AWS MQTT integration: question about security certificates and key files

    Hi,

    I'm connecting ShellyPlusPlugS to AWS. While creating "Thing" in "IoT Core" AWS let me download 5 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

    Which file should I upload to Shelly plug?
