crypt module missing dependency _crypt in python 3.13

[lucas42]

The crypt module has a dependency an internal library _crypt, which isn't included here. Both were removed in python 3.13. Presumably _crypt wasn't copied here as it isn't a pure python module.

Not sure it's worth putting a lot of effort into fixing this. The official python docs point towards https://passlib.readthedocs.io/en/stable/ as a replacement for the crypt module.
