TLS Server Certificates

What Is It?

A server certificate is needed to enable Transport Layer Security (TLS) operation on a server (typically a web server), which verifies the server's identity to clients (typically web browsers), and enables encryption to secure communications from eavesdropping and maintain the integrity of the data transmitted. To avoid warning dialogs issued by web browsers, the certificate must be digitally signed by a trusted third party, a Certificate Authority (CA). UIC currently provisions certificates using Sectigo (formerly Comodo) as our CA.
