Chariot uses certificates and TLS/SSL to secure Chariot HTTP and MQTT traffic. The process for obtaining SSL certificates to be used to secure HTTP and MQTT traffic to Chariot is the same whether using an external, /commercial Certificate Authority (CA) or your company's internal Certificate Authority (CA). Cirrus Link doesn't recommend any specific Certificate Authority (CA), but we do recommend using an external, well-known and non-self-signed certificates from a trusted Certificate Authority for issuing securing your SSL certificatesProduction assets.
