Requesting Digital Server Certificates

**Please note that ALL Certificates issued from this service use a chained certificate hierarchy. To avoid any Intermediate CA Certificate browser errors, be sure you have installed all of the required certificates on your system. For more information, please visit our FAQ section.**

The Information Security and Policy Office (ISPO) are offering centrally funded SSL certificates to UI System Administrators through the InCommon Digital Certificate service.

How do I get a TLS for my iowa-domain system?

There are 2 ways with which to do this.

  1. Where possible Campus System Admins (ITS, HCIS etc.) should contact The Information Security and Policy Office or their Departmental Registration Authority Organization (DRAO – “certificate approver”) to get your unique departmental “Access Code”.  Follow the steps below using that DRAO-specific code in place of the enterprise code  listed  below.
    NOTE: Campus administrators with co-managed systems should work with their "Primary" contact in SST to facilitate with management of TLS if needed.
  2. UI departments that have no DRAO should utilize the Enterprise Account when filling out the certificate request form, using the assigned Enterprise Access Code: uiowa-1nC0m.
Department/College/Org. Access Code
Healthcare and Information Systems (UIHC included) R7927HCib-211
DIVMS C01c3n$e
Engineering Enginr!ng
College of Public Health rCoPh-7329i


How to fill out the online certificate request form

  1. Go to
  2. Select Certificate Enrollment
  3. Enter in the Access Code: uiowa-1nC0m and your university e-mail address; click the Check Access code button to proceed (non-university e-mail addresses will not work).

Make certain all fields on the form with the red asterisk are correctly filled out


  1. Choose the type of TLS you need (TLS descriptions and restrictions below)
  2. Fill in the Common Name (CN)
  3. Choose the appropriate server OS
  4. Select the validity period of the TLS
  5. Paste in your 2048-bit CSR – Note: the interface will not accept any key lengths less than 2048-bit.
  6. Enter  a pass-phrase (required to revoke the certificate)
  7. Add in additional comments you would like to associate the TLS with (these will not be included in the certificate).
  8. Select “Submit”

Once approved you should receive an e-mail with instructions on how to download and install the TLScertificate.

NOTE: While most requests are processed within 24 hours, we only guarantee a 72 hour turnaround time on requests. Therefore, it is imperative that you plan accordingly. Certificates will NOT be issued outside of normal business hours.

If you have questions or problems processing your request for a digital certificate using the steps described above, contact The Information Security and Policy Office or your DRAO to have them process the TLS request on your behalf.


Available Digital Certificate Options:

InCommon SSL

Single domain name certificate.

InCommon Multi-Domain

Secures up to 100 different domain names on a single certificate.

InCommon Wild Card SSL

Secures the domain and unlimited sub-domains of that domain.  These must be preapproved by the ISPO.

InCommon Unified Communications Certificate (UCC) Subject Alternate Name certificate. Must be reissued each time you add a new host/domain name.

Extended Validation (EV) SSL/TLS

Extended Validation certificates provide the highest levels of encryption, security and trust and immediately reassure web site visitors that it is safe to conduct online transactions by turning the address bar green on next generation browsers.

Client or S/MIME Certificate

Secure/Multipurpose Internet Mail Extensions (S/MIME) or Client certificates, used primarily to digitally sign or encrypt e-mail messages.


Extended Validation (EV) Certificates

EV Certificates are available from Comodo/Sectigo through the University's Digital Certificate Service. Due to the nature of the validation, the process for obtaining an EV certificate is significantly longer approximately two-four weeks; so please plan ahead.

Requesting EV Certificates

Follow the instructions above to get to the online certificate request form then fill out all of the fields, making sure you select "Comodo SGC EV certificate" in the drop down “Type” field, paste in the CSR and submit the form. ISPO will approve the CSR request and forward it to Comodo/Sectigo.

Make note of your order number when you submit the form, as you will need it to complete the second step in the EV Certificate request process. Once you get your order number download and complete the .pdf form by clicking this UI-Comodo EV Certificate Request Form link.

***The form is where you must include your order number from the initial web certificate request, in either the subject and body of the email or on your fax cover sheet.***

As this form has been pre-filled only complete the "Domain Name(s)", "Certificate Requester", "Signature" and "Date" sections.

For legal reasons, the pre-populated form fields must not be altered or your request will be denied.

Send the completed form to Comodo/Sectigo via email or fax.
Fax: 1-866-446-7704

For more information on EV Certificates, click the following InCommon Extended Validation Certificates page link.

Note: The instructions on this page will indicate that a submission of a Subscriber Agreement and Legal Opinion letter are required. These have already been submitted on behalf of The University of Iowa; discard those details. You need only submit the Comodo EV Certificate Request Form. Feel free to contact the Information Security and Policy Office if you have additional questions.
