This installable Python package contains a CA Bundle that you can reference in your Python code. This is useful for verifying HTTP requests, for example.

This is the same CA Bundle which ships with the Requests codebase, and is derived from Mozilla Firefox’s canonical set.

Usage

To reference the installed CA Bundle, you can use the built-in function:

>>> import certifi

>>> certifi.where()
'/usr/local/lib/python2.7/site-packages/certifi/cacert.pem'

Enjoy!
