Handles credentials extraction and challenges per request.
challengeProtocol
(Attribute)
A challenge protocol used by the plugin.
If a credentials plugin works with other credentials pluggins, it and the other cooperating plugins should specify a common (non-None) protocol. If a plugin returns True from its challenge method, then other credentials plugins will be called only if they have the same protocol.
