Truststore is a library which exposes native system certificate stores (ie "trust stores")
through an `ssl.SSLContext`-like API. This means that Python applications no longer need to
rely on certifi as a root certificate store. Native system certificate stores
have many helpful features compared to a static certificate bundle like certifi:

- Automatically update certificates as new CAs are created and removed
- Fetch missing intermediate certificates
- Check certificates against certificate revocation lists (CRLs) to avoid monster-in-the-middle (MITM) attacks
- Managed per-system rather than per-application by a operations/IT team
- PyPI is no longer a CA distribution channel 🥳

Right now truststore is a stand-alone library that can be installed globally in your
application to immediately take advantage of the benefits in Python 3.10+. Truststore
has also been integrated into pip 24.2+ as the default method for...

## AI interpretation — verify before relying

Truststore exposes native system certificate stores through an ssl.SSLContext-like API, allowing Python applications to verify HTTPS certificates using the operating system's trust store instead of relying on bundled certificate files.

Verdict: Truststore is a production-ready, zero-dependency library that modernizes Python's certificate verification by leveraging native system trust stores. Its MIT license and top-1000 popularity make it a solid choice for applications targeting Python 3.10+, though the aging maintenance status warrants monitoring.
