User certificate application

The application form for a user certificate is hosted by the DFN at a web page you will find


During the application process you will receive two files: An application file (extension: json) and the actual application form (pdf). Keep the application file as it is required to pick up your certificate. Print and sign the application form and bring it to the IT- and Media Center along with a valid picture ID (no driving license).

The following staff members are pleased to check your form and perform a brief identy check (please make an appointment) :

  • Martin Sievers-Luboschik → Room 145
  • Jörg Maletzky → Room 141
  • Jörg Zerbe → Room 145

As soon as your application has been allowed, you may pick up and save your certificate. Details on this step can be found here.

Publication: Yes or No?

Publication: Yes or No?

During the application process you will be asked, if you would like to have your certificate publicly available. Answering Yes means, that anybody can search for your certificate at a DFN directory. That directory is not browsable, not scannable, and always requires the exact name or email address of the certificate's owner. With a found certificate, your may immediatly start an encrypted communication with the certificate's owner.

Choosing No means, that you need to exchange your certificates in an unencrypted communication prior to starting an encrypted communication.

You may withdraw the publication of your certificate at any time, but a later publication consent is not realisable.
