Project description

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.

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.

Release Information

17.5.0 (2017-11-30)

Backward-incompatible changes:

  • The minimum cryptography version is now 2.1.4.

Deprecations:

none

Changes:

  • Fixed a potential use-after-free in the verify callback and resolved a memory leak when loading PKCS12 files with cacerts. #723

  • Added Connection.export_keying_material for RFC 5705 compatible export of keying material. #725

17.4.0 (2017-11-21)

Backward-incompatible changes:

none

Deprecations:

none

Changes:

  • Re-added a subset of the OpenSSL.rand module. This subset allows conscientious users to reseed the OpenSSL CSPRNG after fork. #708

  • Corrected a use-after-free when reusing an issuer or subject from an X509 object after the underlying object has been mutated. #709

17.3.0 (2017-09-14)

Backward-incompatible changes:

  • Dropped support for Python 3.3. #677

  • Removed the deprecated OpenSSL.rand module. This is being done ahead of our normal deprecation schedule due to its lack of use and the fact that it was becoming a maintenance burden. os.urandom() should be used instead. #675

Deprecations:

  • Deprecated OpenSSL.tsafe. #673

Changes:

  • Fixed a memory leak in OpenSSL.crypto.CRL. #690

  • Fixed a memory leak when verifying certificates with OpenSSL.crypto.X509StoreContext. #691
