See the documentation of the Message class for a complete description of the keyring dictionary. *zone*, a ``dns.name.Name`` or ``text``, the zone which is being updated. *rdclass*, an ``int`` or ``text``, the class of the zone. *keyring*, a ``dict``, the TSIG keyring to use. If a *keyring* is specified but a *keyname* is not, then the key used will be the first key in the *keyring*. Note that the order of keys in a dictionary is not defined, so applications should supply a keyname when a keyring is used, unless they know the keyring contains only one key. *keyname*, a ``dns.name.Name`` or ``None``, the name of the TSIG key to use; defaults to ``None``. The key must be defined in the keyring. *keyalgorithm*, a ``dns.name.Name``, the TSIG algorithm to use.
