-Deprecated Concrete Classes
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-These classes were deprecated in version 0.5 in favor of backend specific
-providers of the
-:class:`~cryptography.hazmat.primitives.interfaces.DSAParameters`,
-:class:`~cryptography.hazmat.primitives.interfaces.DSAPrivateKey`, and
-:class:`~cryptography.hazmat.primitives.interfaces.DSAPublicKey` interfaces.
-
-.. class:: DSAParameters(modulus, subgroup_order, generator)
-
-    .. versionadded:: 0.4
-
-    .. deprecated:: 0.5
-
-    DSA Parameters are required for generating a DSA private key.
-
-    You should use :meth:`~generate` to generate new parameters.
-
-    .. warning::
-        This method only checks a limited set of properties of its arguments.
-        Using DSA parameters that you do not trust or with incorrect arguments
-        may lead to insecure operation, crashes, and other undefined behavior.
-        We recommend that you only ever load parameters that were generated
-        with software you trust.
-
-
-    This class conforms to the
-    :class:`~cryptography.hazmat.primitives.interfaces.DSAParameters`
-    interface.

-
-    :raises ValueError: This is raised when the values of ``modulus``,
-                        ``subgroup_order``, or ``generator`` do
-                        not match the bounds specified in `FIPS 186-4`_.
-
-    .. classmethod:: generate(key_size, backend)
-
-        Generate a new ``DSAParameters`` instance using ``backend``.
-
-        :param int key_size: The length of the modulus in bits. It should be
-            either 1024, 2048 or 3072. For keys generated in 2014 this should
-            be `at least 2048`_ (See page 41).  Note that some applications
-            (such as SSH) have not yet gained support for larger key sizes
-            specified in FIPS 186-3 and are still restricted to only the
-            1024-bit keys specified in FIPS 186-2.
