Dutch government to revoke #DigiNotar certificates on Wednesday

Share this article:

Certificates issued by DigiNotar are to be officially revoked this week by the Dutch government.

According to a statement by the Dutch government's public key infrastructure, PKIoverheid, DigiNotar's certificates will be revoked from this Wednesday (28 September) as the compromise contravenes its program requirements.

The move by the policy authority follows the decision by Dutch service provider OPTA to terminate the registration of DigiNotar and the company's bankruptcy last week.

The problems began for DigiNotar when its infrastructure was hacked by the ‘Comodo hacker', Sun Ich, in July, which left him able to sign SSL certificates for legitimate websites. The discovery a month later led to a number of browser providers, including Google, Mozilla, Microsoft and Apple, revoking access to DigiNotar-signed certificates.

The PKIoverheid Policy Authority said it was initially decided to use a controlled transition scenario where end-users were given the opportunity to switch to other suppliers or PKLoverheid certificates.

Adobe said that as a result of this action, new digital signatures created with certificates from these certificate families will no longer show as valid in Acrobat and Reader.

It said this is due to the fact that Acrobat and Reader will check if certificates associated with the signing credential are revoked at signing and upon opening the document.
