What is SSL Certificate?
A digital certificate that enables encrypted connections and proves your website's identity.
Why It Matters
SSL certificates are required for HTTPS and the browser padlock icon that users expect to see.
Real-World Example
Using a free Let's Encrypt certificate to enable HTTPS on your website.
“Understanding terms like SSL Certificate matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
