public class JwtUtils {

    public static boolean verifyToken(String token, RSAPublicKey publicKey) {

            Claims claims = Jwts.parserBuilder()
                    .setSigningKey(publicKey)

                    .getBody();

            // Additional verification logic can be added here if needed

            // Check expiration
            Date expirationDate = claims.getExpiration();
            Date now = new Date();
            return !expirationDate.before(now); // Token is not expired
        } catch (Exception e) {
            e.printStackTrace();
            return false; // Token verification failed
        }
    }
