Resolves the argument to a numeric constant, which can be passed to
the wrap_socket function/method from the ssl module.
Defaults to :data:`ssl.CERT_REQUIRED`.
If given a string it is assumed to be the name of the constant in the
:mod:`ssl` module or its abbreviation.
(So you can specify `REQUIRED` instead of `CERT_REQUIRED`.
If it's neither `None` nor a string we assume it is already the numeric
constant which can directly be passed to wrap_socket.

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 pip._vendor.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

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.
: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().
:param key_password:
Optional password if the keyfile is encrypted.
:param ca_cert_data:
Optional string containing CA certificates in PEM format suitable for
passing as the cadata parameter to SSLContext.load_verify_locations()
