4.1 What is SSL, anyway? SSL stands for Secure Socket Layer. It was invented at Netscape as a means of encrypting data that is to be sent over HTTP (hypertext transfer protocol) connections. Whenever you visit a site whose URL (Uniform Resource Locator) begins with https:// (rather than the usual http://) you are dealing with a potentially secure site. Ideally, SSL is transparent to the user. When you access a secure site, your browser and the server should negotiate a suitable encryption method and then your surfing should continue uninterupted. Like Netscape and Microsoft Internet Explorer, there is a visual change in the Voyager V2.95 GUI when you are accessing a secure site: it displays a small icon of an unbroken key in the lower-left hand corner of the screen when you are surfing a secure site. If in doubt, check the URL box. If it begins https://, then chances are you are surfing securely.
