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:
http://trac.eyetvcamd.ump2002.net/brows ... 2.cc?rev=1

I wonder why Sony would use that to protect their IPL. :?:
And the "buff[8] &= 0x7F" will definitely not work in IPL
GBASP x1, GBM x2, NDSL x2, PSP 100X x3, PSP 200X x6, PSP 300X x5, PSP Go x4, Wii x1

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