TLS with SNI_-support for Python 2. Follow these instructions if you would
|
like to verify TLS 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:
|
|
.. code-block:: bash
|
|
$ python -m 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:
|
|
.. code-block:: python
|
|
try:
|
import pip._vendor.urllib3.contrib.pyopenssl as pyopenssl
|
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`_).

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.

Borrowed wholesale from the Python Cryptography Project. It turns out

that we can't just safely call `idna.encode`: it can explode for

wildcard names. This avoids that problem.
