If you already possess a certificate of the certification authority for Fraunhofer contacts, you can revoke your certificate with the help of this webpage. A revocation is for example necessary if

• your e-mail address has or will change,
• you do not want to use the certificate for secure communication within a Fraunhofer-related context anymore,
• you do not accept and/or fulfil the guidelines of the PKI for Fraunhofer contacts any longer, or
• an abuse or a compromise of the private key is suspected or has occured.

In order to avoid that a third party revokes your certificate, the revocation is organised in a two-stage process. Firstly the certificate which is to be revoked must be identified. Therefore please provide us below with the e-mail address named within the corresponding certificate. An e-mail will be dispatched to this address containing a special link - similar to the process for obtaining a certificate. With the help of this link you are then able to revoke your certificate finally.

In case that several certificates are issued for the indicated e-mail address, the revocation e-mail contains all attached certificates and you have the possibility to select individually the certicates which shall be revoked.
