We are using a Linux server to send a message to an UNO over serial. The challenge is that the message must be encrypted. The UNO will be receiving the encrypted message. Making sure that the encryption generated by the server is compatible with the UNO. Would appreciate any suggestion as to how to accomplish this.
Does that mean you are actually getting the message correctly from the server, but now need to encrypt the message? OR is the message already encrypted and is being received and now you want your Arduino to decode the message? This assumes you know how the message is encrypted and how to decode it.
I am wondering where to start and if somebody has done this before.
@ [Paul_KD7HB] Thank you for responding!
Start with getting a message, any message, to be sent by the server and received correctly by the Arduino.
Presuming you can already send a message between the server and the Arduino, you will need to use an encryption function on the server to encrypt it, and the corresponding decryption function on the Arduino, to decrypt it.
Please describe what you have done so far, and where you are stuck. See the "How to get the best out of this forum" post for hints.
I am looking for a tutorial or some guidance to get started.
Do you know what message to send to the server asking it to send a message? If it is REALLY a server, it will not automatically serve a message.
@Paul_KD7HB Thank you, I will.
it is a Node.js application on the server side.
If you say so. What does that mean?
Looking at using the AES128 library for JavaScript and on Arduino.
