The people who built the Internet love their acronyms – another term that you’ll commonly see discussed when talking about SSL/TLS is HTTPS. Until the web community adopts the TLS terminology, though, you’ll likely continue to see such certificates most often called SSL certificates for simplicity’s sake. Which means that even if you think you installed something called an SSL certificate, you’re likely actually using the more up-to-date and secure TLS protocol. Instead, the actual protocol that is used is determined by your server. Though the web community generally refers to them as SSL certificates out of convenience, certificates are not actually dependent on the specific protocol in their name. Why Aren’t We All Using TLS Certificates Then? Kinsta supports TLS 1.3 on all of our servers and our Kinsta CDN. As for TLS, it’s now on TLS 1.3, which offers a number of improvements to performance and security. At this point, SSL 3.0 is deprecated and no longer considered secure due to its vulnerability to the POODLE attack. SSL version 3.0 was the last public release and was eclipsed in 1999 when TLS was introduced as a replacement. While it was an improvement over the unreleased SSL 1.0, SSL 2.0 also included its own set of security flaws, which led to a complete redesign and the subsequent release of SSL version 3.0 one year later. The first public release of SSL was SSL 2.0 in February 1995. But due to security flaws, it was never released to the public. So where did SSL first come from and how did we get to where we are today with TLS? SSL version 1.0 was developed by Netscape in the early 1990s. For example, Let’s Encrypt (which we’ll discuss more in a second) advertises offering “Free SSL/TLS Certificates.” But you’ll also find plenty of websites simply discussing SSL certificates, even when they actually mean TLS. Nowadays, SSL and TLS are often referred to as a group – e.g. TLS, short for Transport Layer Security, is the successor and more up-to-date version of the original SSL protocol. SSL is closely tied to another acronym – TLS. This leads to a more secure web for both you and the visitors to your website. It’s a protocol used to encrypt and authenticate the data sent between an application (like your browser) and a web server. While we already covered what the acronym means, we’ll dig a little deeper in this entry and tell you what SSL is, as well as how it works to make the web a better place for both you and your website’s visitors. But despite that fact, many webmasters are still unsure how SSL works and why it’s important…or even what SSL stands for in the first place! Because of movements like Encrypt All The Things and Google’s push for more widespread SSL adoption, SSL has been a popular topic in web circles. It’s an important protocol for securing and authenticating data on the Internet.
