Frequently asked questions
==========================
How does ``cryptography`` compare to NaCl (Networking and Cryptography Library)?
--------------------------------------------------------------------------------
While ``cryptography`` and `NaCl`_ both share the goal of making cryptography
easier, and safer, to use for developers, ``cryptography`` is designed to be a
general purpose library, interoperable with existing systems, while NaCl
features a collection of hand selected algorithms.
``cryptography``'s :ref:`recipes <cryptography-layout>` layer has similar goals
to NaCl.
If you prefer NaCl's design, we highly recommend `PyNaCl`_.
When I try to use ``cryptography`` on Windows I get a ``cffi.ffiplatform.VerificationError``
--------------------------------------------------------------------------------------------
This error looks something like:
.. code-block:: console
cffi.ffiplatform.VerificationError: importing '<some_path>.pyd': DLL load failed:
It typically occurs on Windows when the user has not installed OpenSSL. Download
a `pre-compiled binary`_ to resolve this issue.
