This is a “Hazardous Materials” module. You should ONLY use it if you’re 100% absolutely sure that you know what you’re doing because this module is full of land mines, dragons, and dinosaurs with laser guns.


class cryptography.hazmat.backends.multibackend.MultiBackend(backends)

New in version 0.2.

This class allows you to combine multiple backends into a single backend that offers the combined features of all of its constituents.

>>> from cryptography.hazmat.backends.multibackend import MultiBackend
>>> from cryptography.hazmat.primitives import hashes
>>> backend1.hash_supported(hashes.SHA256())
>>> backend2.hash_supported(hashes.SHA256())
>>> multi_backend = MultiBackend([backend1, backend2])
>>> multi_backend.hash_supported(hashes.SHA256())
Parameters:backends – A list of backend objects. Backends are checked for feature support in the order they appear in this list.
