Show Suggested Answer Hide Answer
Suggested Answer: D 🗳️
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network. It uses X.509 certificates and hence asymmetric cryptography to authenticate the counterparty with whom it is communicating, and to exchange a symmetric key. The TLS protocol allows client-server applications to communicate across a network in a way designed to prevent eavesdropping and tampering.
