    <p>This node generates the magic key for the embedded LoRa module. It uses 128-bit AES encryption and requires a secret 8-digit key. Once the key has been uploaded to the LoRa module, you can safely delete this node from the Node-RED flow editor.</p>
    <p>Inject a string in <strong>msg.payload</strong> property:</p>
    <ul>
        <li>Use <strong>"enable"</strong> to activate AES encryption</li>
        <li>Use <strong>"disable"</strong> to deactivate AES encryption</li>
    </ul>
    <p>Inject the magic key using <strong>msg.key</strong> property:</p>
    <ul>
        <li>Provide a string with a maximum of 8 digits</li>
        <li>If the key is too long, it will output on <strong>Output 2</strong>: <strong>Error: Key is too long</strong></li>
        <li>If the key is too short, it will output on <strong>Output 2</strong>: <strong>Error: Key is too short</strong></li>
    </ul>
    <p>Output 1 will output the generated hex command for enable/disable.</p>
    <p>Output 2 will output the generated magic key hex or key length error message.</p>
