PKI / digital certificates

Certificates in general

Since 10 January 2025, no new certificates can be issued until further notice. 

The ZIH of the Technische Universität Dresden has been participating in the PKI (Public Key Infrastructure) of the German Research Network since July 2006 and issues certificates within this framework.
There are different types of certificates, which are selected according to their purpose.
