I was attempting to look through hashlib to try and understand more about python's built-in hash functions. As part of this, I ran 'help(_hashlib)' which returns this text: 'MODULE REFERENCE
    https://docs.python.org/3.11/library/_hashlib.html'

This is an invalid link which has been an issue in all versions of the documentation I looked up.

As an aside, where would I find the source for _hashlib?

I'm closing this as a duplicate of bpo-40051, as it's basically another manifestation of that issue.

However, any module named with a leading underscore is a private module, and won't have documentation.

The source for _hashlib can be found in Modules/_hashopenssl.c.

superseder: Give proper link in help(idlelib/turtledemo/tkinter.sub/test_*/?)
