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 i R/ R N( R R R R" t CERT_REQUIREDR R R R$ RR t TrueR2 t DEFAULT_CIPHERSR!

If none is provided, one will be created using :func:`create_urllib3_context`. :param ciphers: A string of ciphers we wish the client to support.
