+
+`RSA`_ is a `public-key`_ algorithm for encrypting and signing messages.
+
+.. class:: RSAPrivateKey(p, q, private_exponent, dmp1, dmq1, iqmp, public_exponent, modulus)
+
+    .. versionadded:: 0.2
+
+    An RSA private key is required for decryption and signing of messages.
+
+    You should use :meth:`~generate` to generate new keys.
+
+    .. warning::
+        This method only checks a limited set of properties of its arguments.
+        Using an RSA private key that you do not trust or with incorrect
+        parameters may lead to insecure operation, crashes, and other undefined
+        behavior. We recommend that you only ever load private keys that were
+        generated with software you trust.
+
+
+    This class conforms to the
+    :class:`~cryptography.hazmat.primitives.interfaces.RSAPrivateKey`
+    interface.
+
+    :raises TypeError: This is raised when the arguments are not all integers.
+
+    :raises ValueError: This is raised when the values of ``p``, ``q``,
+                        ``private_exponent``, ``public_exponent``, or
+                        ``modulus`` do not match the bounds specified in
+                        :rfc:`3447`.
+
+    .. classmethod:: generate(public_exponent, key_size, backend)
+
+        Generate a new ``RSAPrivateKey`` instance using ``backend``.
+
+        :param int public_exponent: The public exponent of the new key.
+            Usually one of the small Fermat primes 3, 5, 17, 257, 65537. If in
+            doubt you should `use 65537`_.
+        :param int key_size: The length of the modulus in bits. For keys
+            generated in 2014 this should be `at least 2048`_. (See page 41.)
+            Must be at least 512. Some backends may have additional
+            limitations.
+        :param backend: A
+            :class:`~cryptography.hazmat.backends.interfaces.RSABackend`
+            provider.
+        :return: A new instance of ``RSAPrivateKey``.
+
+    .. method:: signer(padding, algorithm, backend)

+        .. versionadded:: 0.3
+
+        Sign data which can be verified later by others using the public key.

+
+    .. versionadded:: 0.2
+
+    An RSA public key is required for encryption and verification of messages.
+
+    Normally you do not need to directly construct public keys because you'll
+    be loading them from a file, generating them automatically or receiving
+    them from a 3rd party.
