InCommon Certificate Service


Indiana University has partnered with the InCommon Certificate Service to provide unlimited free SSL certificates to IU units. This new certificate service will replace the IU Certificate Authority (IUCA), and is available to all IU campuses.

Under the existing arrangement with InCommon, there is no charge for production certificates, and certificates can be used for all levels of service. The back-end vendor/Certificate Authority is Comodo, so the certs will work in all mainstream operating systems, web browsers, email clients, etc.

All certificates are available for a period of one, two, and three years. More information about the service can be found on the InCommon Cert Service page.

Note — Webserve users: please contact the IU Webmaster before taking any further action.

Extended Validation (EV) Certificates

EV Certificates are available from the Comodo Certificate Authority through this service. Due to the nature of the validation, the process for obtaining an EV certificate is significantly longer; please plan ahead.

To request an EV certificate:

  1. Select "EV certificate" via the standard certificate request process and submit the CSR
    • UISO will approve the CSR request and forward it to Comodo
    • Record your order number; you will need it.
  2. Download and complete the IU-Comodo EV Certificate Request Form
    • Complete only the Certificate Requester section, found on Page 2.
    • For legal reasons, the pre-populated form fields must not be altered, or your request will be denied. EV certificates are available to all campuses.
  3. Send the completed form to Comodo via email or fax.You must include your order number, either in the body of the email or a fax cover sheet.

For more information, visit the InCommon Extended Validation Certificates. Note: this page will indicate that the submission of a Subscriber Agreement and Legal Opinion letter are required. These have already been submitted on behalf of Indiana University; you may discard those details. You need only submit the Comodo EV Certificate Request Form.

A Note Regarding the "Organization" of the EV Certificates

Indiana University's EV SSL/TLS CertificatesFor legal reasons, the Organization Name found on the EV certificate (displayed in the "green" browser indicator) MUST be an organization's full legal name, as listed in official records. For IU (or any of IU's domains), this is: "Indiana University" (as displayed).

Unfortunately, certificate authorities are unable to issue EV certificates bearing any other name — including those of a department, office, or service. Attempts to falisify or modify the Certificate Request form will be denied and considered a breach of university policy.

For more information, visit the CA/Browser Forum.

Code-signing Certificates
