Certificates can only be revoked by a Registration Authority. Please address your request to the issuing Registration Authority. To revoke a certificate the certificate holder must identify himself by the issuing Registration Authority.
In urgent cases out of business hours the LRA Swisscom (Switzerland) Ltd offers the possibility to request to revoke a certificate. Please search first the certificate to be revoked in the category Certificate inquiry and then click on the link "Request for revocation".
The SDCS revocation service is available during normal office hours (Monday - Friday) between 08:00 and 17:00 Berne local timezone. Outside of this timeframe (and public holidays) the revocation service is accessible but service is not guaranteed. A new CRL is published at least once per day between 03:00 and 05:00 UTC.
