twisted.protocols.tls._ContextFactoryToConnectionFactory

class documentation

class _ContextFactoryToConnectionFactory: (source)

Implements interfaces: twisted.internet.interfaces.IOpenSSLClientConnectionCreator, twisted.internet.interfaces.IOpenSSLServerConnectionCreator

View In Hierarchy

Adapter wrapping a twisted.internet.interfaces.IOpenSSLContextFactory into a IOpenSSLClientConnectionCreator or IOpenSSLServerConnectionCreator.

See https://twistedmatrix.com/trac/ticket/7215 for work that should make this unnecessary.

Method	`__init__`	Construct a `_ContextFactoryToConnectionFactory` with a `twisted.internet.interfaces.IOpenSSLContextFactory`.
Method	`clientConnectionForTLS`	Construct an OpenSSL server connection from the wrapped old-style context factory.
Method	`serverConnectionForTLS`	Construct an OpenSSL server connection from the wrapped old-style context factory.
Method	`_connectionForTLS`	Create an `OpenSSL.SSL.Connection` object.
Instance Variable	`_oldStyleContextFactory`	Undocumented

def __init__(self, oldStyleContextFactory): (source)

Construct a _ContextFactoryToConnectionFactory with a twisted.internet.interfaces.IOpenSSLContextFactory.

Immediately call getContext on oldStyleContextFactory in order to force advance parameter checking, since old-style context factories don't actually check that their arguments to OpenSSL are correct.

Parameters
oldStyleContextFactory:`twisted.internet.interfaces.IOpenSSLContextFactory`	A factory that can produce contexts.

def clientConnectionForTLS(self, protocol): (source)

from twisted.internet.interfaces.IOpenSSLClientConnectionCreator

Construct an OpenSSL server connection from the wrapped old-style context factory.

Parameters
protocol:`TLSMemoryBIOProtocol`	The protocol initiating a TLS connection.
Returns
`OpenSSL.SSL.Connection`	a connection
Note
Since old-style context factories don't distinguish between clients and servers, this is exactly the same as `_ContextFactoryToConnectionFactory.serverConnectionForTLS`.

def serverConnectionForTLS(self, protocol): (source)

from twisted.internet.interfaces.IOpenSSLServerConnectionCreator

Construct an OpenSSL server connection from the wrapped old-style context factory.

Parameters
protocol:`TLSMemoryBIOProtocol`	The protocol initiating a TLS connection.
Returns
`OpenSSL.SSL.Connection`	a connection
Note
Since old-style context factories don't distinguish between clients and servers, this is exactly the same as `_ContextFactoryToConnectionFactory.clientConnectionForTLS`.

def _connectionForTLS(self, protocol): (source)

Create an OpenSSL.SSL.Connection object.

Parameters
protocol:`TLSMemoryBIOProtocol`	The protocol initiating a TLS connection.
Returns
`OpenSSL.SSL.Connection`	a connection
