Creates a 2048-bit RSA key pair and issues an X.509 certificate using the issued public key. You can also call CreateKeysAndCertificate over MQTT from a device, for more information, see Provisioning MQTT API.

Note This is the only time IoT issues the private key for this certificate, so it is important to keep it in a secure location.

Requires permission to access the CreateKeysAndCertificate action.
