TLS / SSL - The complete sequence - Practical TLS

Understanding SSL and TLS

This section delves into the interactions between the client, server, and certificate authority in SSL/TLS processes.

Certificate Authority Role

  • The Certificate Authority (CA) is pivotal in SSL/TLS, possessing an asymmetric key pair and a self-signed certificate.

Server Identity Verification

  • Servers like websites or VPN clients prove their identity by generating public-private key pairs and creating a CSR.

Certificate Generation Process

  • The CA verifies server information in the CSR to issue a signed certificate tying keys to identity.

Client Interaction and Handshake

This part explores how clients interact with servers post-certificate issuance.

Client Validation Steps

  • Clients validate certificates by checking signatures using CA's public key and ensuring server ownership.

SSL Handshake Process

  • During the handshake, clients verify certificate legitimacy and server ownership through private-public key matching.

TLS/SSL Process Overview

A high-level view of the TLS/SSL process is presented here.

Symmetric Key Establishment

  • Successful handshakes establish symmetric encryption keys for data confidentiality and integrity.

Secure Data Transfer

  • Session keys created during handshake enable secure data transfer between client and server through encryption.
Video description

Understanding TLS/SSL involves understanding the interaction between the Client (web browsers, SSL VPN clients, etc...), the Server (websites, VPN endpoints, etc), and the Certificate Authority (the entity that issues Certificates). This video outlines the exact sequence of events that occur in the TLS ecosystem, and will explain the function of the Certificate, CSR, Public Key, and Private Key. Seeing the whole process at 10,000 ft view will help you understand the smaller individual working parts as we continue to dive deeper and deeper into TLS and SSL.
