AUTHORIZED_KEYS FILE FORMAT AuthorizedKeysFile specifies the files containing public keys for public key authentication; if this option is not specified, the default is ~/.ssh/authorized_keys and ~/.ssh/authorized_keys2. Each line of the file contains one key (empty lines and lines starting with a ‘#’ are ignored as comments). Public keys consist of the following space-separated fields: options, keytype, base64-encoded key, comment. The options field is optional. The supported key types are:
[email protected] ecdsa-sha2-nistp256 ecdsa-sha2-nistp384 ecdsa-sha2-nistp521 [email protected] ssh-ed25519 ssh-dss ssh-rsa
The comment field is not used for anything (but may be convenient for the user to identify the key).
