**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.
