SSL with SNI_-support for Python 2. Follow these instructions if you would
like to verify SSL certificates in Python 2. Note, the default libraries do
*not* do certificate checking; you need to do additional work to validate
certificates yourself.

This needs the following packages installed:

* pyOpenSSL (tested with 16.0.0)
* cryptography (minimum 1.3.4, from pyopenssl)
* idna (minimum 2.0, from cryptography)

However, pyopenssl depends on cryptography, which depends on idna, so while we
use all three directly here we end up having relatively few packages required.

You can install them with the following command:

    pip install pyopenssl cryptography idna

To activate certificate checking, call
:func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code
before you begin making HTTP requests. This can be done in a ``sitecustomize``
module, or at any other time before your application begins using ``urllib3``,
like this::

    try:
        import urllib3.contrib.pyopenssl
        urllib3.contrib.pyopenssl.inject_into_urllib3()
    except ImportError:
        pass

Now you can use :mod:`urllib3` as you normally would, and it will support SNI
when the required modules are installed.

Activating this module also has the positive side effect of disabling SSL/TLS
compression in Python 2 (see `CRIME attack`_).

If you want to configure the default list of supported cipher suites, you can
set the ``urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST`` variable.

    Converts a dNSName SubjectAlternativeName field to the form used by the
    standard library on the given Python version.

    Cryptography produces a dNSName as a unicode string that was idna-decoded
    from ASCII bytes. We need to idna-encode that string to get it back, and
    then on Python 3 we also need to convert to unicode via UTF-8 (the stdlib
    uses PyUnicode_FromStringAndSize on it, which decodes via UTF-8).

    If the name cannot be idna-encoded then we return None signalling that
    the name given should be skipped.
