Last release: 2026-05-20

Certifi is a Python package that provides a curated bundle of Mozilla Root Certificates for validating SSL certificates and verifying the identity of TLS hosts. It is useful when you want a reliable, portable CA trust store for Python applications, and it does not support adding or modifying the certificates, so alternate trust should come from other tooling.

  • 2025.06.15

    2025-06-15

    This release (2025.06.15) does not include any release notes or change descriptions from the publisher. As a result, there is no documented information on new features, fixes, breaking changes, or dependency updates that could impact developers.
