When using client certificates in Chrome, one of the great annoyances is that it prompts you each time you first go to the secured site per session. This is of course preferred as a security step to confirm you are connecting with the correct certificate, but you can also configure Chrome to use the certificate you selected for each site.
To accomplish this, in Windows 7, we will be adding a registry keys via regedit. You will need to first open the Registry Editor by going to Start, then start typing in the lower search box “regedit”. Once the registry editor is opened, you will need to create a Google key, Chrome Key, and a AutoSelectCertificateForUrls key so it vaguely looks like the following example. You may have many, many, many programs under SOFTWARE and Policies, just right mouse click on Policies and choose New then Key.
Next you need to add the values to the AutoSelectCertificateForUrls key. Right mouse click on the large white space on the right side of the screen and choose New, then String. Name the new string 1 and add the following to the value:
Where https://example.com is the URL of the site you are accessing, and CertName is the CN name from the certificate you are using.
Once you are finished, it should look something like this.
