InstallRoot automates the install of the DoD Root certificates onto your Windows computer

 

If you want to access DoD websites from your Windows computer, you need this file.  You may need to reinstall them if the CAC enabled web site won't load, the website you are visiting is prompting you with the message there is a problem with the website's Security Certificate / site is not trusted, you have received a new CAC, or your DoD website worked up until recently and doesn't now.

 

 Apple computer users follow these instructions

 

Windows RT users follow these instructions

 

If you already have InstallRoot 4.1 or 5.0 installed, there is no need to install it again, go here to see the process of updating your certificates.

 

Download InstallRoot 5.0 from:
MilitaryCAC,     AKO,    or    DISA

Information:
A certificate is a digital document providing the identity of a Web site or individuals.  DoD Web sites use a certificate to identify themselves to their users and to enable secure connections.  If you are receiving a warning that a site is untrusted / insecure, you will need to install the "DoD Certificates."  In order to access sites enabled with a DoD PKI certificate without being prompted to accept the DoD Certificate chain at each log on [like Firefox and Safari do], people using Internet Explorer and Chrome should install the certificates.  These are separate from the personal certificates that are on your CAC, but they are related.

 

 

Root Certificates

 

How can you (or your web server) trust the identity of someone over the network?  An infrastructure of trusted third parties has been put in place to distribute trust between end-users.  This infrastructure verifies that we are who we say we are.  If we trust the DoD PKI infrastructure, then the infrastructure can vouch for us to trust others that have certificates issued from the DoD PKI.

.

The DoD PKI Infrastructure is comprised of two Root Certification Authorities and a number of Intermediate Authorities.  If all of the DoD root certificates are not installed on your computer, various applications will not be able to trust all DoD PKI certificates.
