Transport Layer Security (TLS) is a cryptographic protocol designed to provide secure communication over a computer network. It is widely used to protect data transmitted between a client (such as a web browser) and a server (such as a web server), ensuring privacy, data integrity, and authentication. ### Key Features of TLS: 1. **Encryption**: TLS encrypts the data being transmitted, which helps protect it from eavesdroppers and man-in-the-middle attacks.

Transport Layer Security creates a protected channel between protocol peers. The application determines the intended peer and how its authentication is interpreted; a provider-authorised CDN edge can be such a peer. Channel protection does not make that peer unable to read data delivered to it.[ref]
