HyperText Transfer Protocol Secure (HTTPS)

📍HTTPS (HyperText Transfer Protocol Secure) is a secure version of HTTP, the protocol used for loading web pages. It uses encryption to protect the data sent between your browser and a website.

How HTTPS Works

HTTPS uses a technology called SSL/TLS encryption. This means:

  • Data (like passwords, credit card numbers, or messages) is scrambled during transfer;
  • Only the intended recipient (usually a website) can read the information;
  • It prevents hackers from stealing or tampering with your data while it’s in transit.

The connection is verified using a digital certificate, issued by a trusted Certificate Authority (CA). You can spot HTTPS in the browser by the lock icon and the URL starting with “https://”.

Why HTTPS Matters

  • 🔐 Protects sensitive data, like logins and payment details.
  • 🧑‍⚖️ Confirms website identity through SSL certificates.
  • 🛡️ Guards against man-in-the-middle attacks.
  • 📈 Helps SEO, since Google gives preference to secure sites.
  • 🌐 Builds user trust — many browsers now label non-HTTPS sites as “Not Secure.”

A Quick Example

You visit an online store to buy a gift. The site uses HTTP, and your payment data could be intercepted. But if it uses HTTPS, your personal information is encrypted and protected while being sent to the store’s server.
