To encrypt data for LoRa by coding, you typically use a symmetric encryption algorithm like AES before sending the data. Here’s a general approach:

Most platforms (Arduino, STM32, Raspberry Pi, etc.) have AES libraries available. For example, on Arduino you can use [AESLib](https://github.com/DavyLandman/AESLib).
