Python wrapper module around the OpenSSL library

Project description

Stable Docs Build status Test coverage

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 #cryptography-dev on Freenode to ask questions or get involved.
