should the best course of action in this scenario to use java libraries like this: https://bitbucket.org/b_c/jose4j/wiki/Home or this: https://github.com/jwtk/jjwt?

When you

compile "io.ktor:ktor-auth-jwt:$ktor_version"

, you also get

com.auth0:java-jwt

. Then you just use

JWT.create()

thankou @avolkmann 👍
