SSL (Secure Sockets Layer) is the standard security technology for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private and integral. SSL is an industry standard and is used by millions of websites in the protection of their online transactions with their customers.
My previous site did not use SSL, however it also didn’t collect or transmit any personal information, and any payment information and transactions took place entirely on PayPal’s server, so I was never privy to any personal data or financial information. Nevertheless, I felt it was time to fully encrypt all traffic for the entire website and get myself an SSL certificate. This is fast becoming the norm, probably largely accelerated by the fact that Google even regards SSL as a factor that influences rankings in search results. So as of today, you should see the little padlock in the URL bar of your browser.
