The use case for Transport Layer Security (TLS) is to enable a client and a server to establish secure

communications for another protocol. TLS is a cryptographic protocol designed to provide secure

communication over a computer network. It is widely used for web browsers and other applications

that require data to be securely exchanged over a network, such as file transfers, VPN connections,

and voice-over-IP (VoIP). TLS operates between the transport layer and the application layer of the

Internet Protocol Suite and is used to secure various other protocols like HTTP (resulting in HTTPS),

SMTP, IMAP, and more. This protocol ensures privacy and data integrity between two communicating

applications. Detailed information about TLS and its use cases can be found in IETF RFC 5246, which

outlines the specifications for TLS 1.2, and in subsequent RFCs that define TLS 1.3.
