TLS – what does it stand for? TLS is Transport Layer Security protocol and this protocol ensures safe and secure communication between a user and an application.

It certainly easies the communication between these two as no third party can involve itself in the process and spy on the communication between them. SSL is the predecessor of TLS.

SSL is short for Secure Sockets Layer and this protocol later became a process of TLS. There are several different ways in which TLS can function and one way is symmetric keys and data encryption. Now, if you are browsing over the Internet, noticing in your address bar the letter “s” next to the “http” means that it’s protected with the TLS protocol.

When you as a user communicate with certain applications over the web, the TLS will install a symmetric key which is later discarded after you exit.

This way, there is no chance of someone to guess or find that symmetric key. After the session is over, the key gets discarded and you can safely exit browsing again.
