What Is an SSL Certificate?
SSL stands for Secure Sockets Layer. An SSL certificate is a digital certificate that creates a secure connection between a website and a user's browser.
When a website has an SSL certificate installed:
Website URLs begin with HTTPS instead of HTTP. A padlock icon appears in the browser address bar. Data transferred between users and the website is encrypted.
SSL certificates verify the identity of a website and protect sensitive information from being intercepted by hackers.
How Does an SSL Certificate Work?
SSL works through encryption technology that secures communication between a browser and a web server.
The process involves:
- Browser Requests Website Security
When a user visits an HTTPS website, the browser requests verification from the website server.

The server provides its SSL certificate containing important information such as:
Website identity Certificate authority details Encryption keys Validity period
- Browser Verifies Certificate

- Secure Connection Is Created
Once verified, an encrypted connection is established, allowing safe data transfer.
This process happens within seconds and protects users automatically.
