Welcome to the Jisc Certificate Service group.

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.

All certificates issued are SHA-256.
