🔐 What is an SSL Certificate?
An SSL Certificate (Secure Sockets Layer Certificate) is a digital certificate that authenticates a website’s identity and enables an encrypted connection between a web server and a browser. It is a vital security protocol used to protect data transfer and build trust with users online.
🛡️ Why is SSL Important?
When you visit a website with an SSL certificate, you’ll notice:
-
A padlock icon in the address bar
-
The URL starts with “https://” instead of just “http://”
This means the connection is secure, and any information exchanged (like passwords, credit card numbers, or personal data) is encrypted and protected from hackers.
🔍 What Does an SSL Certificate Do?
-
✅ Encrypts sensitive data during transmission
-
✅ Verifies the identity of the website owner
-
✅ Prevents phishing attacks and man-in-the-middle attacks
-
✅ Builds customer trust by showing the site is secure
-
✅ Improves SEO rankings, as Google prefers secure websites
🔑 How Does It Work?
-
A browser attempts to connect to a website secured with SSL.
-
The website sends the SSL certificate to the browser.
-
The browser checks if it can trust the certificate.
-
If valid, an encrypted session begins using keys (public/private).
-
Data transferred between browser and server is now encrypted.
