Muh Switch Keys
So you want to decrypt switch content ? Well, the good news is that all the tools required to do that are written up! The great news is, since this is crypto we're talking about, you'll have to find the keys. Yourself. Like it's easter.
So here you can find a template of the
$HOME/.switch/prod.keys file that hactool uses to decrypt content. It contains all the SHA256 and location of the keys and seeds, so you can find them yourselves.
Note that all the seeds (the keys that end with
_source) are used along with the
master_key_## to derive an actual key.
If you have somehow obtained the key without the seed, you can rename
xxx_## (where ## is the master key number) and put your key there.
