Backends
========
Getting a backend
-----------------
.. currentmodule:: cryptography.hazmat.backends
``cryptography`` was originally designed to support multiple backends, but
this design has been deprecated.
You can get the default backend by calling :func:`~default_backend`.
.. function:: default_backend()
:returns: An object that provides at least
:class:`~interfaces.CipherBackend`, :class:`~interfaces.HashBackend`, and
:class:`~interfaces.HMACBackend`.
Individual backends
