You may have heard about TLS, TLS 1.2, TLS 1.3 or SSL Certificates, etc. What are they? Well, first off, we need to know what TLS and SSL stand for, then we can dive deeper.
TLS stands for Transport Layer Security. TLS is a security protocol that will provide security and encryption between web sites or applications and the servers and browsers that are being used to look at the site. It can also be used in other applications such as email, instant messengers or even VoIP (voice over IP) phone calls.
That’s all well and good but what exactly is it?
Well, TLS is an encryption protocol. The first version of it (TLS 1.0) came about back in 1999 by the Internet Engineering Task Force (IETF). More on them later. The latest version of TLS by the way is TLS 1.3 however; there are a lot of companies out there that don’t quite support that version as of yet. The most common version is TLS 1.2 and you should see at the very least that version on a lot of sites out on the internet.
