Cannot decrypt games that don't require zRIF #15

Open Knurek-NC opened 6 years ago

Knurek-NC commented 6 years ago

There's a bunch of games in the NPS database that have NOT REQUIRED set for zRIF string. I'm guessing they all use a common key? How can one decrypt data from them?

@Knurek-NC Not sure what you mean. Can you give me some title names? I will investigate. @SilicaAndPina Btw - not sure if you are following commits or not. Savedata, trophies etc decryption is almost there. It already works. I just need to finish minor issues and will merge to master.

@motoharu-gosuto: Kai-ri-Sei Million Arthur (PCSG00750), Kin-Iro no Corda 4 (PCSG00774), Harukanaru Toki no Naka de 6: Gentou Rondo (3.61+!) (PCSG00975), Harukanaru Toki no Naka de 3 Ultimate (3.61+!) (PCSG00992), Kin-iro no Corda 2 ff (3.61+!) (PCSG01124) I'm interested in ripping the music out of them, but neither can be decrypted on PC, because your tool requires a zRIF argument to work.

@Knurek-NC Thanks. I will check later. Btw do these games have icv.db folder inside sce_pfs folder? If yes then I would suggest you to wait for a little longer. I am working on decryption of icv.db pfs format. It uses sealedkey instead of zRIF. Maybe this will help.

all games requires license for decryption. drm free pkg have license inside pkg - temp.bin

edit:

klicensees extracted from games you mentioned

@tomazzz369 It looks like the solution would be to implement extraction of klicensee from temp.bin ?
