I did not find any big issue, but did have a lot of suggestions, therefore marking the review as "Request changes". Most of them should be quite easy to solve though.

Once that is done, I can do a quick pass again and approve.

Some nits from my side, but overall I think it looks good. I agree with the general comments about test organization from Reynaldo.

The only blockers I see are:

1. Some docstrings are a bit confusing right now.
2. The tests that use OsRng should be made deterministic.

Thank you for the updates! Left a couple of nits
