SSL/TLS (Secure Sockets Layer/Transport Layer Security) is a cryptographic protocol designed to provide secure communication over a computer network. It ensures data encryption, identity verification, and integrity checks between clients and servers.

Key Concepts

  • Data Encryption
    SSL/TLS encrypts data transmitted between devices using asymmetric and symmetric encryption algorithms.

  • Handshake Protocol
    The TLS handshake establishes a secure connection by negotiating encryption parameters and exchanging keys.
