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`_). .. _sni: https://en.wikipedia.org/wiki/Server_Name_Indication .. _crime attack: https://en.wikipedia.org/wiki/CRIME_(security_exploit) .. _pyopenssl: https://www.pyopenssl.org .. _cryptography: https://cryptography.io .. _idna: https://github.com/kjd/idna � )�absolute_importN)�x509)�backend)�UnsupportedExtensionc @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r �F/tmp/pip-install-251nq386/pip/pip/_vendor/urllib3/contrib/pyopenssl.pyr ; s r )�BytesIO)�error)�timeout)� _fileobject� )�backport_makefile)�util)�six)�PROTOCOL_TLS_CLIENTz�'urllib3.contrib.pyopenssl' module is deprecated and will be removed in a future release of urllib3 2.x.

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. c S sp ddl m} yFx:dD ]2}| �|�r| t|�d� } |�d�|�| � S qW |�| �S |jjk rj dS X dS )z� Borrowed wholesale from the Python Cryptography Project.
