HDD crypto

Can you say sector #0 on the hard drive which contains a partition table was encrypted with ATA keys only? Or with ENCDEC keys too? Because I tried to decrypt it on my PC with no success. I grabbed the individuals data from sb_iso_spu_module, then I encrypted them with my eid root key and then I ran AES-XTS-128 over the whole sector.

HDD sector#0 is encrypted with ATA keys only.

Hmm, thanks, this is weird then. Because I think that encrypting individual seeds with your root key is the same as dumping them from custom sb_iso_spu_module.

Thanks, glevand for the tip with the endianness hell! I successfully decrypted my HDD now.

How can compile from your posted asm_code our dump_ata_keys.self and dump_encdec_keys.self?

It's easy, i'll write a tutorial on ps3devwiki how to do it on Linux.

-I've a PS3 Slim model (CECH-3000 serie) with 4.21 firmware so i can't install custom firmware on it and also can't get keys. Is there, however, a means to decrypt my HDD (by using it on another ps3 with custom firmware for example)?

Nope, you can't do this. Because you lack of original keys from your 3K console and keys are not on HDD.

Gitorious

Hi :)

You can use gitorious for managing your coded stuff - highly recommended

Debian Live CD

Hey! maybe we should update the debian installation and live CD suff to wheezy since it has now reached a feature freeze! see: http://wiki.debian.org/DebianWheezy

tks for your time man...

Oh and btw for those of us without ss patches back in the 2.6 days there was dispmanager_access.sh whats the way to go now?

---

Not sure about Wheezy, i prefer to wait till release. Then i will update my livecd.

Regarding dispatcher manager script now. It's no problem, i see what i can do and upload a new script which works with new drivers.

ps3flash driver

Hi! I have a question about this driver. I've a NAND console (a really old one), and if I dump /dev/ps3flasha (with dd, for example), the output is not how it's suposed to be, I can't recognise anything, neither in Gentoo with 3.5.3 kernel nor in petitboot with 2.6.39.4 kernel. Recently, I tested a kernel with the old patches (/dev/ps3vflash* instead of /dev/ps3flash*), and this time in a /dev/ps3vflasha dump I could recognise some things like the 0FACE0FF DEADBEEF header, file tables... The size of both ps3vflasha and ps3flasha is exactly the same: 239M. I would like to know if it's correct or not. Maybe I miss some configuration... I don't know. Thanks!

The problem is wrong region flags on NAND. The new driver is used for both FLASH types: NAND and VFLASH.
Default region flags are for VFLASH because i have VFLASH.
You can change region flags when you load the kernel module like this:

insmod ps3flash region_flags=0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0

Default region flags are: 0x6, 0x2, 0x4, 0x4, 0x4, 0x0, 0x2, 0x0

I think for NAND the first region flag is not 0x6 but 0x2.
