Object types: SSLSocket -- subtype of socket.socket which does SSL over the socket Exceptions: SSLError -- exception raised for I/O errors Functions: cert_time_to_seconds -- convert time string used for certificate notBefore and notAfter functions to integer seconds past the Epoch (the time values returned from time.time()) fetch_server_certificate (HOST, PORT) -- fetch the certificate provided by the server running on HOST at port PORT. No validation of the certificate is performed.

This object captures the state of an SSL connection but does not provide any network IO itself. IO needs to be performed through separate "BIO" objects which are OpenSSL's IO abstraction layer. This class does not have a public constructor. Instances are returned by ``SSLContext.wrap_bio``. This class is typically used by framework authors that want to implement asynchronous IO for SSL through memory buffers. When compared to ``SSLSocket``, this object lacks the following features: * Any form of network IO incluging methods such as ``recv`` and ``send``. * The ``do_handshake_on_connect`` and ``suppress_ragged_eofs`` machinery.
