SSL Certificates are offered for a one year period at no additional cost to University schools and administrative units.


How to Request Service

Members of the University must contact the DRAO for their area to request an SSL Certificate. Depending on the CSR process for participating schools and administrative units, server owners may be able to self-enroll for certificates.

Upon approval, applicants will receive an e-mail from InCommon which contains a link to the certificate collection form. Once the appropriate certificate ID is entered, the SSL certificate can be downloaded and installed for the domain. View the InCommon SSL Certificate Request Workflow.

Note: Approved requests are processed by InCommon within two to three business days.


Certificate Signing Requests

Each University school or administrative unit interested in using the InCommon SSL Certificate Service must delegate a maximum of two (one primary and one back-up) Departmental Registration Authority Officers (DRAOs) entrusted to authenticate applicants and review and approve Certificate Signing Requests (CSRs) through a secure Web interface.
