LoRa encryption

Hello everyone!

I have two Heltec LoRa boards (V2 and V3). I would like to use one of them as a gate and the other as a door sensor. I successfully installed OpenMQTTGateway on the V2 board and was able to receive LoRa messages from the second node (V3 board). However, I noticed that messages are sent in plain text.

  1. Can the encryption be used when sending LoRa messages?
  2. Is the OpenMQTTGateway support encryption and if yes, then how can I configure it?

Thanks in advance,
