Real-world usage

Protocol Explorer

Algorithms like AES and RSA rarely operate alone. They are combined into robust protocols to secure the internet. Explore how the most common protocols work step by step.

TLS (Transport Layer Security)

Secure communication over a computer network, widely used for web traffic (HTTPS).

Actors

Client (Browser), Server

Key Concepts

Handshake, X.509 Certificates, Forward Secrecy, AEAD

Protocol Flow

Step 1 of 4

Client

Server

ClientHello + Random_C

How it compares

Typically only authenticates the server (via Certificate Authorities) rather than both parties, unlike SSH.
