| Getting a backend |
| ----------------- |
| |
| .. currentmodule:: cryptography.hazmat.backends |
| |
| ``cryptography`` aims to support multiple backends to ensure it can provide |
| the widest number of supported cryptographic algorithms as well as supporting |
| platform specific implementations. |
| |
| You can get the default backend by calling :func:`~default_backend`. |
| |
| The default backend will change over time as we implement new backends and |
| the libraries we use in those backends changes. |
| |
| |
| .. function:: default_backend() |
| |
| :returns: An object that provides at least |
| :class:`~interfaces.CipherBackend`, :class:`~interfaces.HashBackend`, and |
| :class:`~interfaces.HMACBackend`. |
