CAC Reader Installation Guide

Installing a Common Access Card (CAC) reader is a straightforward task. If you follow the steps methodically, you’ll be using your CAC reader in no time. This guide covers different operating systems: Windows, macOS, and Linux. It will also introduce some common troubleshooting methods.

Windows Installation

Step 1: Identify the type of CAC reader

First, determine the kind of CAC reader you have. These generally connect via USB. Visit the manufacturer’s website for the latest drivers if you don’t have the installation CD.

Step 2: Download the driver

Once you’ve identified your reader, download the driver from the manufacturer’s site. This software allows your computer to communicate with the CAC reader.

Step 3: Install the driver

Run the downloaded file to install the driver. Follow the on-screen instructions. You’ll typically just need to click Next through several screens and accept the license agreement.

Step 4: Plug in your CAC reader

Insert the CAC reader into a USB port. Windows should recognize the device and complete the installation. If prompted, restart your computer.

Step 5: Test your CAC reader

Insert your CAC into the reader. Open a web browser and visit a site that requires CAC authentication. If the site recognizes your CAC, your installation is successful.

macOS Installation

Step 1: Connect your CAC reader

Plug the CAC reader into a USB port on your Mac. Modern macOS versions often recognize the device immediately. However, you might still need specific drivers.

Step 2: Download necessary drivers

Visit the manufacturer’s website to download macOS-compatible drivers. Sometimes, drivers are not necessary as macOS has built-in support for many readers.

Step 3: Install required software

Install the downloaded drivers. Follow the on-screen instructions. If prompted, reboot your Mac after installation.

Step 4: Configure Keychain Access

Open “Keychain Access”, located in the Applications/Utilities folder. Go to “Preferences” and select the “Certificates” tab. Set “OCSP” and “CRL” to Best Attempt. Close the and restart your Mac.

Step 5: Test your CAC reader

Insert your CAC into the reader and try accessing a CAC-enabled site in Safari. Your Mac should prompt you for your PIN if the reader and CAC are functioning correctly.

Linux Installation

Step 1: Connect CAC reader

Connect your CAC reader to a USB port. Most modern Linux distributions automatically recognize USB devices.

Step 2: Install necessary packages

Open a terminal window. Install required software using your package manager. For Ubuntu and Debian-based systems, use:

sudo apt-get install pcscd pcsc-tools libccid

Step 3: Enable and start pcscd service

Ensure the service is running. In your terminal, execute:

sudo systemctl enable pcscd
sudo systemctl start pcscd

Step 4: Test your CAC reader

Use the pcsc_scan command to check if your reader is recognized:

pcsc_scan

If your reader appears in the output, it’s working.

Step 5: Configure Firefox

Open Firefox and type about:preferences in the address bar. Navigate to the “Certificates” section. Click “Security Devices” and then “Load”. Enter a module name (e.g., “CAC Module”) and the module filename:

/usr/lib/x86_64-linux-gnu/opensc-pkcs11.so

Click “OK”, then restart Firefox. Visit a CAC-enabled site to test functionality.
