Transport Layer Security
Transport Layer Security or TLS refers to a protocol that confirms privacy between communicating applications and their users on the Internet. Whenever a server and a client connect, the transport layer security confirms that no third party is able to meddle with any message. TLS is a heir to the Secure Sockets Layer or SSL.
TLS comprises of two layers: the TLS Record Protocol and the TLS Handshake Protocol. The TLS Record Protocol offers connection security with certain encryption technique such as the Data Encryption Standard or DES. The TLS Record Protocol can also be utilized without encryption. The TLS Handshake Protocol permits the server and client to validate each other and to discuss an encryption algorithm and cryptographic keys before the actual data is exchanged.
