What is TLS

TLS Stands for Transport layer security and is a Successor of SSL which stands for Secure Socket Layer, TLS is a way which provides you secure communication over Internet for email, faxing, Instant messaging and other data transfer. This protocol resides on application layer protocol, and involve encryption scenarios.

TLS is a set of rules which helps you a lot when you are communicating over Internet via Instant messaging, online fax, VOIP (Voice Over IP) and emails by providing you lots of end to end security. TLS is a successor of SSL and mainly resides on application layer. TLS uses handshake protocol to authenticate server and client before sending or encrypting any message. In TLS only server deploy public key to authenticate server so that no third party or intruders may eavesdrop any message or communication in order to save message forgery.

There is no major difference between TLS and SSL, just some minor enhancement has done with SSL to improve reliability and security. In fact TLS is composed by two protocol layers one is TLS record protocol and another is TLS handshake protocol.
TLS Record protocol provides connection security with encryption methods like DES(Data Encryption Standard), it can also be use without any encryption. Whereas TLS Handshake protocol does client and server authentication, which allow server and client to authenticate each other to negotiate any encryption and keys before data is exchanged.

When we use internet to communicate via message or VOIP, it is mandatory to aware with such technologies, to ensure communication reliability. TLS works behind the scene and provides us secure communication, mainly server is authenticated in TLS. Now all latest browser supports TLS.
