This tripped us up as well. MyPy suggested we pass a string, but the acceptable type depends on the algorithm, as algorith.prepare_key is called.

This appears to have been discussed in #605, #602 and the type annotation might have been changed to Any. There is more related work happening in #843 and #845

Indeed this is a duplicate of #602. Some additional context is available in #843, and the solution isn't trivial. pyjwt maintainers doesn't seem to be currently active on this project, so I'll get back on this when I'll get feedback on the #843 PR description

[auvipy]

is it fixed now?

is it fixed now?

I'll probably try to find some time to work on it, but as I said here #848 (comment), it might be tricky

But this is a duplicate, so I think it can be closed
