.. hazmat::
MultiBackend
============
.. currentmodule:: cryptography.hazmat.backends.multibackend
.. class:: MultiBackend(backends)
.. versionadded:: 0.2
This class allows you to combine multiple backends into a single backend
that offers the combined features of all of its constituents.
.. code-block:: pycon
>>> from cryptography.hazmat.backends.multibackend import MultiBackend
>>> from cryptography.hazmat.primitives import hashes
>>> backend1.hash_supported(hashes.SHA256())
False
>>> backend2.hash_supported(hashes.SHA256())
True
>>> multi_backend = MultiBackend([backend1, backend2])
>>> multi_backend.hash_supported(hashes.SHA256())
True
:param backends: A ``list`` of backend objects. Backends are checked for
feature support in the order they appear in this list.
