Certifi: Python SSL Certificates

Certifi provides Mozilla’s carefully curated collection of Root Certificates for validating the trustworthiness of SSL certificates while verifying the identity of TLS hosts. It has been extracted from the Requests_ project.

Installation

certifi is available on PyPI. Simply install it with pip::

$ pip install certifi

Usage

To reference the installed certificate authority (CA) bundle, you can use the built-in function::

>>> import certifi

>>> certifi.where()
'/usr/local/lib/python3.7/site-packages/certifi/cacert.pem'

Or from the command line::

$ python -m certifi
/usr/local/lib/python3.7/site-packages/certifi/cacert.pem

Enjoy!

.. _Requests: https://requests.readthedocs.io/en/master/

Addition/Removal of Certificates

Certifi does not support any addition/removal or other modification of the CA trust store content. This project is intended to provide a reliable and highly portable root of trust to python deployments. Look to upstream projects for methods to use alternate trust.
