SSL
Definition
The security protocol that encrypts data between browsers and servers, shown by the padlock icon.
In Plain English
SSL is like a sealed envelope. Without it, sending data is like writing on a postcard anyone can read.
Real-World Example
When customers enter credit card information on your site, SSL encrypts it so hackers cannot intercept it.
Why It Matters for Your Work
Sites without SSL show "Not Secure" warnings, damaging trust. Google also ranks SSL sites higher in search results.
Common Mistake
Thinking SSL is only needed for e-commerce. Any site collecting data (even contact forms) should use SSL.
