DOD Root Certificates

Download DOD Root Certificates

Secure websites (HTTPS) use digital certificates to establish secure connections via Public Key Infrastructure (PKI). In order for a web browser to properly authenticate the identity of a secure website, it must know to communicate with the Certificate Authority (CA) that issues the site its digital certificate. Most web browsers already have commercial CA certificates associated. However, military hosting utilizes its own CA's.

As DCPAS is subject to the rules set by military hosting, you may need to manually install the DoD CA certificates on your personal or non-DoD computer in order to access our secure website. DoD-issued computers generally have these certificates and are up-to-date.
