This shouldn't be public, if it needs to share data with the agent it should probably just be a private method on the agent.

The tests fail on Python 3, looks like you're trying to use a str as the header instead of a bytes.

@dreid How would I got about fixing the issue with the header being a str instead of bytes? I'm having trouble debugging that.

This self (and the agent argument in _build_digest_authentication_header are redundant.

Start by using byte strings (b"") everywhere internally.

@dreid I think I've got everything converted to using byte strings, now I'm getting 401 errors instead(I verified against a production server to confirm it's not just the tests that are failing) for python 3. Any idea what might be causing authentication to fail?

Sorry, I still have a few concerns about security here that I want to make sure are addressed in a comment or something.

I refactored the header builder based on the latest version in requests so it shouldn't be any worse than that version and appears to be unlikely to be a viable attack vector in practice here in general.

And we should really avoid adding new magic byte sequences without an accompanying Enum somewhere so that callers can type-check their invocations.

I changed algorithm to use an Enum.

I think we are (finally? after the better part of a decade? 😮‍💨) good to land this, modulo that one public name.

I think I'm going to accept a bit of a coverage hit here but I want to make sure I get an accurate sense of what the coverage hit is, so I'm going to attempt to re-run the tests on trunk (which involves a fake empty commit and a force push because you can't re-run workflow jobs after 30 days).
