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. .. _sni: https://en.wikipedia.org/wiki/Server_Name_Indication .. _crime attack: https://en.wikipedia.org/wiki/CRIME_(security_exploit) i ( t absolute_importN( t x509( t backend( t _Certificate( t timeoutt error( t BytesIO( t _fileobjecti ( t backport_makefile( t six( t utilt inject_into_urllib3t extract_from_urllib3t PROTOCOL_TLSv1_1t TLSv1_1_METHODt PROTOCOL_TLSv1_2t TLSv1_2_METHODc c@ s! | ] \ } } | | f Vq d S( N( ( t .0t kt v( ( sI /usr/lib/python2.7/site-packages/pip/_vendor/urllib3/contrib/pyopenssl.pys <genexpr>` s i @ c C@ sA t � t t j _ t t _ t t j _ t t _ t t j _ d S( s7 Monkey-patch urllib3 with PyOpenSSL-backed SSL-support.N( t _validate_dependencies_mett PyOpenSSLContextR t ssl_t SSLContextt HAS_SNIt Truet IS_PYOPENSSL( ( ( sI /usr/lib/python2.7/site-packages/pip/_vendor/urllib3/contrib/pyopenssl.pyR m s c C@ s: t t j _ t t _ t t j _ t t _ t t j _ d S( s4 Undo monkey-patching by :func:`inject_into_urllib3`.N( t orig_util_SSLContextR R R t orig_util_HAS_SNIR t FalseR ( ( ( sI /usr/lib/python2.7/site-packages/pip/_vendor/urllib3/contrib/pyopenssl.pyR y s c C@ s{ d d l m } t | d d � d k r7 t d � � n d d l m } | � } t | d d � d k rw t d � � n d S( s{ Verifies that PyOpenSSL's package-level dependencies have been met.
