``cryptography`` is a package which provides cryptographic recipes and

primitives to Python developers. Our goal is for it to be your "cryptographic

standard library". It supports Python 3.7+ and PyPy3 7.3.11+.

``cryptography`` includes both high level recipes and low level interfaces to

common cryptographic algorithms such as symmetric ciphers, message digests, and

key derivation functions. For example, to encrypt something with

``cryptography``'s high level symmetric encryption recipe:

.. code-block:: pycon

    >>> from cryptography.fernet import Fernet

    >>> # Put this somewhere safe!

    >>> key = Fernet.generate_key()

    >>> f = Fernet(key)

    >>> token = f.encrypt(b"A really secret message. Not for prying eyes.")

    >>> token

    b'...'

    >>> f.decrypt(token)

    b'A really secret message. Not for prying eyes.'

You can find more information in the `documentation`_.

You can install ``cryptography`` with:

.. code-block:: console

    $ pip install cryptography

For full details see `the installation documentation`_.

Discussion

~~~~~~~~~~

If you run into bugs, you can file them in our `issue tracker`_.

We maintain a `cryptography-dev`_ mailing list for development discussion.

You can also join ``#pyca`` on ``irc.libera.chat`` to ask questions or get

involved.
