How HTTPS Works Explained | HTTP vs HTTPS | TLS Handshake (TLS 1.2 vs 1.3)

n this video, we break down how HTTPS works — from the basics of HTTP vs HTTPS to the full TLS handshake process step-by-step. 🔹 Learn how browsers and servers create a secure encrypted connection using asymmetric and symmetric cryptography. 🔹 Understand every phase: – TCP Handshake – Certificate Exchange & Warnings – Key Exchange (Session Key Generation) – Encrypted Data Transmission 🔹 Finally, we’ll compare TLS 1.2 vs TLS 1.3, so you know exactly how modern HTTPS is faster and safer. 🧠 Topics Covered: 00:00 – Introduction 00:28 – HTTP vs HTTPS (Port 80 vs 443, SSL vs TLS) 02:00 – how https works? 02:20 – TCP handshake? 03:16 – Certificate Verification 06:52 – Certificate Warnings 07:58 – Key Exchange & Encryption Explained 10:00 – Data Transmission (Symmetric Encryption) 11:15 – TLS 1.2 vs TLS 1.3 Difference ⚡ You’ll Learn: • Why HTTPS is secure and HTTP isn’t • How SSL/TLS handshake actually works • How certificates prevent Man-in-the-Middle attacks • What happens when a certificate is invalid • Why TLS 1.3 is faster and more private 📚 Perfect for students of Cybersecurity, Networking, or Ethical Hacking — or anyone who wants to understand how their data stays safe online. 👉 Don’t forget to like, comment, and subscribe for more easy cybersecurity tutorials! #HTTPS #TLS #CyberSecurity #SSL #Networking #Encryption
