PS3 CFW 4.XX+ .PKG Resigner Script v0.3.1b by Zeroblu3 Arrives


76w ago - Hi all, with a guide and tutorial already posted, I finally decided to join the forum and share my PS3 CFW 4.XX+ .PKG Resigner Script v0.3.1b followed by v0.3.2b, v0.3.3b and v0.3.3b Fix1.

Download: PS3 CFW 4.XX+ .PKG Resigner Script v0.3.3b Fix1 / PS3 CFW 4.XX+ .PKG Resigner Script v0.3.3b / PS3 CFW 4.XX+ .PKG Resigner Script v0.3.2b / PS3 CFW 4.XX+ .PKG Resigner Script v0.3.2b (Mirror) / PS3 CFW 4.XX+ .PKG Resigner Script v0.3.1b / PS3 CFW 4.XX+ .PKG Resigner Script v0.3.1b (Mirror)

Actually this is my first post ^^ last night i just couldn't sleep so i started to play around with batch script and managed to make a little tool to automate the resigning process for <3.55 to >4.2.x

Code may look pretty raw but it should work. i tested a lot of homebrews and even some PSN games and it works. it's kinda late now and i worked almost all night on this so i didn't really have time to write a tutorial.

Just extract the folder in the rar somewhere on the pc and execute CFW 4.xx Resigner Script START.bat and follow the instructions in the cmd prompt. i'll write a detailed tutorial asap.

Meanwhile for questions and feedbacks my Twitter is z3roblu3

Let me know if you like it or hate it ^^ and if it works for you and have suggestions for improvements.

cya soon and have fun

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.

Eidtool is what we need, rest is useless I think
