locker.public-keys@1: what anyone may read about a person's locker: the two public keys and the eight-word fingerprint. The fingerprint is the first eight bytes of SHA-256 over both public keys, read as eight words in two groups of four, joined by a middle dot, and the signature proves the holder owns the signing key, so a person can compare the eight words out of band and a key change is visible.
