What is Transport Layer Security (TLS)? A COMPLETE GUIDE ABOUT TLS
A COMPLETE GUIDE ABOUT TLS
The first TLS version was established in 1999. TLS is a Transport Layer Security that is a widely adopted security protocol. It is designed to ensure privacy and data security for communication over the Internet. The primary and main purpose of TLS is encrypting the communication between web applications and servers.
TLS also provides encryption to other communication modes like emails, messaging, and voice over IP. It was proposed by the Internet Engineering Task Force (IETF). In 2018, the most recent version of TLS 3.0 was published. TLS is valuable because it provides security to both the user and client by encrypting the information.

WHAT DOES TLS DO?
Three major security problems while sending information online are:
– How can we identify that the person whom we are communicating is the one who they say?
– How can we know the data hasn’t tampered which they sent?
– What will be the ways of preventing data from other people?
These issues are very crucial and can create a big mess if even a single issue is not identified properly. A good range of cryptographic techniques is used by TLS to address these problems. They check the data integrity of the third party in connection and provide encryption to information.
For instance – one person simply transfers some payment to his/her relative friend that lives across the country; then one will surely be worried about the problems mentioned above. TLS fulfills all these process requirements of the person. TLS handshake is the way through which authentication takes place and keys are established.
