How SSL certificates work.
1. The SSL agreement.
When a visitor enters an SSL-protected website, your SSL certificate automatically creates a secure, encrypted connection with their browser. Your site is most secure when SSL is deployed on all pages and subdomains.
2. The padlock icon appears.Once the connection is complete, a padlock icon and https prefix appear in the visitor’s browser bar to show visitors to your website they’re safe to browse, shop, email you, subscribe to your mailing list, etc.
3. Now you’re good to go.
All information passing to and from your website is now encrypted, making your sensitive data virtually unhackable.
