@soatok@furry.engineer ah yes, the broadon/nintendo-approved (EC)DH implementation (as far as I understand it, broadon's implementation, used in over twenty years of consoles from the ique player to, last i checked, the nintendo switch, does the same thing, albeit this was only used to derive console-unique titlekeys for decrypting contents, one ECDH key came from fuses, the other came from RSA-signed data, so this was only useful on the ique player which doesn't have common tickets, for the same reason as "fix unable to decrypt message by setting your ecdh pubkey to all-zero")
