if you’re not familiar with SSL, perhaps you’ve seen websites that have https:// instead of http://. That “s” tells visitors the website uses SSL, and the information passed to that site’s server will remain private. SSL stands for Secure Sockets Layer, and the letters “https” stand for “Hypertext Transfer Protocol, Secure.” Additionally, another indicator a website has SSL is a padlock icon to the left of the address bar, or a “green bar” in the URL.
When data is transmitted through a website to a server or browser, SSL adds a layer of protection through encryption. Sensitive information like passwords, credit card numbers, banking information, email addresses and other critical data is protected through SSL’s encryption process. SSL protocols encrypt the data before its transmitted, rendering it worthless to anyone attempting to intercept it as it travels through the interwebs. SSL also verifies both sender and receiver of data to each other. In fact, many of the most common phishing or spoofing scams are more challenging for hackers to pull off on a site that has SSL protection.
