The Secure Sockets Layer (SSL)/ Transport Layer Security (TLS) is another popular protocol that can encrypt user data that travels through the internet. It makes a vast number of different online communications possible.
TLS is a successor of SSL and both provide security features and encryption which enable commerce to take place in the online world. Unlike some of the lesser-known protocols, SSL and TLS have both received several updates over the years. That has allowed SSL and TLS to remain secure even today.
Most entities that implement SSL do so in a combination with TLS. TLS is responsible for encrypting online traffic. Users who access websites via HTTPS addresses get protection from TLS. However, many other applications use TLS as well, such as Usenet and email.
