.. method:: register_cipher_adapter(cipher_cls, mode_cls, adapter)
Register an adapter which can be used to create a backend specific
object from instances of the
:class:`~cryptography.hazmat.primitives.interfaces.CipherAlgorithm` and
the :class:`~cryptography.hazmat.primitives.interfaces.Mode` primitives.
:param cipher_cls: A class whose instances provide
:class:`~cryptography.hazmat.primitives.interfaces.CipherAlgorithm`
:param mode_cls: A class whose instances provide:
:class:`~cryptography.hazmat.primitives.interfaces.Mode`
:param adapter: A ``function`` that takes 3 arguments, ``backend`` (a
:class:`CipherBackend` provider), ``cipher`` (a
:class:`~cryptography.hazmat.primitives.interfaces.CipherAlgorithm`
provider ), and ``mode`` (a
:class:`~cryptography.hazmat.primitives.interfaces.Mode` provider).
It returns a backend specific object which may be used to construct
a :class:`~cryptogrpahy.hazmat.primitives.interfaces.CipherContext`.
