DFN-PKI Global Revoke user certificate

When does a user certificate need to be revoked?

  • Your personal data, included in the certificate, is no longer valid/applicable.
  • Your private RSA key or your password to the file containing it has been compromised.
  • You are no longer authorised to use the certificate.

You can request that the registration authority revokes your certificate. This is done on the DFN-PKI Webpage and you need to enter the revocation PIN, specified at certificate application.

If you have misplaced the PIN, contact the RWTH registration authority via mail:


Visit the DFN-PKI website and choose the option Revoke certificate in the menu on the top of the page or in the corresponding box:

Home page of the DFN-PKI portal

Enter the serial number, the certificate revocation PIN and the reason for revocation.

  • You can find the serial number in the e-mail you received when the certificate was issued. Alternatively, you can find the serial number in the certificate details of your operating system or e-mail application; 
  • You assigned the revocation PIN when you applied for the certificate.
  • If none of the revocation reasons from the list apply, select the option Unspecified.
