By default, this function does a lot of the same work that ``ssl.create_default_context`` does on Python 3.4+. It: - Disables SSLv2, SSLv3, and compression - Sets a restricted set of server ciphers If you wish to enable SSLv3, you can do:: from urllib3.util import ssl_ context = ssl_.create_urllib3_context() context.options &= ~ssl_.OP_NO_SSLv3 You can do the same to enable compression (substituting ``COMPRESSION`` for ``SSLv3`` in the last line above). :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``. :param options: Specific OpenSSL options. These default to ``ssl.OP_NO_SSLv2``, ``ssl.OP_NO_SSLv3``, ``ssl.OP_NO_COMPRESSION``. :param ciphers: Which cipher suites to allow the server to select. :returns: Constructed SSLContext object with specified options :rtype: SSLContext iR/RN(RR RR"t CERT_REQUIREDRRRR$RRtTrueR2tDEFAULT_CIPHERSR!RR(R4R3R$R'tcontext((sA/usr/lib/python2.7/site-packages/pip/_vendor/urllib3/util/ssl_.pytcreate_urllib3_contexts#      c C@s|} | dkr*t||d|} n|s6| ry| j|| Wqtk rk} t| qtk r} | jtjkrt| nqXn(|dkrt| dr| j n|r| j ||nt r| j |d|St jdt| j |S(s All arguments except for server_hostname, ssl_context, and ca_cert_dir have the same meaning as they do when using :func:`ssl.wrap_socket`. :param server_hostname: When SNI is supported, the expected hostname of the certificate :param ssl_context: A pre-made :class:`SSLContext` object.
