t.w.p.j.x.TLSInitiatingInitializer(BaseFeatureInitiatingInitializer) : class documentation

Part of twisted.words.protocols.jabber.xmlstream View Source View In Hierarchy

TLS stream initializer for the initiating entity.

It is strongly required to include this initializer in the list of initializers for an XMPP stream. By default it will try to negotiate TLS. An XMPP server may indicate that TLS is required. If TLS is not desired, set the wanted attribute to False instead of removing it from the list of initializers, so a proper exception TLSRequired can be raised.
Class Variableswantedindicates if TLS negotiation is wanted. (type: bool )
Method onProceed Proceed with TLS negotiation and reset the XML stream.
Method onFailure Undocumented
Method start Start TLS negotiation.

Inherited from BaseFeatureInitiatingInitializer:

Method __init__ Undocumented
Method initialize Initiate the initialization.
def onProceed(self, obj): (source)
Proceed with TLS negotiation and reset the XML stream.
def onFailure(self, obj): (source)
def start(self): (source)

Start TLS negotiation.

This checks if the receiving entity requires TLS, the SSL library is available and uses the required and wanted instance variables to determine what to do in the various different cases.

For example, if the SSL library is not available, and wanted and required by the user, it raises an exception. However if it is not required by both parties, initialization silently succeeds, moving on to the next step.
