use Jose\Bundle\JoseFramework\Event\JWSVerificationFailureEvent;
use Jose\Bundle\JoseFramework\Event\JWSVerificationSuccessEvent;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;

class JwsSubscriber implements EventSubscriberInterface
{
    public static function getSubscribedEvents()
    {
        return [
            Events::JWS_VERIFICATION_SUCCESS => ['onJwsVerificationSuccess'],
            Events::JWS_VERIFICATION_FAILURE => ['onJwsVerificationFailure'],
