pyOpenSSL 24.2.1

Description:

pyOpenSSL 24.2.1

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.

Discussion
If you run into bugs, you can file them in our issue tracker.
We maintain a cryptography-dev mailing list for both user and development discussions.
You can also join #pyca on irc.libera.chat to ask questions or get involved.
