**Note:** The Python Cryptographic Authority **strongly suggests** the use of `pyca/cryptography`_
where possible. If you are using pyOpenSSL for anything other than making a TLS connection
**you should move to cryptography and drop your pyOpenSSL dependency**.

High-level wrapper around a subset of the OpenSSL library. Includes

* ``SSL.Connection`` objects, wrapping the methods of Python's portable sockets
* Callbacks written in Python
* Extensive error-handling mechanism, mirroring OpenSSL's error codes

... and much more.

You can find more information in the documentation_.
Development takes place on GitHub_.

## AI interpretation — verify before relying

pyOpenSSL wraps OpenSSL's SSL/TLS functionality for Python, providing high-level connection objects and certificate handling. The maintainers recommend using cryptography directly for non-TLS use cases.

Verdict: Mature, actively maintained SSL/TLS wrapper with low install friction and no known vulnerabilities. However, the maintainers explicitly recommend migrating to cryptography for non-TLS use cases, so evaluate whether this package is the right fit for your specific needs before adopting it.
