USE YOUR CAC ON A CHROME Operating System computer

Chrome OS logo

 

Utilizing your CAC with Chrome OS "may" work if you follow these instructions

You should be able to access most CAC enabled websites.  However, I am unable to find Adobe Reader to be able to digitally sign PDF forms

NOTE:  This was last tested / validated on 14 August 2022 with Chrome OS version 104.0.5112.83 using an SCR-3310 v2.0 CAC reader with the GEMALTO DLGX4 128Kv2 CAC utilizing the CSSI Smart Card Connector (available below)

NOTE2: Starting with the 103.0.5060.132 version, Google has made this process much longer, as in I used to have only 4 files below.  Now you see many more.

Step 1: Download these 4 DoD certificate files to your computer

If you have a version BEFORE 103.0.5060.132 use these 4 files:

AllCerts.p7b,

RootCert3.p7b,

RootCert4.p7b and

RootCert5.p7b

Everyone with 103.0.56060.132 and newer use these files:

DoD Derility CA-1

DOD EMAIL CA-49

DOD EMAIL CA-50

DOD EMAIL CA-51

DOD EMAIL CA-52

DOD EMAIL CA-59

DOD EMAIL CA-62

DOD EMAIL CA-63

DOD EMAIL CA-64

DOD EMAIL CA-65

DOD ID CA-49

DOD ID CA-50

DOD ID CA-51

DOD ID CA-52

DOD ID CA-59

DOD ID CA-62

DOD ID CA-63

DOD ID CA-64

DOD ID CA-65

RootCert3.p7b,

RootCert4.p7b

RootCert5.p7b

DOD SW CA-53

DOD SW CA-54

DOD SW CA-55

DOD SW CA-56

DOD SW CA-57

DOD SW CA-58

DOD SW CA-60

DOD SW CA-61

DOD SW CA-66

DOD SW CA-67

DOD SW CA-68, and

DOD SW CA-69

 

Step 2: To install the certificates in Chrome, select the 3 dots (top right of web browser), select Settings

Options, Settings

 .

Step 3: Select Privacy and security (left side of screen),

.

Scroll down to Privacy and Security, then select Security

 

 

 

Step 4: Scroll down and click on Manage certificates under Advanced

ChromeOS Advanced 

 

 

 Step 5: Click the Authorities (tab)

Manage Certificates

 

.

 

 Step 6: Click IMPORT

Import

 

 

Step 7: Navigate to the folder you downloaded the above files to, then change the drop down (found in lower left corner of page) to:  All files

All Files

 

 

 Step 8: Select RootCert5.p7b, then click OPEN

NOTE:  Install the files in this order: 

RootCert5.p7b,

RootCert4.p7b,

RootCert3.p7b,

AllCerts.p7b, or now each of the remaining certificates

by selecting each and clicking OPEN

NOTE: RootCert2.p7b is no longer used

Selecting RootCert4 

 

 

Step 9: Check all three boxes under Trust settings, click OK

3 boxes

 

 

Step 10: Install the other files you downloaded by going back to IMPORT

Import

 

 

Step 11: Repeat steps 7, 8, & 9 for each of the downloads

Reminder to OPEN in this order:

RootCert4.p7b,

RootCert3.p7b,

and finally AllCerts.p7b or now each of the remaining certificates by selecting each and clicking OPEN

NOTE: RootCert2.p7b is no longer used

Rest of the files

 

 

Step 12: To verify all certificates installed...  Stay in the AUTHORITIES (tab), scroll down to org-U.S. Government, the certificates listed below should be there:

DOD DERILITY CA-1

DOD EMAIL CA-49 through DOD EMAIL CA-52,

DOD EMAIL CA-59,

DOD EMAIL CA-62 through DOD EMAIL CA-65 

DOD ID CA-49 through DOD ID CA-52,

DOD ID CA-59,

DOD ID CA-62 through DOD ID CA-65

DoD Root CA 3 through DoD Root CA 5,

DOD SW CA-53 through DOD SW CA-58,

DOD SW CA-60 through DOD SW CA-61, and

DOD SW CA-66 through DOD SW 69

 

Step 13: All of the DoD certificates are now installed, the next step is to install CSSI Smart Card Middleware.  CSSI requires two separate apps be installed.

NOTE:  CSSI Smart Card Middleware has worked more consistently (in my tests)

 

Download CSSI Smart Card Middleware from the Google webstore: https://chrome.google.com/webstore/detail/cssi-smart-card-middlewar/haeblkpifdemlfnkogkipmghfcbonief?hl=en

 

Download Smart Card Connector from the Google webstore:

https://chrome.google.com/webstore/detail/smart-card-connector/khpfeaanjngmcnplbdlpegiifgpfgdco?hl=en

 

Select + ADD TO CHROME on each app 

CSSI

 

Click the Add app (button)

Add App

When going to CAC enabled sites, it is a little slow

I used an SCR-3310 v2.0 CAC reader

You may have to Allow the app

 

If you'd like to let me know of your success, fill out this form.

 

Alternate Step 13: NOTE: CACKey is another program you can use.  DO NOT install both CSSI and CACKey. 

NOTE:  I have found CSSI to work more consistently than CACKey.

CACKey is available by going to this webstore link:  https://chrome.google.com/webstore/detail/cackey/lpimdiknnpijeigckalekdccibdmeojg

Select the + ADD TO CHROME (button)

CACkey  

Click the Add app (button)

Add App

 

 

When you want to use it, select LAUNCH APP

 

NOTE: If you are unable to access your DoD websites...

  I have been informed by some personnel that they had to use Incognito mode to access some DoD websites.  If you want to try this:

Option 1:  Click <shift> <ctrl> <n>

Option 2: "Double finger tap" on the Chrome browser icon in the taskbar

 

Step 14: When selecting your CAC certificate, make sure you select the one without the word EMAIL in it.  As all DoD websites are using the Authentication certificate.

 

NOTICE: 

Many Navy, Marine, and Air Force Mac users are having issues accessing their email via OWA and a few other CAC specific websites once getting a new CAC (or when migrated to O365).  I have not found a fix for Chrome OS users.
