So decompile that lib, extract the AES vector, and you can decrypt/encrypt all the save files you want. Surely I'm missing something, though :(
- mmozeiko 11y agoMost likely PS4 uses TrustZone implementation to operate with master key. AMD CPU's used in PS4 have smaller ARM CPU inside to support TrustZone. So you won't be able to simply dump keys from library or regular memory.
- SXX 11y agoHow exactly you want to decrypt file with vector only? Also you probably missing fact that browser process don't have access to the keyring; even to one that used for game saves. And there is likely several different key storages for different things just like it's was on PS3.
