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

Описание: 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.
