Instance Variable	secret	The shared secret used to authorized incoming component connections. (type: `unicode`.)
Method	__init__	Undocumented
Method	associateWithStream	Associate the authenticator with a stream.
Method	streamStarted	Called by the stream when it has started.
Method	onElement	Called on incoming XML Stanzas.
Method	onHandshake	Called upon receiving the handshake request.

Inherited from Authenticator (via ListenAuthenticator):

Instance Variable	xmlstream	The XmlStream that needs authentication (type: `XmlStream`)
Method	connectionMade	Called by the XmlStream when the underlying socket connection is in place.

The shared secret used to authorized incoming component connections. (type: unicode.)

def associateWithStream(self, xs): (source)

overrides twisted.words.protocols.jabber.xmlstream.ListenAuthenticator.associateWithStream

Associate the authenticator with a stream.

This sets the stream's version to 0.0, because the XEP-0114 component protocol was not designed for XMPP 1.0.

def streamStarted(self, rootElement): (source)

overrides twisted.words.protocols.jabber.xmlstream.ListenAuthenticator.streamStarted

Called by the stream when it has started.

This examines the default namespace of the incoming stream and whether there is a requested hostname for the component. Then it generates a stream identifier, sends a response header and adds an observer for the first incoming element, triggering onElement.

def onElement(self, element): (source)

Called on incoming XML Stanzas.

The very first element received should be a request for handshake. Otherwise, the stream is dropped with a 'not-authorized' error. If a handshake request was received, the hash is extracted and passed to onHandshake.

def onHandshake(self, handshake): (source)

Called upon receiving the handshake request.

This checks that the given hash in handshake is equal to a calculated hash, responding with a handshake reply or a stream error. If the handshake was ok, the stream is authorized, and XML Stanzas may be exchanged.
