PS3 SCETool v0.3.1 by Habib Updated for Custom Fimware Users


26w ago - Following up on the previous updates and SCETool Script, today PlayStation 3 developer Habib (aka smhabib) who recently released Habib CEX 4.50 V1.03 PS3 CFW unofficially updated PS3 SCETool to version 0.3.1 for Custom Firmware users with the changes below.

Download: scetool v0.3.1.zip / SCETool v0.3.1 (with changes added) by zecoxao

To quote: Basically what it does is,it encrypts iso modules (needed for cfw creation!) with its respective indiv seeds of eid.now normal people can do amazing things.i first posted this on psx-scene but with not much details.SO HERE IT GOES WITH SRC!!!!

A short NOTE:the keys should be only edited with notepad++ to save its formating or you might get errors(latest keyset included!)

FOR N00BS: you can also use scetool --template spu_token_processor.self(original self) --sce-type=SELF --encrypt spu_token_processor.elf(modified elf) spu_token_processor.self(output modified self)

THANKS:

1. naehrwert
2. my friend anonymous dev

I SALUTE YOU BOTH!!!!!!!!!

CHANGELOG:

1. Fixed makefile
2. Added indiv seed options for creaters of cfw or for some testers

From zecoxao: Here is the tool on github (github.com/zecoxao/scetool) with all the added "changes" (which was commenting one line and uncommenting two, bravo...)

And here's an example of the new features being used: pastebin.com/Cw6uPiaJ

Check the label [Optional Header] for more information.

Finally, Habib has made available a proof-of-concept (PoC) for running syscalls based app without porting it to newer firmware with details below.

Download: POC.zip (2.18 MB)

To quote: Now I'll give you example of a Fan Control Utility being ran with my kernel and not with any other 4.50 cfw.if you try you'll simply get an error showing bad temp reading and sys_sm_get_fan_policy error. Currently source code is a lot a mess but ill be sharing it too.

Current Syscalls Added are: 386,389,409,383.

Here are a few quick updates from naehrwert (twitter.com/naehrwert) for those following:

  • haha just figured the eid3 algo, nice!
  • KaKaRoToKS and I added basic NPDRM support to scetool
  • SELF generation works now for SPU and PPU, except for compressing the data and NPDRM
  • added SPU SELF generation to scetool

Also from his site: nwert.wordpress.com/2011/12/24/individual-infos/

Individual Infos

One of the PS3′s console specific cryptography works as follows:

At factory time there is a console specific key generated, probably from a private constant value and a console specific seed. Maybe that’s the key used for encrypting bootldr and metldr. Fact is, that metldr stores another console specific keyset (key/iv) to LS offset 000000. That keyset is probably calculated from the first one. At factory time the isolated root keyset (how I call it) is used to encrypt the console’s “Individual Infos”, like eEID.

But not the whole eEID is encrypted the same way, special seeds are used to calculate key/iv pairs for the different sections. And not even that is true for every eEID section, because for e.g. EID0 another step is needed to generate the final section key(set). Each of the isolated modules using such an “Individual Info” has a special section that isoldr uses to generate the derived key(set)s.

But the generation works in a way, that the section data is encrypted with aes-cbc using the isolated root keyset, so it is not possible to calculate the isolated root keyset back from the derived key(set)s, because aes shouldn’t allow a known plaintext attack. So far I can decrypt some of EID0′s sections, EID1, EID2 and EID4. EID5 encryption should be similar to EID0′s but I lack the generation keys for that one.
