NP local license handling (C) 2012 by flatz

Setup:

  • /data/keys : Keyfile.
  • /data/ldr_curves : Loader curves (7744 bytes).
  • /data/vsh_curves : VSH curves (360 bytes).
  • /data/idps : IDPS as binary file
  • /data/act.dat : act.dat
  • /rifs/* : *.rif files
  • /raps/* : *.rap files

Keyfile format:

Keyset example:

NPDRM key(set) names:

  • [NP_tid]: Title ID OMAC1 key.
  • [NP_ci]: Control info OMAC1 key.
  • [NP_klic_free]: Free klicensee.
  • [NP_klic_key]: klicensee key.
  • [NP_idps_const]: IDPS constant.
  • [NP_rif_key]: rif key.
  • [NP_sig]: Footer signature ECDSA keyset.

Help text:

Version 0.2.7:

  • Added local NP license handling.
  • Added option to override klicensee.
  • Added option to disable section skipping (in SELF generation).

Regarding the PS3 SCETool Scripts (linked above): This is a nice little set of batch scripts that someone made to work along side SCETool.

Use the GETSELFINFO.bat to figure out what version your EBOOT (my copy of Resistance 3 was ver. 3.65) is which helped explain why some EBOOTs couldn't be modified. Don't forget to grab the Conent ID if you're changing the EBOOT from an update.

Finally, in related news keperfear has made a GUI for SCETool stating that you will need to have at least .Net 3.0 Framework installed to use it.

its for encrypt/decrypt any elf/self with the known keys so far (this will not work from selfs up to 3.55+) like Ezio says...
is mostly for development purposes.

It's just a great tool, a bit difficult to use for the average user. It is a multi-tool based on the fail0verflow tools and mainly it allows to encrypt/decrypt any elf/self with the known keys so far. I'm very glad the coder naehrwert makes it pubblic for all developers and not. I take this opportunity to thank him publicly.

what does the tool actually do though. I see my comment from the last update is just there.

I wouldn't really want to repeat myself, but yeah.. should have that info in there.
