If you're using Namoroka this site will not recognize it as Firefox and simply clicking on the link above will not get you into the site.  You can work around this problem (which affects some other websites too) by changing Namoroka's configuration a little.
 
#Open a new tab in Namoroka
 
#Type ''about:config'' in the address bar and press enter
 
#Type 'useragent' in the search box
 
#Double-click on the value where you see "Namoroka"
 
#Change "Namoroka" to "Firefox"
 
#Close the tab
 
 
Once you get into the site, you can download the certificates by following the directions on the page.

This page explains how to setup Arch to use a US Department of Defense Common Access Card (CAC). It was tested with a Dell Smart Card Reader Keyboard and a SCM SCR3310. Others may not work.

Installation

Install ccid and opensc from official repositories.

There are two places in /etc/opensc.conf that comment out enable_pinpad = false. If you card reader does not have a pin pad, uncomment these lines.

Enable pcscd

Start and enable pcscd.service.

Configure browser

Firefox

Load security device

Navigate to Edit -> Preference -> Advanced -> Certificates -> Security Devices and load a module using /usr/lib/opensc-pkcs11.so.

Import the DoD Certificates

If you're using a branded version of Firefox you should be able to go to http://dodpki.c3pki.chamb.disa.mil/rootca.html and click on the high-level certificates to install them and be done.

The primary root certificate used has a CN of "DoD Root CA 2": this certificate can be converted to PEM format for use in other browsers:

  1. Download the CA bundle. This includes approximately 36 certificates. $ curl -O http://dodpki.c3pki.chamb.disa.mil/rel3_dodroot_2048.p7b
  2. Extract the root certificate into a PEM-formatted file.

$ openssl pkcs7 -inform DER -in rel3_dodroot_2048.p7b -print_certs | sed -n '/subject=.*CN=DoD Root CA 2/,${/^$/q;P;D}' > DoD_Root_CA_2.pem

Testing

Visit your favorite CAC secured web page and you should be asked for the Master Password for your certificate. Enter it and if you get in, you know it's working.

Debugging

The pcsc-tools package is also availabe in [community]. The program pcsc_scan may be helpful
