:mod:`!crypt` --- Function to check Unix passwords
==================================================

.. module:: crypt
   :synopsis: Removed in 3.13.
   :deprecated:

.. deprecated-removed:: 3.11 3.13

This module is no longer part of the Python standard library.
It was :ref:`removed in Python 3.13 <whatsnew313-pep594>` after
being deprecated in Python 3.11.  The removal was decided in :pep:`594`.

Applications can use the :mod:`hashlib` module from the standard library.
Other possible replacements are third-party libraries from PyPI:
:pypi:`legacycrypt`, :pypi:`bcrypt`, :pypi:`argon2-cffi`, or :pypi:`passlib`.
These are not supported or maintained by the Python core team.

The last version of Python that provided the :mod:`!crypt` module was
`Python 3.12 <https://docs.python.org/3.12/library/crypt.html>`_.
