Finally, in related PlayStation 3 hacking news pink1 has made available an R2R+Edat tool followed by a R2R+edat v1.0.1 update with details below, as follows:

Here is a tool I put together. It's pretty much rap2rif, rif2rap and an edat fix tool for C00 type demos. Put your act.dat & idps in the data folder and you're ready for rap2rif & rif2rap. To fix C00 type demos input a .pkg from a C00 demo or the PARAM.SFO and it will output the fixed .edat.

This is a small update to R2R+edat, it fixes edats being a byte short & should speed up pkg2edat a lot by only decrypting the first 5MB instead of the whole pkg. Put your act.dat & idps in the data folder and you're ready for rap2rif & rif2rap. To fix C00 type demos input a .pkg from a C00 demo or the PARAM.SFO and it will output the fixed .edat.

Finally, in related PS3 EDAT news from BuC (aka BuC-ShoTz 1-2013) comes some old EDAT SRC Codes as follows: going through old stuff on my pc, for learning purposes i suppose.

seems like naehrwert found that hes SELFs are working on 3.56. And are working on a update of scetool yet again (0.1.1 doesent make valids - twitter.com/#!/naehrwert/status/153570111750545408)

  • no it seems 3.56 doesn't check for it, only 3.56+
  • But not generated by version 0.1.1, I'll release a fixed one soon!
  • apparently NPDRM SELFs generated by scetool DO work on 3.56 lol

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.
