SSL (Secure Sockets Layer) is a security technology that encrypts data between a website and its visitors.
Today, SSL is mostly implemented using a newer protocol called TLS, but people still commonly say “SSL certificate.”
Simple Explanation
SSL protects information sent between:
- your browser
- and a website server
It keeps data private and secure.
Without SSL:
- hackers may intercept data
With SSL:
- the connection is encrypted.
How to Recognize SSL
Websites with SSL use:
https://
instead ofhttp://
You’ll also usually see:
- a padlock icon in the browser.
Example:
✅ https://example.com
❌ http://example.com
