OpenSSH public key line: the algorithm, a space, then the base64 body. A public key is not a secret, and it is a stable identifier of a person and of the machines they reach, which is what puts it here. The trailing comment, usually user@host, is left out: it is an email-shaped value the contact patterns already carry.
