Defaults to :data:`ssl.CERT_NONE`. If given a string it is assumed to be the name of the constant in the :mod:`ssl` module or its abbrevation.

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 Nr r5 Tr) F) r% r* r Z CERT_REQUIREDr r r! r- rO r7 �DEFAULT_CIPHERSr+ r) )r9 r8 r- r0 �contextr r r �create_urllib3_context� s # rV c C s� |} | dkrt |||d�} |s"| r�y| j|| � W q� tk r\ } zt| ��W Y dd} ~ X q� tk r� } z | jtjkr�t| ��� W Y dd} ~ X q�X n|dkr�t| d�r�| j� |r�| j ||� t r�| j | |d�S t j dt� | j | �S )a 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. 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. This is not supported on Python 2.6 as the ssl module does not support it. :param ca_cert_dir: A directory containing CA certificates in multiple separate files, as supported by OpenSSL's -CApath flag or the capath argument to SSLContext.load_verify_locations(). N)r0 �load_default_certs)r= a� An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform. This may cause the server to present an incorrect TLS certificate, which can cause validation failures. You can upgrade to a newer version of Python to solve this.
