How does the communication encryption work?
The communication is encrypted through AES and the method is as follows.
1. The server creates a random session key.
2. The sever encrypts the randomly created session key with a fixed key and sends it to the device.
3. The device decrypts the encrypted session key with a fixed key.
4. Then the communication is encrypted through the session key.
