+ * Each line in these files contains the following fields: markers

+ * The marker is optional, but if it is present then it must be one of
+ * ``@cert-authority'', to indicate that the line contains a certification
+ * authority (CA) key, or ``@revoked'', to indicate that the key contained
+ * on the line is revoked and must not ever be accepted. Only one marker
+ * should be used on a key line.
+ *
+ * Hostnames is a comma-separated list of patterns (`*' and `?' act as
+ * wildcards); each pattern in turn is matched against the canonical host
+ * name (when authenticating a client) or against the user-supplied name
+ * (when authenticating a server). A pattern may also be preceded by `!' to
+ * indicate negation: if the host name matches a negated pattern, it is not
+ * accepted (by that line) even if it matched another pattern on the line.
+ * A hostname or address may optionally be enclosed within `[' and `]'
+ * brackets then followed by `:' and a non-standard port number.
+ *
+ * Alternately, hostnames may be stored in a hashed form which hides host
+ * names and addresses should the file's contents be disclosed. Hashed
+ * hostnames start with a `|' character. Only one hashed hostname may
+ * appear on a single line and none of the above negation or wildcard
+ * operators may be applied.
+ *
+ * Bits, exponent, and modulus are taken directly from the RSA host key;
+ * they can be obtained, for example, from /etc/ssh/ssh_host_key.pub. The
+ * optional comment field continues to the end of the line, and is not used.
+ *
+ * Lines starting with `#' and empty lines are ignored as comments.
