title: Decoding Keycloak JWT Token
body: <p>I'm trying to validate (and read roles from) a JWT Token. Sadly I can't use any adapter or auto configuration due to my overall application architecture.</p>
  <p>It's no problem to decode the token like any other JWT Token, but I wonder if there is a library from Keycloak to archive this goal. (For example Just Parse the token to something like a KeycloakJWTToken and verify it by grabbing the secret from Keycloak Server or so)</p>
  <p>Any easy-to-use client or so?</p>
