What Is HTTPS Really? (HTTP, TLS & Web Security Explained) | Internet A-Z | Episode 8

When you see the 🔒 lock icon in your browser, you probably assume the website is safe.
But is it?
In this episode of the Internet A–Z series, we break down the real difference between HTTP and HTTPS — not just at the surface level, but at the architectural level.
You’ll understand:
What HTTP actually is
Why it was never designed for security
How unencrypted traffic can expose usernames and passwords
What HTTPS really means (HTTP over TLS)
How the TLS handshake works conceptually
The difference between encryption and trust
Why HTTPS does NOT guarantee a website is legitimate
We also connect the dots between:
DNS → IP → TCP → TLS → HTTP
So you can finally see how the modern web works as a system.
This episode reinforces everything we’ve covered so far — and prepares you for the final episode:
“Browsers: What Happens After You Press Enter”
If you want to truly understand how the Internet works — not just use it — this one is essential.
Happy Networking.
