How do I authenticate your server's identity?

TLS: Our servers certificate is signed by one of the common trusted root CAs, Comodo, most OSes/browsers come with the Comodo cert built in. If you don't have a trust store you can download the AddTrust/Comodo root cert here: https://support.comodo.com/index.php?/Default/Knowledgebase/Article/View/979/108/domain-validation-sha-2
