Downloading the Williams certificate authority will let you visit secure Williams websites without getting security warnings from your browser.
Why should I download the certificate?
Many Williams College web sites have purchased certificates from major commercial certificate authorities, such as Geotrust, that let you use the sites without getting a warning message. However it costs several hundred dollars a year for the site to buy a commercial certificate.
Using a Williams College signed certificate is a free alternative. However, it’s slightly less convenient for users, because the users must load the Williams College CA certificate.
NOTE: You only need to load the Williams College CA certificate once per browser. That will handle any site at Williams College that uses the Williams College CA to sign their certificate. This certificate lasts for 25 years, so you should never have to load it again.
So what’s so bad about getting warning messages?
The point of digital certificates is to assure you that you are on a legitimate site. By ignoring the warning messages, you may not realize that you are not actually on the site you think you are. Williams College Networks and Systems urges all users to not ignore these security warnings.
