Implementation of a TLS transport (ISSLTransport) as an IProtocol layered on top of any ITransport implementation, based on OpenSSL's memory BIO features.
TLSMemoryBIOFactory is a WrappingFactory which wraps protocols created by the factory it wraps with TLSMemoryBIOProtocol. TLSMemoryBIOProtocol intercedes between the underlying transport and the wrapped protocol to implement SSL and TLS. Typical usage of this module looks like this:
from twisted.protocols.tls import TLSMemoryBIOFactory
from twisted.internet.protocol import ServerFactory
from twisted.internet.ssl import PrivateCertificate
from twisted.internet import reactor
from someapplication import ApplicationProtocol
serverFactory = ServerFactory()
serverFactory.protocol = ApplicationProtocol
certificate = PrivateCertificate.loadPEM(certPEMData)
contextFactory = certificate.options()
tlsFactory = TLSMemoryBIOFactory(contextFactory, False, serverFactory)
reactor.listenTCP(12345, tlsFactory)
reactor.run()
This API offers somewhat more flexibility than twisted.internet.interfaces.IReactorSSL; for example, a TLSMemoryBIOProtocol instance can use another instance of TLSMemoryBIOProtocol as its transport, yielding TLS over TLS - useful to implement onion routing. It can also be used to run TLS over unusual transports, such as UNIX sockets and stdio.

TLSMemoryBIOFactory adds TLS to connections. |

TLSMemoryBIOProtocol is a protocol wrapper which uses OpenSSL via a memory BIO to encrypt bytes written to it before sending them on to the underlying transport and decrypts bytes received from the underlying transport before delivering them to the wrapped protocol. |
