Transport Layer Security (TSL) TLS is the successor to Secure Sockets Layer (SSL): SSL is a standard protocol for encryption and security. It provides a secure and encrypted connection between the computer and the target server or device accessed over the Internet. and offers a stronger and more stable security Encryption is the process by which data is made illegible and unusable for unauthorized viewers. In order to use or read encrypted data, you must decrypted will. A secret key is required for this. There are two types of top-level encryption: symmetrical and asymmetrical . In the symmetric encryption the same key is used to encrypt and decrypt the data.... protocol. Based on the IETF (Internet Engineering Task Force) standard, the protocol is designed to prevent forgery, manipulation and spying on messages. It is typically used to protect web browser communications, email, VoIP, and instant messaging. Although TLS is used these days, this newer security protocol is often still called SSL.
