IT & Software → Networking → TLS and Certificates → Introduction to TLS and Certificates

Overview

Transport Layer Security (TLS) is a protocol that ensures secure communication over a computer network. It uses certificates to verify the identity of websites and encrypt data, making it difficult for attackers to intercept information. Understanding TLS and certificates is essential for anyone working in IT, as it helps protect sensitive data and maintain privacy online.
