Dear All  
I have Node-RED installed into an EC2 Virtual machine with Debian in AWS.

Following this guide, I'm able to let connect my ESP32 to AWS via MQTT.

In AWS IOT console Test, I see the data of the DHT22 sensor, trasmitted by ESP32 to AWS.

**So all is working good**

My problem is:  
**How configure AWS Node-Red MQTT broker, to read the data received from device connected to AWS with the "password authentication"** creaded with "AWS CloudFormation templates" instead of use the MQTT broker with "private certificates".  
In fact, I have no files .certificate.pem.crt or .private.pem.key pubblic.pem.key etc. to add to MQTT BROKER Node in Node-red AWS EC2!  
Moreover I dont' know if I have to install the "mosquitto" mqttt broker in Linux EC2.

Thanks in advance.
