What is SSL?
SSL (Secure Sockets Layer) is a technology that helps secure the connection between a website and its visitors. When you visit a website, your computer communicates with the website’s server, sending and receiving data. Without SSL, this data can be intercepted by hackers. SSL protects this information, ensuring that it stays private and safe.
How Does SSL Work?
1. Establishing a Secure Connection:
When you visit a website with SSL (you’ll notice this when the URL starts with “https”), your browser first checks whether the website has an SSL certificate. This certificate is like an ID card that verifies the website is safe.
2. Data Encryption:
Once the browser confirms the website’s SSL certificate, it creates an encrypted connection. Encryption means that any data sent between your browser and the website (such as passwords, credit card information, or personal messages) is scrambled into unreadable code. Only your browser and the website’s server can understand it.
3. Data Decryption:
When the website receives your encrypted data, it has a special 'key' to decode it back into its original form. This ensures that even if hackers intercept the data, they can’t read or use it.
Why Is SSL Important?
- Security: SSL keeps your information safe from hackers.
- Trust: Websites with SSL show a padlock icon next to the URL, letting users know it’s secure. This builds trust with visitors.
- SEO Benefits: Search engines like Google prefer secure websites, so having SSL can help improve your website’s ranking.
