This record is a draft: it has not been reviewed yet and may be incomplete or wrong. Do not rely on it for compliance decisions. Help improve it (see CONTRIBUTING.md).
Public key in the one-line OpenSSH format of authorized_keys and known_hosts files: the key type (ssh-ed25519, ecdsa-sha2-nistp256, ssh-rsa and others), a space, the Base64 of the RFC 4253 key blob and an optional comment, often user@host. The multi-line RFC 4716 format (---- BEGIN SSH2 PUBLIC KEY ----) and authorized_keys options before the key type are not covered.
