PyNaCl is a Python binding to `libsodium`_, which is a fork of the
`Networking and Cryptography library`_. These libraries have a stated goal of
improving usability, security and speed. It supports Python 2.7 and 3.4+ as
well as PyPy 2.6+.

.. _Networking and Cryptography library: https://nacl.cr.yp.to/

Features
--------

* Digital signatures
* Secret-key encryption
* Public-key encryption
* Hashing and message authentication
* Password based key derivation and password hashing

Installation
============

Binary wheel install
--------------------

PyNaCl ships as a binary wheel on OS X, Windows and Linux ``manylinux1`` [#many]_ ,
so all dependencies are included. Make sure you have an up-to-date pip
and run:

.. code-block:: console

    $ pip install pynacl

Linux source build
------------------

PyNaCl relies on `libsodium`_, a portable C library. A copy is bundled
with PyNaCl so to install you can run:

.. code-block:: console

    $ pip install pynacl

If you'd prefer to use the version of ``libsodium`` provided by your
distribution, you can disable the bundled copy during install by running:

.. code-block:: console

    $ SODIUM_INSTALL=system pip install pynacl

.. warning:: Usage of the legacy ``easy_install`` command provided by setuptools
   is generally discouraged, and is completely unsupported in PyNaCl's case.

.. _libsodium: https://github.com/jedisct1/libsodium

.. [#many] `manylinux1 wheels <https://www.python.org/dev/peps/pep-0513/>`_
    are built on a baseline linux environment based on Centos 5.11
    and should work on most x86 and x86_64 glibc based linux environments.

Changelog
=========

1.3.0 2018-09-26
----------------

* Added support for Python 3.7.
* Update ``libsodium`` to 1.0.16.
* Run and test all code examples in PyNaCl docs through sphinx's
  doctest builder.
* Add low-level bindings for chacha20-poly1305 AEAD constructions.
* Add low-level bindings for the chacha20-poly1305 secretstream constructions.
* Add low-level bindings for ed25519ph pre-hashed signing construction.
* Add low-level bindings for constant-time increment and addition
  on fixed-precision big integers represented as little-endian
  byte sequences.
* Add low-level bindings for the ISO/IEC 7816-4 compatible padding API.
* Add low-level bindings for libsodium's crypto_kx... key exchange
  construction.
* Set hypothesis deadline to None in tests/test_pwhash.py to avoid
  incorrect test failures on slower processor architectures.  GitHub
  issue #370

1.2.1 - 2017-12-04
------------------

* Update hypothesis minimum allowed version.
* Infrastructure: add proper configuration for readthedocs builder
  runtime environment.

1.2.0 - 2017-11-01
------------------

* Update ``libsodium`` to 1.0.15.
* Infrastructure: add jenkins support for automatic build of
  ``manylinux1`` binary wheels
* Added support for ``SealedBox`` construction.
* Added support for ``argon2i`` and ``argon2id`` password hashing constructs
  and restructured high-level password hashing implementation to expose
  the same interface for all hashers.
* Added support for 128 bit ``siphashx24`` variant of ``siphash24``.
* Added support for ``from_seed`` APIs for X25519 keypair generation.
* Dropped support for Python 3.3.

1.1.2 - 2017-03-31
------------------

* reorder link time library search path when using bundled
  libsodium

1.1.1 - 2017-03-15
------------------

* Fixed a circular import bug in ``nacl.utils``.

1.1.0 - 2017-03-14
------------------

* Dropped support for Python 2.6.
* Added ``shared_key()`` method on ``Box``.
* You can now pass ``None`` to ``nonce`` when encrypting with ``Box`` or
  ``SecretBox`` and it will automatically generate a random nonce.
* Added support for ``siphash24``.
* Added support for ``blake2b``.
* Added support for ``scrypt``.
* Update ``libsodium`` to 1.0.11.
* Default to the bundled ``libsodium`` when compiling.
* All raised exceptions are defined mixing-in
  ``nacl.exceptions.CryptoError``

1.0.1 - 2016-01-24
------------------

* Fix an issue with absolute paths that prevented the creation of wheels.

1.0 - 2016-01-23
----------------

* PyNaCl has been ported to use the new APIs available in cffi 1.0+.
  Due to this change we no longer support PyPy releases older than 2.6.
* Python 3.2 support has been dropped.
* Functions to convert between Ed25519 and Curve25519 keys have been added.

0.3.0 - 2015-03-04
------------------

* The low-level API (`nacl.c.*`) has been changed to match the
  upstream NaCl C/C++ conventions (as well as those of other NaCl bindings).
  The order of arguments and return values has changed significantly. To
  avoid silent failures, `nacl.c` has been removed, and replaced with
  `nacl.bindings` (with the new argument ordering). If you have code which
  calls these functions (e.g. `nacl.c.crypto_box_keypair()`), you must review
  the new docstrings and update your code/imports to match the new
  conventions.
