i made a way to move a password or key from one device to another by scanning a QR code no account, no server of your own. it travels over public nostr relays, sealed with NIP-44 + NIP-59 so the relays can’t read it. both devices use throwaway keys that are destroyed after one transfer draft spec, not audited yet. please try to break it

QR Secret Transfer (QRST)

Move a secret from one device to another by scanning a QR code. No account, no server of your own, and the relays in between cannot read it.
