SSL Certificates are small data files that digitally bind a cryptographic key to an organization’s details. When installed on a web server, it activates the padlock and the https protocol and allows secure connections from a web server to a browser. Typically, SSL is used to secure credit card transactions, data transfer and logins, and more recently is becoming the norm when securing browsing of social media sites.
Your domain would be hosted vis HTTPS instead of just HTTP and would have a padlock sign attached to it.
SSL Certificates bind together:
- A domain name, server name or hostname.
- An organizational identity (i.e. company name) and location.
You would get a domain validated SSL certificate for one website domain.
