From the moment a certificate is revoked, both the original certificate and any copies that may have been made will cease to be valid and may no longer be used even if the certificate's expiration date has not yet arrived.


If you want to permanently cancel your idCAT Certificate or, as its holder, you suspect or are certain that a third party has access to your certificate (you have lost it or it has been stolen), you must revoke it. Revocation implies the total deactivation and permanent cancellation of the certificate and any copy of it.
