About types-certifi

from the package's own PyPI description — quoted content, verbatim

Typing stubs for certifi

This is a PEP 561 type stub package for the certifi package. It can be used by type-checking tools like mypy, PyCharm, pytype etc. to check code that uses certifi. The source for this package can be found at https://github.com/python/typeshed/tree/master/stubs/certifi. All fixes for types and metadata should be contributed there.

Note: The certifi package includes type annotations or type stubs since version 2022.5.18.1. Please uninstall the types-certifi package if you use this or a newer version.

See https://github.com/python/typeshed/blob/master/README.md for more details. This package was generated from typeshed commit 95128e61ec82c2ca8ec32d6c03bd9dad9ab68e65.

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Provides type stubs for the certifi package, enabling static type checkers like mypy and PyCharm to validate code that uses certifi.

Low install friction with no runtime dependencies. However, the package is stale—last released 2022-06-09 and now 1526 days old. The description notes that native type annotations have been available since version 2022.5.18.1, making this package potentially redundant.

Licensed under Apache-2.0 (permissive), allowing free use, modification, and distribution with minimal restrictions—suitable for both open-source and commercial projects.

Usage

pip install types-certifi==2021.10.8.3

This package is superseded by native type stubs available since 2022.5.18.1; the description recommends uninstalling types-certifi when using a current version.

Verdict: types-certifi is a lightweight, permissively licensed type stub package with no security vulnerabilities and active repository maintenance. However, it has not been updated since 2022-06-09 (1526 days ago), and the description explicitly notes that certifi has included native type stubs since 2022.5.18.1, making this package redundant for modern installations.
