[Bug 1971580] Re: md4 hash does not work for Python in Jammy
I see. So, it is not a Ubuntu bug although it is not that obvious.
In short:
1) Some hashing algorithms with MD4 among them were disabled as obsoleted.
2) Cpython shows disabled hashing algorithms as available. Technically it is
correct because they are can be enabled and used. But it does not mean that
they can be used right away. Moreover, the exception you get is too generic and
provides no help whatsoever.
This workaround does the job:

Sebastien, thanks a lot!

The md4 algorithm isn't documented on https://docs.python.org/3/library/hashlib.html but the documentation state it also depends of what openssl provides or https://www.openssl.org/news/changelog.html indicates that openssl3 marked md4 as a legacy provider see also https://github.com/python/cpython/issues/91257 ** Bug watch added: github.com/python/cpython/issues #91257 https://github.com/python/cpython/issues/91257 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1971580 Title: md4 hash does not work for Python in Jammy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/python3.10/+bug/1971580/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
