I have a doubt regarding jwt plugin . Will this plugin creates jwt tokens or only authenticates the jwt token created by a authentication micro service

Just authenticates, although their source code library has methods around how to produce a JWT token, our plugin uses it to produce and send JWT tokens to a backend api:
