- Sets a restricted set of server ciphers

:param ssl_version:
The desired protocol version to use. This will default to
PROTOCOL_SSLv23 which will negotiate the highest protocol that both
the server and your installation of OpenSSL support.
:param cert_reqs:
Whether to require the certificate verification. This defaults to
``ssl.CERT_REQUIRED``.

``ssl.OP_NO_SSLv3``, ``ssl.OP_NO_COMPRESSION``.
