You can find more information on the website of the DFN-PKI.
University members - with the exception of students - can use the DFN-PKI to receive digital user certificates according to the X.509 standard, which are suitable for signing and encrypting files / documents and e-mails once they have been verified.
When applying for a user certificate, a key pair is generated on your PC under your user ID and in the web browser you use, which is then signed by the DFN-PKI.
Please apply for your user certificate on the DFN-PKI website on the Certificates / User Certificate card.
IMPORTANT: Do not do this in a public pool room.
Follow the instructions on the website. At the end of the application, you will be asked to print out the certificate application.
Print the application on a (!) double-sided (!) printed sheet. Please bring this certificate application, signed by hand, with a valid, official identification document to the University Computing Center.
After the test, you will receive an email from the DFN-PKI describing the further procedure. Please follow the instructions in the email here.
IMPORTANT: Carry out this process on the same PC, under the same user ID and in the same web browser that you used when applying for the user certificate.
