07:50] < @Mathieulh> grabbed key
[07:51] < @Mathieulh> then decrypted the isolated module
[07:51] == Indy_ [~Indy@cpe-67-252-87-149.stny.res.rr.com] has joined #ps3dev
[07:51] < @Mathieulh> then I had all the keys + algos there

[07:51] < @Mathieulh> tadaa !

the keys are probably on the ps3 due to remote play.

Oh well. Im still waiting for some real CFW. Not debug firmware stuff.

Actually remote play doesn't utilize these keys, they're used for playing psp minis. CFW isnt really necessary anymore... maybe to install pkg files but you can do that with a proxy trick on a pc.

With this master key, could installing of PSP games occur?

Or reading ISO of our backuped PSP

Would so love to play my God of War for PSP on my big screen with PS3 controller.

Actually their is still a pertty good reason for cfw and that is for plugins,true animated custom theme overclocking and a lot of other option. :)

i assume you are talking about the ps3 and
last time i checked the proxy trick was patched a long time ago, if its the trick i am thinking of

touche, wasnt thinking about any of that (tired lol). Ya, running plugins like the psp would be amazing. Overclocking the ps3 wouldnt really be necessary at this point though. Even the most demanding commercial games dont really tax the cell processor that much... maybe once we get really good multitasking but until then I'll run default voltages.

Just use the service jig to install cfw, we should be able to make our own jig files ;)

If we can sign files, shouldnt the service jig not be necessary? If everything in a repacked .pup file is signed the ps3 shouldnt refuse it correct?

Good point. Just name the CFW PS3UPDAT.PUP and place it in /PS3/UPDATE on a memstick :)
