| 11 | ``cryptography`` aims to support multiple backends to ensure it can provide |
| 12 | the widest number of supported cryptographic algorithms as well as supporting |
| 13 | platform specific implementations. |

| Alex Gaynor | 8f42fe4 | 2013-12-24 13:15:52 -0800 | [diff] [blame] | 15 | You can get the default backend by calling :func:`~default_backend`. |
| David Reid | d5d085e | 2013-11-25 09:45:52 -0800 | [diff] [blame] | 16 | |
| 17 | The default backend will change over time as we implement new backends and |
| 18 | the libraries we use in those backends changes. |

| 23 | :returns: An object that provides at least |
| 24 | :class:`~interfaces.CipherBackend`, :class:`~interfaces.HashBackend`, and |
| 25 | :class:`~interfaces.HMACBackend`. |
