  "github_readme_excerpt": "Certifi: Python SSL Certificates\n================================\n\nCertifi provides Mozilla\u0027s carefully curated collection of Root Certificates for\nvalidating the trustworthiness of SSL certificates while verifying the identity\nof TLS hosts. It has been extracted from the `Requests`_ project.\n\nInstallation\n------------\n\n``certifi`` is available on PyPI. Simply install it with ``pip``::\n\n    $ pip install certifi\n\nUsage\n-----\n\nTo reference the installed certificate authority (CA) bundle, you can use the\nbuilt-in function::\n\n    \u003e\u003e\u003e import certifi\n\n    \u003e\u003e\u003e certifi.where()\n    \u0027/usr/local/lib/python3.7/site-packages/certifi/cacert.pem\u0027\n\nOr from the command line::\n\n    $ python -m certifi\n    /usr/local/lib/python3.7/site-packages/certifi/cacert.pem\n\nEnjoy!\n\n.. _`Requests`: https://requests.readthedocs.io/en/latest/\n\nAddition/Removal of Certificates\n--------------------------------\n\nCertifi does not support any addition/removal or other modification of the\nCA trust store content. This project is intended to provide a reliable and\nhighly portable root of trust to python deployments. Look to upstream projects\nfor methods to use alternate trust.\n",

It bundles Mozilla\u0027s CA certificates in a portable, version-pinned format so your Python scripts trust the same roots across environments without relying on system cert stores. Essential dependency for any Python code making HTTPS requests."
