Kong can verify its signature and time constraints before the request reaches the backend.</p> <p>This article separates the token structure, the cryptographic credential stored in Kong, and the Consumer representing the client. We then build a reproducible Kong Ingress Controller lab with an HS256-signed JWT and a <code>/jwt</code> route.</p> <div class="alert info"> <span><i data-feather="info"></i></span> <span><strong><p>This lab continues directly from <a href="https://www.javiercd.es/posts/kong/03-instalacion-kic/03-instalacion-kic/">Installing KIC</a>. It reuses the <code>kong</code> Gateway, the <code>echo</code> Service, and the <code>192.168.121.200</code> address assigned by MetalLB to <code>kong-gateway-proxy</code>.</p>
