PS3 packages and how it leads to PSP signing

[Byte]

no.
see "pre-ipl hashing".

It appears Brokencodes was claiming that he/she found those unknown hashing function(s), it's obviously different from the KIRK stuff we've seen so far as Brokencodes' algorithm is based on the IDEA cipher not AES. Was Brokencodes just creating a smokescreen or was he/she really on to something?

One thing that doesn't add up is that DA was explaining that there's 20 bytes that are unknown, split up in 2 10-byte hashes, but Brokencodes is talking about 2 8-byte hashes.

Edit: some analysis on a ps2dev mirror:

Brokencode's hash was most likely fake.

Take a look at cNagra2::Signature in the source here:

I wonder why Sony would use that to protect their IPL.
And the "buff[8] &= 0x7F" will definitely not work in IPL

@m0skit0 I thought ever that Brokencodes is a guy from Datel who released the code for homebrew coders because they wanted to sell their blue pandora battery.

For running minis.

Lol? Just compile it twice -> Finish

[m0skit0]

lolwut?

[JJS]

I guess he means building the minis once for PSP and once for PS3 instead of writing a PSP emulator for PS3.

Ok, i successfully run "signed" homebrew on OFW 5.00, from memstick. 6.35 remains to test.
EDIT: oh yes, it wors on 6.35 OFW
