HTTPS Explained

1

What is it?

<strong>HTTPS (HTTP Secure)</strong> is the secure version of HTTP. It encrypts data between your browser and the website using SSL/TLS, preventing hackers from reading or modifying your information.

Think of it like...

The Sealed Envelope Analogy

HTTP is like sending a postcard—anyone handling it can read your message. HTTPS is like a sealed envelope—only the intended recipient can open and read it.

📧

Where you see it

1

Browser requests secure connection

2

Server sends SSL certificate

Proves the server's identity

3

Browser verifies certificate

4

Common Mistake

Wrong

"HTTPS makes my website slower" or "HTTPS is only for e-commerce"

Correct

HTTPS is <strong>essential for ALL websites</strong>. Modern browsers mark HTTP sites as 'Not Secure', and HTTPS has minimal performance impact while providing crucial security and SEO benefits.

💡 Real-World Example

When you log into your bank:

1

HTTPS encrypts your username and password

2

Hackers on public WiFi can't steal your credentials

3

The padlock icon in your browser confirms the connection is secure

4

Your bank's identity is verified by a trusted certificate authority
