-    contains a complete set of cryptographic primitives as well as a
-    significantly better and more powerful X509 API. If necessary you can
-    convert to and from cryptography objects using the ``to_cryptography``
-    and ``from_cryptography`` methods on ``X509``, ``X509Req``, ``CRL``,
-    and ``PKey``.
