`Argon2 <https://github.com/p-h-c/phc-winner-argon2>`_ won the `Password Hashing Competition <https://www.password-hashing.net/>`_ and *argon2-cffi* is the simplest way to use it in Python and PyPy:

.. code-block:: pycon

  >>> from argon2 import PasswordHasher
  >>> ph = PasswordHasher()
  >>> hash = ph.hash("s3kr3tp4ssw0rd")
  >>> hash  # doctest: +SKIP
  '$argon2id$v=19$m=102400,t=2,p=8$tSm+JOWigOgPZx/g44K5fQ$WDyus6py50bVFIPkjA28lQ'
  >>> ph.verify(hash, "s3kr3tp4ssw0rd")
  True
  >>> ph.check_needs_rehash(hash)
  False
  >>> ph.verify(hash, "t0t411ywr0ng")
  Traceback (most recent call last):
    ...
  argon2.exceptions.VerifyMismatchError: The password does not match the supplied hash


*argon2-cffi*'s documentation lives at `Read the Docs <https://argon2-cffi.readthedocs.io/>`_, the code on `GitHub <https://github.com/hynek/argon2-cffi>`_.
It’s rigorously tested on Python 3.5+, and PyPy3.

It implements *Argon2* version 1.3, as described in
`Argon2: the memory-hard function for password hashing and other applications <https://www.cryptolux.org/images/0/0d/Argon2.pdf>`_.

Release Information
===================

21.1.0 (2021-08-29)
-------------------

Vendoring Argon2 @ `62358ba <https://github.com/P-H-C/phc-winner-argon2/tree/62358ba2123abd17fccf2a108a301d4b52c01a7c>`_ (20190702)


Backward-incompatible changes:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Microsoft stopped providing the necessary SDKs to ship Python 2.7 wheels and currenly the downloads amount to 0.09%.
Therefore we have decided that Python 2.7 is not supported anymore.


Deprecations:
^^^^^^^^^^^^^

*none*


Changes:
^^^^^^^^

There are indeed no changes whatsoever to the code of *argon2-cffi*.
The *Argon2* project also hasn't tagged a new release since July 2019.
There also don't seem to be any important pending fixes.

This release is mainly about improving the way binary wheels are built (abi3 on all platforms).
