Welcome to the Jisc Certificate Service group.

For an update on the NEW Jisc certificate service please follow the below link.

The New Jisc Certiface Service 

The service offers a number of different X509 SSL certificates, including Extended Validation certificates that give users the highest possible assurance, as well as S/MIME email certificates for digitally signing emails. Jisc has an agreement with the Certificate Authority, QuoVadis who is the provider of the certificates.

The service has been running since 2006 and has issued many thousands of certificates to organisations in UK research and education.

This is a Community group where users can obtain relevant information, receive service updates and provide feedback.

An issue regarding the use of the OCSP Signing EKU in issuing CAs is affecting hundreds of CAs in the industry including QuoVadis (see more at https://www.digicert.com/blog/working-with-delegated-ocsp-responders-and-eku-chaining/).

We will communicate with each institution separately and provide a list of the affected certificates shortly with instruction on replacements that will be required. We will add the necessary credits to the account to issue replacements

Please see further update from QuoVadis on the OU field Issue:

Retiring the OU field for public TLS/SSL 

QuoVadis will turn off the Organizational Unit (OU) field for all new public TLS/SSL certificates starting on August 31, 2020 at 00:59. This will affect new, reissued, and renewed certificates. Existing certificates with OUs are not affected (and do not require revocation or replacement).

As a user of the certificate service, I wanted to let you know that our supplier is increasing the tariff prices on this service in addition to increasing administration costs. This means that as of 1 October 2019, the cost of credits will change as per the table below.

Any credits bought between now and 1st of October will be charged at the current price and remain valid for two years.

Jisc’s Certificate Service is due for re-procurement in 2021 and as part of this process we want to get your views.

We are inviting those who use the service to take part in a workshop on Tuesday 24th September at Jisc’s offices in London. During the day we will be asking for your feedback on the existing service and provide you with the opportunity to discuss any additional functionality that would enhance the service.

The workshop will start at 10:30 and finish at 15:00 – lunch will be provided.
