<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.
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.
Postcard (HTTP)
Anyone can read it
Sealed Envelope (HTTPS)
Only recipient can read
Mailbox (Server)
Receives the message
Encrypts Data
Secure Channel
Decrypts Data
Browser requests secure connection
Connects to website with HTTPS
Server sends SSL certificate
Proves the server's identity
Browser verifies certificate
Checks if certificate is valid and trusted
Encryption keys exchanged
Both sides agree on encryption method
Secure communication begins
All data is encrypted end-to-end
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.
