Now that is sorted out but some mypy issues remain. This is not something that I worked on but I can have a look at fixing them if you want...

The last commit is an important workaround to a Python 3.9.2 bug that prevents loading zxcvbn. While the problematic import introduced in #57 is technically correct and works on more...

Development is moved to main branch to avoid pushing more commits on this PR (based on master of our fork). We just released zxcvbn-covert 0.5.1 with everything on this PR...

@dwolfhub Cool. Do you wish for the typing fixes to be pushed on this PR as well, avoiding that test failure? Also I (faintly) recall seeing some Python 3.8 feature...

That should do it for the tests. I did not sync version numbers yet.

> You could also add the official `typing_extensions` as a conditional dependency for older python versions Would you wish to provide a patch for that? I don't even have anything...

Should also accept 32 byte plain keys. This 64-byte combined key format of libsodium is quite annoying, and too often I end up doing hacks like `sk + bytes(32)` to...

Both of those only appear to cover the Elligator 2 itself. Namely, they appear to miss the injection of (possibly randomised) sign and two random padding bits, and more importantly...

Testing for subgroup: unhash the Elligator 2 to get the public point, or just skip the Elligator encode/decode cycle. Scalarmult the public key by ```python q = 2**252 + 27742317777372353535851937790883648493...
