HTTPS, or HyperText Transfer Protocol Secure, is a protocol used for secure communication over the internet. It’s essentially an enhanced version of HTTP (HyperText Transfer Protocol), the foundation of data exchange on the World Wide Web, but with a critical addition: encryption. This ensures that data sent between your device and a website is protected from eavesdropping or tampering.
Think of HTTPS as sending a letter in a locked box rather than an open envelope. Even if someone intercepts it, they can’t read the contents without the key. This makes it vital for websites handling sensitive information, like online banking or shopping sites.
HTTPS combines HTTP with SSL/TLS (Secure Sockets Layer/Transport Layer Security) to provide three key features:
For example, when you log into your bank account, HTTPS encrypts your password and verifies the site’s identity, keeping your information safe.
HTTPS isn’t just a technical detail—it’s a cornerstone of online security. Here’s why:
Without HTTPS, data sent over HTTP is exposed, making it easy for anyone on the network to intercept.
HTTPS is your first line of defense online. By encrypting data, verifying websites, and ensuring integrity, it keeps your interactions safe.
