When creating a "Thing" in "IoT Core" AWS let me download 5 security related files:
- Device certificate: ???-certificate.pem.crt
- Public key file: ???-public.pem.key
- Private key file: ???-private.pem.key
- Amazon trust services endpoint, RSA 2048 bit key: Amazon Root CA 1: AmazonRootCA1.pem
- Amazon trust services endpoint, ECC 256 bit key: Amazon Root CA 3: AmazonRootCA3.pem
So which one I should upload to device when it is asking "Upload custom SSL certifiate"? Or should I create some bundle I have read about?
I'm able to find this from Shelly documentation but in my mind that doesn't tell the answer: https://shelly-api-docs.shelly.cloud/gen2/ComponentsAndServices/Mqtt
