I posted the hash and it is allowed as it is not the actual key and is hard to work backfrom
sorry for not being so savy but is this anything in relation of what i asked yesterday about 4k updates exc?
Possiblly downgrade according to users who have knowledge back from in the ps3 scene..

Irony being you would need an entry point to use the keys to downgrade.... unless hardware will suffice?
Can't someone build a homebrew app from the ground up? *Cough*PSP HELLCAT FLASHER like*Cough*
To execute it you need an attack vector but a hardware atack would be much more likely but you would probably need to re flash the syscon and probably nor but the nor is encrypted so you would probably need a nor back up from a lower firm
These are the names of the keys that have been leaked.
FW_AES
FW_CMAC
PTCH_AES
PTCH_CMAC
RL78_ID
The PTCH_ keys are likely for "signing" patches. f0f blog says "Knowledge of the firmware updates keys means we can encrypt and sign our own patch files (it’s not explained in depth in this blog post - but syscon on retail PS4s is locked down to only support patching, not full update images)."
One thing to be wary of, they claim to have only looked at the rl78 on the earliest motherboard. The syscon on later motherboards may not have the same keys or schemes.

These are keys for updates for syscon, not for the ps4. I don't think this is enough on it's own for cfw.
Unless you have a launch ps4 then whatever is possible, may not work for you anyway.
"Most of our experimentation is conducted against the SAA-001 version of the PS4 motherboard. This is the initial hardware revision which was released around the end of 2013."

BigOnYa:
The switch emulators on pc rely on your CPU mostly, and they only use a single core, so GPU not as important as a good CPU. I don't use switch emulator, but many here do, and willing to help.

No you are not allowed to discuss them here, against the rules of the site. Sorry. But you can Google Nintendo NSP and there will be a few listed.
