For connections in a private local area network this might not be a big issue, but if you connect to a broker on the internet or the gateway is connected to a public network there is a high security risk.</p> <p>To secure the connection, Transport Layer Security (TLS) can be used which is supported by most MQTT brokers.
Setting up and configuring TLS in the MQTT broker is a complex process and perhaps include creating a self-signed certificate.
The configuration of the broker is not covered here, you should look into the documentation of your broker.</p> <h3 id="prerequisites"><a href="#prerequisites" class="header-anchor">#</a> Prerequisites</h3> <p>The MQTT broker is configured for TLS and you have access to the CA certificate which was used to sign the MQTT broker certificate.
You are using ESP8266 or ESP32, for other boards TLS is not supported.</p> <h3 id="configure-secure-connection-in-the-gateway"><a href="#configure-secure-connection-in-the-gateway" class="header-anchor">#</a> Configure secure connection in the gateway</h3> <p>To enable the secure connection and use TLS set the <code>#define MQTT_DEFAULT_SECURE</code> to true.
Set <code>MQTT_SERVER</code> to the Common Name (CN) of the certificate of the broker.
This can be the hostname or the IP of the broker.</p> <p>The CA certificate should be in PEM ascii format.
If your CA certificate is not in the correct format or you don't know the format, use <code>openssl</code> to convert the certificate to the correct format.
In <code>User_config.h</code> replace the <code>...</code> with the content of your certificate which is between the <code>-----BEGIN CERTIFICATE-----</code> and <code>-----END CERTIFICATE-----</code> lines:</p> <div class="language-cpp line-numbers-mode"><pre class="language-cpp"><code><span class="token keyword">const</span> <span class="token keyword">char</span><span class="token operator">*</span> certificate CERT_ATTRIBUTE <span class="token operator">=</span> <span class="token raw-string string">R&quot;EOF(&quot;
