• @zecoxao has released siscon which is a Syscon firmware decrypter for PS4. I've checked the source code and it requires three key related files; sys-key, sys-iv and sys-cmac which are not included. However, some keys (mirror) where leaked in previous story about the PS4 Syscon.
    created this just for $#@!s and giggles. decrypts syscon fw updates from ps4 devkit consoles (you need to provide the keys yourself, but they're not hard to find)
