It is supported. Make sure you have cryptography installed.

https://pyjwt.readthedocs.io/en/stable/installation.html#cryptographic-dependencies-optional

If crypto is not installed, RS256 will not be in your default algorithms list: https://github.com/jpadilla/pyjwt/blob/5ecbafc366ebc4940ce4eac81350bc41887a4433/jwt/algorithms.py#L79-L104

Also your installation may be older as line 272 in api_jws.py is not the raise InvalidAlgorithmError...: https://github.com/jpadilla/pyjwt/blob/master/jwt/api_jws.py#L272

I'm still getting this issue:

Traceback (most recent call last):

    return self._algorithms[alg_name]
KeyError: 'RS256'

The above exception was the direct cause of the following exception:

For those who will have this problem, try to install cryptography package. I have this problem when I migrating to poetry and I won't knew all deps my project has.
