This module provides some more Pythonic support for SSL.
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())
get_server_certificate (addr, ssl_version, ca_certs, timeout) -- Retrieve the
certificate from the server at the specified
address and return it as a PEM-encoded string
Integer constants:
SSL_ERROR_ZERO_RETURN
SSL_ERROR_WANT_READ
SSL_ERROR_WANT_WRITE
SSL_ERROR_WANT_X509_LOOKUP
SSL_ERROR_SYSCALL
SSL_ERROR_SSL
SSL_ERROR_WANT_CONNECT
SSL_ERROR_EOF
SSL_ERROR_INVALID_ERROR_CODE
The following group define certificate requirements that one side is
allowing/requiring from the other side:
CERT_NONE - no certificates from the other side are required (or will
be looked at if provided)
CERT_OPTIONAL - certificates are not required, but if provided will be
validated, and if validation fails, the connection will
also fail
CERT_REQUIRED - certificates are required, and will be validated, and
if validation fails, the connection will also fail
The following constants identify various SSL protocol variants:
PROTOCOL_SSLv2
PROTOCOL_SSLv3
PROTOCOL_SSLv23
PROTOCOL_TLS
PROTOCOL_TLS_CLIENT
PROTOCOL_TLS_SERVER
PROTOCOL_TLSv1
PROTOCOL_TLSv1_1
PROTOCOL_TLSv1_2

The message callback provides a debugging hook to analyze TLS
connections. The callback is called for any TLS protocol message
(header, handshake, alert, and more), but not for application data.
Due to technical limitations, the callback can't be used to filter
traffic or to abort a connection. Any exception raised in the
callback is delayed until the handshake, read, or write operation
has been performed.
def msg_cb(conn, direction, version, content_type, msg_type, data):
pass
conn
:class:`SSLSocket` or :class:`SSLObject` instance
direction
``read`` or ``write``
version
:class:`TLSVersion` enum member or int for unknown version. For a
frame header, it's the header version.
content_type
:class:`_TLSContentType` enum member or int for unsupported
content type.
msg_type
Either a :class:`_TLSContentType` enum number for a header
message, a :class:`_TLSAlertType` enum member for an alert
message, a :class:`_TLSMessageType` enum member for other
messages, or int for unsupported message types.
data
Raw, decrypted message content as bytes

implemented by OpenSSL. 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, including methods such as ``recv`` and ``send``.
* The ``do_handshake_on_connect`` and ``suppress_ragged_eofs`` machinery.
