OpenSSH certificate key types are not X.509 certificates, but a much simpler format that encodes a public key, identity information and some validity constraints and signs it with a CA key. CA keys are regular SSH keys. This certificate style avoids the attack surface of X.509 certificates and is very easy to deploy. Certified host keys allow automatic acceptance of new host keys when a CA certificate is marked as sh/known_hosts. see VERIFYING HOST KEYS in ssh(1) for details. Certified user keys allow authentication of users when the signing CA key is marked as trusted in authorized_keys. See "AUTHORIZED_KEYS FILE FORMAT" in sshd(8) for details. Certificates are minted using ssh-keygen(1), documentation is in the "CERTIFICATES" section of that manpage. Documentation on the format of certificates is in the file PROTOCOL.certkeys feedback and ok markus@
