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.

the standard library ``ssl`` module supported SNI, but now that we've dropped
support for Python 2.7 all relevant Python versions support SNI so

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`_).
