Using ^\s*(import crypt\b|from crypt\b) regex, I found the following PyPI top 5,000 projects using the removed crypt module.

Affected projects (8):

• Django (4.2)
• Twisted (22.10.0)
• ansible (7.4.0)
• ansible-core (2.14.4)
• htpasswd (2.3)
• passlib (1.7.4)
• pyftpdlib (1.5.7)
• pytest-testinfra (7.0.0)

Code:

Django-4.2/tests/auth_tests/test_hashers.py: import crypt
ansible-7.4.0/ansible_collections/community/general/plugins/modules/homectl.py: import crypt
ansible-7.4.0/ansible_collections/community/general/plugins/modules/udm_user.py: import crypt
Twisted-22.10.0/src/twisted/conch/test/test_checkers.py: import crypt
Twisted-22.10.0/src/twisted/cred/test/test_cred.py: from crypt import crypt as _crypt
Twisted-22.10.0/src/twisted/plugins/cred_unix.py: import crypt
ansible-core-2.14.4/lib/ansible/utils/encrypt.py: import crypt
passlib-1.7.4/passlib/tests/utils.py: from crypt import crypt
passlib-1.7.4/passlib/utils/__init__.py: from crypt import crypt as _crypt
pyftpdlib-1.5.7/pyftpdlib/authorizers.py: import crypt
pytest-testinfra-7.0.0/test/test_modules.py: import crypt
htpasswd-2.3/htpasswd/basic.py: from crypt import crypt

passlib (1.7.4)

It's interesting that the proposed replacement for the removed crypt module actually uses crypt internally (in /passlib/utils/__init__.py) :-)

Are these bits still needed?

Lib/ctypes/util.py
366:            print(f"crypt\t:: {find_library('crypt')}")
367:            print(f"crypt\t:: {cdll.LoadLibrary(find_library('crypt'))}")
373:            print(find_library("crypt"))

IMO we should keep it. I saw this test in ctypes. I don't see any direct relationship with the Python crypt module. It's just a test to load a dynamic library which is commonly available on Unix.
