SSL

SSL is Secure Socket Layer, and is the technology that encrypts web traffic from the web server to the browser to ensure it remains safe in transit.  When you visit "secure" websites, like your banking website, you may notice a pad-lock in your browser window indicating that your traffic is encrypted.  The entire ecommerce industry depends on SSL technology to provide confidence to web visitors that their credit card numbers remain safe.  The online banking community also relies on SSL technology.  In fact, most sites that require a username and password utilize SSL to encrypt traffic.
