Use, or subclass, me to implement a command that starts TLS.

Callers of StartTLS may pass several special arguments, which affect the TLS negotiation:

  • tls_localCertificate: This is a twisted.internet.ssl.PrivateCertificate which will be used to secure the side of the connection it is returned on.
  • tls_verifyAuthorities: This is a list of twisted.internet.ssl.Certificate objects that will be used as the certificate authorities to verify our peer's certificate.

Each of those special parameters may also be present as a key in the response dictionary.

Method __init__ Create a StartTLS command. (This is private. Use AMP.callRemote.)
Method _doCommand When a StartTLS command is sent, prepare to start TLS, but don't actually do it; wait for the acknowledgement, then initiate the TLS handshake.

Inherited from Command:

Class Variable arguments A list of 2-tuples of (name, Argument-subclass-instance), specifying the names and values of the parameters which are required for this command.
Class Variable response A list like arguments, but instead used for the return value.
Class Variable errors A mapping of subclasses of Exception to wire-protocol tags for errors represented as strs. Responders which raise keys from this dictionary will have the error translated to the corresponding tag on the wire. Invokers which receive Deferreds from invoking this command with BoxDispatcher.callRemote will potentially receive Failures with keys from this mapping as their value. This mapping is inherited; if you declare a command which handles FooError as 'FOO_ERROR', then subclass it and specify BarError as 'BAR_ERROR', responders to the subclass may raise either FooError or BarError, and invokers must be able to deal with either of those exceptions.
Class Variable fatalErrors like 'errors', but errors in this list will always terminate the connection, despite being of a recognizable error type.
Class Variable commandType The type of Box used to issue commands; useful only for protocol-modifying behavior like startTLS or protocol switching. Defaults to a plain vanilla Box.
Class Variable responseType The type of Box used to respond to this command; only useful for protocol-modifying behavior like startTLS or protocol switching. Defaults to a plain vanilla Box.
Instance Variable requiresAnswer a boolean; defaults to True. Set it to False on your subclass if you want callRemote to return None. Note: this is a hint only to the client side of the protocol. The return-type of a command responder method must always be a dictionary adhering to the contract specified by response, because clients are always free to request a response if they want one.
Class __metaclass__ Metaclass hack to establish reverse-mappings for 'errors' and 'fatalErrors' as class vars.
Class Method makeResponse Serialize a mapping of arguments using this Command's response schema.
Class Method makeArguments Serialize a mapping of arguments using this Command's argument schema.
Class Method parseResponse Parse a mapping of serialized arguments using this Command's response schema.
Class Method parseArguments Parse a mapping of serialized arguments using this Command's argument schema.
Class Method responder Declare a method to be a responder for a particular command.

Parameterstls_localCertificatethe PrivateCertificate object to use to secure the connection. If it's None, or unspecified, an ephemeral DH key is used instead.
