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• Your personal data, included in the certificate, is no longer valid/applicable.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: 

ra@rwth-aachen.de

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:

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.

By clicking the button Revoke certificate, your revocation request is sent to the registrations autorities and must be approved.

After approval by the registration authorities, you will receive an e-mail confirming the revocation of your certificate.
