Steam Deck Switch emulation - eviltoast

Hey so I installed Yuzu (and many other emulators) via emu deck so the installation is taken care of I think except for the product keys and title keys I have a switch but dont want to fuck with getting the keys out of it and all that so Im trying to just download them I found a website called “theprodkeys.com” is this legit? Sorry if its been mentioned somewhere before I no longer have access to reddit anymore so I cant check the megathread listed that links to reddit.
