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 as our CA.

A valid TLS certificate is required to ensure secure server communications.

InCommon SSL (SHA-2)

By default, we issue Organization Validation (OV) TLS/SSL Certificates which are a step up from Domain Validation (DV) Certificates because they prove that you have a relationship with the university. Like DV certificates, OV certificates show trust indicators in browsers like the padlock icon and the string https:// before the website domain.

InCommon Multi-Domain SSL (SHA-2)

Also commonly referred to as SAN certificates, multi-domain TLS/SSL allow a single certificate to secure multiple domains, including sub-domains of a single main domain name or entirely different domain names. One of these can secure up to 250 unique domains with a single solution. They provide a convenient option for units that own a lot of domains and are looking for a simplified way to secure them through a single solution rather than purchasing an individual certificate for each.


  • InCommon SSL (SHA-2) & InCommon Multi-Domain SSL (SHA-2) SAN certificates are available
  • The maximum certificate duration is 398 days
  • The Sectigo Network Agent is available for the automation of certificate creation, installation, and renewal


  • TLS server certificates are available for servers with a UIC.EDU FQDN
  • Certificate Signing Request (CSR) that's created from a 2048-bit or larger key pair
  • Revocations are not automatically performed when a certificate renewal is requested


TLS server certificates can only be issued within the UIC.EDU domain. Certificates requests are usually processed within 2 business days.

Certificates can be renewed any time before the expiration date and for convenience certificate expiration warnings messages are sent to the registered requesters 28, 7, and 1 day(s) prior to expiration. Emergency renewals cannot be guaranteed for certificates that have expired.
