SSL Certificates

The University of Hawaii is partnered with the InCommon Certificate Service to provide unlimited free SSL certificates to UH units for web servers, code signing, and other services. Both single-domain and multi-domain certificates are available. 

All certificates are currently issued for a 1-year duration; multi-year certs are no longer available. In 2026, certificate lifespan will decrease to 200 days. In 2027, it will decrease to 100 days and in 2029, it will decrease to 47 days.
