Appendix A Importing Certificates - ZyXEL Communications NWA90AX User Manual

This appendix shows you how to import public key certificates into your web browser.
Public key certificates are used by web browsers to ensure that a secure web site is legitimate. When a
certificate authority such as VeriSign, Comodo, or Network Solutions, to name a few, receives a
certificate request from a website operator, they confirm that the web domain and contact information
in the request match those on public record with a domain name registrar. If they match, then the
certificate is issued to the website operator, who then places it on the site to be issued to all visiting web
browsers to let them know that the site is legitimate.
Many Zyxel products, such as the Zyxel Device, issue their own public key certificates. These can be used
by web browsers on a LAN or WAN to verify that they are in fact connecting to the legitimate device
and not one masquerading as it. However, because the certificates were not issued by one of the
several organizations officially recognized by the most common web browsers, you will need to import
the Zyxel-created certificate into your web browser and flag that certificate as a trusted authority.
Note: You can see if you are browsing on a secure website if the URL in your web browser's
address bar begins with https:// or there is a sealed padlock icon (
in the main browser window (not all browsers show the padlock in the same location).
Google Chrome
The following example uses Google Chrome on Windows 7. You first have to store the certificate in your
computer and then install it as a Trusted Root CA, as shown in the following tutorials.
