Is it possible to encrypt/decrypt the messages between the LoRa sender and receiver. In the examples the messages are open to everyone.

Hi.
You are right. In our examples, the messages are not encrypted because we haven’t found straightforward solutions and we didn’t want to complicate the examples.
I haven’t tried encryption, but there is a library to encrypt LoRa messages with the ESP32. I hope this is useful:

Alternatively, you can also use LoraWAN (the messages are encrypted):

I hope you found these resources useful.
