This network employs a technology called SSL filtering which allows your network's administrators to filter out harmful or inappropriate Web content such as viruses and pornography. In order for this technology to work effectively, the network's filtering unit must issue to your computer or mobile device a file called an SSL certificate.
This guide will help you install the SSL filtering certificate for Chome-based browsers which do not use the operating system's built-in key store — this includes Chrome OS and Chrome for Linux.
First, click the Download Certificate button; this will download the certificate file to your computer. Visit your domain's portal page to download a certificate. By default, this is https://portal.cipafilter.com.
Depending on your configuration, you may be prompted to save the certificate. If so, select a folder to save the file in, and then click Save. (In Chrome OS and some other configurations, the file may simply download immediately.) When the download has finished, the icon will flash in the download bar at the bottom of the screen.
(Note: These images show Chrome running on Chrome OS version 23; you may not see exactly the same thing if you are using Chrome for Linux; however, the general process and wording should be the same.)
Do not double-click the file after the download has finished; instead, click the Chrome menu (usually appearing as three horizontal lines) in the top right corner. Then, click the Settings option.
The Chrome Settings page will open in a new tab. If necessary, scroll all the way down to the bottom; then, click the Show advanced settings link.
The Settings page will expand to reveal several new options. Scroll down nearly to the bottom and click the Manage certificates... button.
When the Certificate manager screen appears, click the Authorities tab. Then, click the Import... button near the bottom.
A file browser will appear, allowing you to select the certificate. Locate the certificate you downloaded previously (it may be in a folder called Downloads), and double-click to open it.
A prompt will appear asking whether to trust the certificate authority. Select Trust this certificate for identifying websites and then click OK.
You're done! After trusting the CA, you can click OK, close the Settings page, and continue browsing as usual; in most cases, you will not notice anything different after the certificate is installed.
