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 3.6+ as well as
|
|
PyPy 3.

Installation
|
|
============
|
|
|
|
Binary wheel install
|
|
--------------------
|
|
|
|
PyNaCl ships as a binary wheel on macOS, 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
|
|
|
|
Faster wheel build
|
|
------------------
|
|
|
|
You can define the environment variable ``LIBSODIUM_MAKE_ARGS`` to pass arguments to ``make``
|
|
and enable `parallelization`_:
|
|
|
|
.. code-block:: console
|
|
|
|
$ LIBSODIUM_MAKE_ARGS=-j4 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.
|
|
|
|
.. _parallelization: https://www.gnu.org/software/make/manual/html_node/Parallel.html
|
|
|
|
.. _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
|
|
=========
|
|
|
|
1.5.0 (2022-01-07)
|
|
------------------
|
|
|
|
* **BACKWARDS INCOMPATIBLE:** Removed support for Python 2.7 and Python 3.5.
|
|
* **BACKWARDS INCOMPATIBLE:** We no longer distribute ``manylinux1``
|
|
wheels.
|
|
* Added ``manylinux2014``, ``manylinux_2_24``, ``musllinux``, and macOS
|
|
``universal2`` wheels (the latter supports macOS ``arm64``).
|
|
* Update ``libsodium`` to 1.0.18-stable (July 25, 2021 release).
|
|
* Add inline type hints.
|
|
|
|
1.4.0 (2020-05-25)
|
|
------------------
|
|
|
|
* Update ``libsodium`` to 1.0.18.
|
|
* **BACKWARDS INCOMPATIBLE:** We no longer distribute 32-bit ``manylinux1``
|
|
wheels. Continuing to produce them was a maintenance burden.
|
|
* Added support for Python 3.8, and removed support for Python 3.4.
|
|
* Add low level bindings for extracting the seed and the public key
|
|
from crypto_sign_ed25519 secret key
|
|
* Add low level bindings for deterministic random generation.
|
|
* Add ``wheel`` and ``setuptools`` setup_requirements in ``setup.py`` (#485)
|
|
* Fix checks on very slow builders (#481, #495)
|
|
* Add low-level bindings to ed25519 arithmetic functions
|
|
* Update low-level blake2b state implementation
|
|
* Fix wrong short-input behavior of SealedBox.decrypt() (#517)
|
|
* Raise CryptPrefixError exception instead of InvalidkeyError when trying
|
|
to check a password against a verifier stored in a unknown format (#519)
|
|
* Add support for minimal builds of libsodium. Trying to call functions
|
|
not available in a minimal build will raise an UnavailableError
|
|
exception. To compile a minimal build of the bundled libsodium, set
|
|
the SODIUM_INSTALL_MINIMAL environment variable to any non-empty
|
|
string (e.g. ``SODIUM_INSTALL_MINIMAL=1``) for setup.
|
|
|
|
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
|
|
|
|

|
|
runtime environment.

|
|
------------------
|
|
|
|
* 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.

|
|
|
|
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.
