Use of certificates

Certificate creation

On Friday, January 10, 2025 in the afternoon, the provider SECTIGO switched off the creation of new personal and server certificates for the DFN. The portal of the new provider HARICA for the UHH/DFN is now available for the creation of user and server certificates!

Note: The HARICA portal is still under construction, the functionality is being expanded in coordination with the DFN association.
The current status of the links and handouts can always be found on the RRZ website!

Personal S/MIME / User Certificates:

User certificates for signing (and possibly encrypting) emails can be requested as "self service" by logging in with the "B-Kennung" (via Shibboleth login). Please use the link to the HARICA web form and the registration option "Academic Login" and select "University of Hamburg (UHH)". A handout (currently only in German) with the details is maintained by the RRZ. Please read carefully before applying for a certificate! There are several "traps" in the portal menus!

After approval via email confirmation and release, t you can download the certificate (once!).

Note: Currently, group certificates (-> functional mailboxes) cannot be created!

SSL/Server certificates:

Server certificates can now also be requested as "self service" by logging in with the "B-Kennung" (via Shibboleth login). Prepared CSR data (certificate signing request) can be uploaded or generated by Harica.

Please use the link to the HARICA web form and the registration option "Academic Login" and select "University of Hamburg (UHH)". A handout (currently  only in German) with the details is maintained by the RRZ. Please read carefully before applying for a certificate! Here, too, there are several "traps" in the portal menus! The SSL certificates can currently only be applied for UHH subdomains!

The server certificate is not released automatically. Therefore, please send an email requesting release to  vl-pki-ts.inf@uni-hamburg.de(vl-pki-ts.inf"AT"uni-hamburg.de) (don't use the web form linked in the RRZ webpage, which is operated by RRZ admins!).

If you have any questions, please contact A. Heymann or R. Zierke at the IRZ directly.
