April 18, 2013 // 4:08 am - Following up on his previous updates, today PlayStation 3 developer JjKkYu has released TrueAncestor EDAT Rebuilder v1.0 followed by v1.1 with details below.

Download: TrueAncestor EDAT Rebuilder v1.0 / UnEDAT.rar by RikuKH3 (Here's unedat tool, it decrypts any EDATs and you don't have to enter devklic key. Java and bcprov-jdk16-1.46 required.) / TrueAncestor EDAT Rebuilder v1.1

To quote: Finally, everyone can use this tool to decrypt and encrypt edat files on pc.

Thanks for KDSBest, JuanNadie, flatz, aldostool, BUC and other people I did not mentioned. Without their previous hard work I would not have made this tool.

TrueAncestor EDAT Rebuilder v1.0 Features

1. Decrypt and encrypt edat files on pc.
2. Fast rebuild mode.
3. Batch mode.
4. Dev Klic should be input manually at now.

If someone can make a command line bruteforce dec_klic tool for me, it would be fantastic.

Below is a video from Mustgaming andeverything showing you how to decrypt all PS3 dlc games (no need for any react psn anymore) with free dlc edat. This gui can decrypt and encrypt all kinds of edat and we can make our own fixes

v1.1 Changelog:

1. Fix JavaMemoryOut for encrypting big files.
2. Add JVM Memory config in tool\core.cfg.

ReActPSN does everything for you if you only want to play games or dlcs. Since edat can be decrypt now, we can get raw game data. It is more easy for people to edit the gamedata or create an unlock edat that has not been released officially. If you encrypt the file with improper dev klic, the edat file will not work. Some public dev klic you can use now:

2A6AFBCF43D1579F7D738741A13BD42E for Minis
52C0B5CA76D6134BB45FC66CA637F2C1 for PSX
72F990788F9CFF745725F08E4C128387 for Theme/C00 unlock edat
0DB85732366CD734FC879E743343BB4F for PSP Remaster

From capostef: Some klics I have found

Finally, in related PS3 homebrew news today PS3Game Info v1 is now released by Stephen88 (via ps3mod.altervista.org/T-PS3MOD-BETA-PS3GAME-INFO-V1-BETA?pid=74711#pid74711) who stated the following, roughly translated:

PS3Game Info is a simple PC program with which you can get a first impression of the characteristics of a certain game PS3, only to pull over the file PARAM.SFO! Here below the list of features that you can see about a game:

  • Internal disk (yes / no)
  • External disc (yes / no)
  • BD Mirror (yes / no)
  • Eboot Fix (yes / no)
  • Which Firmware required
  • External cache (yes / no)
  • Without disc (yes / no)
  • Updates (yes / no)
  • DLC (yes / no)
  • Size
  • True Blue (yes / no)

How does it work?

Information of each game are contained in a private database of PS3Mod, so you should expect excellent results. Since as you may have read in the title, this program is a beta, so please report me any deficiency / failure to improve the program and update the database! For Use: Drag the PARAM.SFO the game you want in the address box!

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.

Here is a follow-up from his blog today as well for those following: nwert.wordpress.com/2011/11/29/about-spu-channels-64-72-and-73/

If you are reversing the PS3′s isolated SPU modules, you will eventually notice channels 64, 72 and 73. Here are some C functions, that roughly describe how they work:

About SPU channels 64, 72 and 73

It seems that lv1ldr is storing it’s version into a special storage area.

And e.g. isoldr reads the version from the storage area and compares it to it’s own version. If the check fails, isoldr will just stop execution.

I wonder what else is stored in the area and how long the data in it persists, so my next idea is to code an isolated elf, that allows me to specify the value written to channel 64 and then dumps the data from channel 73.

Yep. WE mortals don't do nothing with this stuff. But i suppose it's an advancement about a free solution...

Oh, some news: And no, I won't release eidtool. If you want the algorithms, you'll have to start reversing

Cool, we can close this chapter too
