#121 - Web TLS Protocol

The TLS (Transport Layer Protocol) is used by the web browsers for authentication of the server and client as well as encryption of data. The current latest version is 1.3 and the previous versions are 1.2, 1.1 and 1.0.

TLS (and its predecessor SSL) are located in the Presentation Layer of the OSI Model and in the Application Layer of the TCP/IP model.
