Certificate Services Support

Please note although the “Entrust Root Certification Authority – G2” is still listed on Microsoft’s cross-certificate-list, Entrust does not issue certificates which support kernel-mode signing.
Entrust provides attestation signing[3], which requires the use of an Entrust EV Codesigning Certificate in order to submit the driver to Microsofts Partner Center (also known as Hardware Dev Center Dashboard).
