User certificate download

After receiving a notification of your certificate approval from DFN, you are not done yet! If you wonder, why to proceed at all, we would like to refer to the certificate basics.

Your user certificate is applicable only, if you also have your private key available. That key is contained in your application file (extension: json) and has to be collated with your certificate. The according workflow is provided again by the DFN and can be found


After uploading your application file you will receive a password protected container file (extension: p12) that contains your private key along with your certificate. You should select a rather strong password to protect your pirvate key appropriatly. To store the container, we recommend to use an external USB device that you connect to your computer only when needed. The next step is finally to use your certificate.
