Transport Layer Security is the successor of SSL as cryptographic protocol and is largely deemed as more effective and secure than SSL. It encrypts the sessions using message authentication codes, symmetric encryption, etc.
It enables server and client to communicate across a network and secures that connection from tampering or eavesdropping. After the server and client decide on TLS usage, a connection will be attempted through a so-called “handshake” where the two will agree on different parameters needed in establishing connection. Because of this, TLS is widely used in web browsing, fax, VoIP, messages and email.
Its major use is in security for web traffic through HTTP (which is denoted as HTTPS), something that is essential in e-commerce, and in mail transfer (SMTP) which is secured by TLS via public key.
