SX1278 433 MHz RF E32-433T20D Module is a 5000-meter range wireless communication module that you can use as a receiver or transmitter. It is factory set to 433 MHz frequency. However, you can use the frequency you want in the 410-441 MHz range. Receiver and transmitter modules must have the same frequency. Data is not encrypted. It can be read by any receiver with the same frequency.
