Homebrew Question How hackdiskmount verify the key?

[Alschepmist]

Hello do you know where in the emmc partition are the bis key saved? And it s possible to edit or read it like hackdiskmount do ? If i need hex editor where are the key stored?

Thanks

usually it does that by trying to decrypt the partition using provided biskey and see if the decrypted result has a valid signature (biskey is correct) or just complete garbage (biskey is wrong)

So it s not possible to edit the keys from 1 backup to fit in 1 console ?

 

[Garou]

I don't really get what you were asking

but I can tell you that hacdiskmount does not work like what you posted earlier

And it s possible to edit or read it like hackdiskmount do ? If i need hex editor where are the key stored?

Sorry for my english
My question is if i have a rawnand.bin can i change /edit the bis key or there is no way?

 

[Garou]

I don't think you can
theoretically you can decrypt using the old key and reencrypt using the new key, but I haven't seen anyone doing that

 

[Alschepmist]

Yes the problem is i don t know how to reencrypt that is the problem
