DigiCert Extends ClientAuth EKU Sunset Date to March 2027

DigiCert has announced an extended timeline for removing the Client Authentication (clientAuth) Extended Key Usage (EKU) from its public SSL/TLS certificates. The new deadline is March 1, 2027.

How it works?

Problem. Loss of clients due to distrust of your software as your operating system notifies users about unknown soft developer.

Solution. A signature for your code by using Code Signing certificate, which identifies a software developer and guarantees code integrity.

Result. More downloads of your code and consequent increase in sales and enhanced trust from client’s side.
