Describe how to renew an X.509 certificate from the InCommon CA via the UW Certificate Services website.

As part of the SHA-1 to SHA-2 migration (see Transition to InCommon SSL Certificates Signed with SHA-2), we've disabled renewals for InCommon SHA-1 certificates. At this point, renewal of a SHA-1 certificate would result in another SHA-1 certificate with a limited lifespan. There is no way to renew a SHA-1 certificate and get a SHA-2 certificate. As your InCommon SHA-1 certificate approaches its expiration date, you will need to request a new InCommon certificate. New certificates will be available with 1, 2, or 3 year lifespans and they will be signed with SHA-2. The renew option is available for InCommon SHA-2 certificates. 


  • You already have an InCommon certificate
  • The certificate has not yet expired or has expired no more than 30 days ago


  1. Browse to the UW Certificate Services website (authentication required):
  2. Select the certificate you want to renew from your list of favorites or locate it by using the Search box
  3. In the right-hand panel of certificate details, click the "renew this certificate" link
  4. Wait for the certificate to be signed and issued by the InCommon CA (turn-around time is 1-3 days)
  5. UW Certificate Services will check the status of your request and notify you via email when your InCommon certificate has been issued (see example below)
  6. Follow the instructions for downloading your certificate in Obtain a Certificate from the InCommon CA, beginning with step 14 in that document
  7. That's it! If it takes longer than 72 hours for your certificate to renew, or you encounter another problem, please let us know at
