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).
