About SSL

SSL is the summation of Secure Socket Layer. SSL certificate is a security protocol which uses encryption technique to secure your website. It secures your site in 3 ways, i.e. by encrypting browser server communication, protecting data integrity of stolen data because it cannot be decrypted, and authentication of data and website.

When an SSL certificate is installed on a website, it shows HTTPS in the URL and a padlock in the address bar.

Apart from website security, your website needs to be moved from HTTP to HTTPS to have a boost in SEO rankings as well.
