When a visitor goes to your site, their web browser will look for your site’s SSL/TLS certificate. Planned deprecation in 2020. You can click below to jump to a specific section or read through the entire article: TLS, short for Transport Layer Security, and SSL, short for Secure Socket Layers, are both cryptographic protocols that encrypt data and authenticate a connection when moving data on the Internet. Online Storage or Online Backup: What's The Difference? The change comes at an interesting time, too, considering the recent push for browsers and servers to support TLS. Starting with Chrome version 62, all websites with text input fields will need an SSL certificate or Google will mark the website as not secure with a red caution sign next to the URL. SSL is older than TLS, but all SSL certificates can use both SSL and TLS encryption. We test each product thoroughly and give high marks to only the very best. Instead of agreeing on an encryption model, the server provides the encryption key with TLS 1.3. In fact, Google started showing ERR_SSL_OBSOLETE_VERSION warning notifications in Chrome. Kinsta, for example, has already addressed the release of TLS 1.3 and is taking steps to implement it (read our Kinsta review). Why is it called an SSL certificate and not a TLS certificate? If you enjoyed this tutorial, then you’ll love our support. The same process is happening, a handshake between two machines, but the version of protocol determines how it happens. Once again, SSL certificates are better defined as “certificates that can use SSL and TLS,” so we’ll call them SSL certificates to avoid confusion for this section. Planned deprecation in 2020. TLS is the new protocol for secured encryption on the web maintained by IETF. The handshake includes the cipher, authentication and key exchange. And yes, you should use TLS instead of SSL. Even in 2019, the following browsers still lack TLS 1.3 support: But while TLS 1.3 still doesn’t have full adoption, all major browsers support TLS 1.2 in 2019: By having both TLS 1.3 and TLS 1.2 enabled on your server, you can ensure compatibility no matter what, while still getting the benefits of TLS 1.3 for browsers that support it, like Chrome and Firefox. And yes, you should use TLS instead of SSL. So what’s the difference between TLS vs SSL? It’s important to use the latest versions of TLS because SSL is no longer secure, but your certificate does not determine the protocol that your server uses. And SSL is the predecessor of TLS. SSL 2.0 – released in 1995. Here are some resources that will help you dig deeper into SSL, TLS, and STARTTLS: Wikipedia’s entry on SSL and TLS: This is a good overview of the history of the encryption protocols and their technical details.
