JWT RS256 public key verification "jwt parse error: key is of invalid type"

[orzeszkownik]

Hello,
I have successfully configured mosquitto with JWT JS authorization it works well with HS256 tokens, but the problem is that "secret" have to be shared. So I generated tokens signed with private key and would like to verify it with public key. Is it possible, how to configure it? Now I get "jwt parse error: key is of invalid type" message in log.

Best,
