pyOpenSSL – A Python wrapper around the OpenSSL library

Stable Docs Build status Test coverage

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.

Release Information

16.0.0 (2016-03-19)

This is the first release under full stewardship of PyCA. We have made many changes to make local development more pleasing. The test suite now passes both on Linux and OS X with OpenSSL 0.9.8, 1.0.1, and 1.0.2. It has been moved to py.test, all CI test runs are part of tox and the source code has been made fully flake8 compliant.

We hope to have lowered the barrier for contributions significantly but are open to hear about any remaining frustrations.

Backward-incompatible changes:

  • Python 3.2 support has been dropped. It never had significant real world usage and has been dropped by our main dependency cryptography. Affected users should upgrade to Python 3.3 or later.

Deprecations:

  • The support for EGD has been removed. The only affected function OpenSSL.rand.egd() now uses os.urandom() to seed the internal PRNG instead. Please see pyca/cryptography#1636 for more background information on this decision. In accordance with our backward compatibility policy OpenSSL.rand.egd() will be removed no sooner than a year from the release of 16.0.0.

    Please note that you should use urandom for all your secure random number needs.

  • Python 2.6 support has been deprecated. Our main dependency cryptography deprecated 2.6 in version 0.9 (2015-05-14) with no time table for actually dropping it. pyOpenSSL will drop Python 2.6 support once cryptography does.

Changes:

  • Fixed OpenSSL.SSL.Context.set_session_id, OpenSSL.SSL.Connection.renegotiate, OpenSSL.SSL.Connection.renegotiate_pending, and OpenSSL.SSL.Context.load_client_ca. They were lacking an implementation since 0.14. #422

  • Fixed segmentation fault when using keys larger than 4096-bit to sign data. #428

  • Fixed AttributeError when OpenSSL.SSL.Connection.get_app_data() was called before setting any app data. #304

  • Added OpenSSL.crypto.dump_publickey() to dump OpenSSL.crypto.PKey objects that represent public keys, and OpenSSL.crypto.load_publickey() to load such objects from serialized representations. #382

  • Added OpenSSL.crypto.dump_crl() to dump a certificate revocation list out to a string buffer. #368

  • Added OpenSSL.SSL.Connection.get_state_string() using the OpenSSL binding state_string_long. #358

  • Added support for the socket.MSG_PEEK flag to OpenSSL.SSL.Connection.recv() and OpenSSL.SSL.Connection.recv_into(). #294

  • Added OpenSSL.SSL.Connection.get_protocol_version() and OpenSSL.SSL.Connection.get_protocol_version_name(). #244

  • Switched to utf8string mask by default. OpenSSL formerly defaulted to a T61String if there were UTF-8 characters present. This was changed to default to UTF8String in the config around 2005, but the actual code didn’t change it until late last year. This will default us to the setting that actually works. To revert this you can call OpenSSL.crypto._lib.ASN1_STRING_set_default_mask_asc(b"default"). #234
