HTTP vs HTTPS vs SSL vs TLS — How Secure Web Actually Works

What are HTTP, HTTPS, SSL, and TLS — and how do they actually work? In this video, you’ll learn the fundamentals of web security step by step in a clear and simple way. Every time you visit a website, your browser communicates with a server — but how is your data actually protected? We’ll build your understanding from the ground up: ◼️ First, you’ll learn what HTTP is and why it’s not secure. ◼️ Then, we’ll move on to HTTPS and see how it protects your data. ◼️ After that, we’ll explain the difference between SSL and TLS. ◼️ Next, we’ll break down the TLS handshake step by step. ◼️ Finally, you’ll understand how the Diffie-Hellman algorithm allows secure key exchange. ⏱️ Timestamps 0:00 - Introduction 0:17 - What is HTTP? 1:16 - What is HTTPS? 2:14 - SSL vs TLS Explained 2:57 - TLS Handshake Explained 4:19 - Diffie-Hellman Algorithm ✅ Free Python Courses    / @turtlecode   By the end of this video, you’ll have a clear understanding of how secure communication on the internet actually works — without unnecessary complexity.
