Secure Sockets Layer (SSL) Certificate works through a cryptographic system between a site and a visitor’s browser. By guaranteeing that all information that passes between the two remains private and secure, SSL encryption prevents hackers from taking private data and your clients can have enhanced trust on your site. This certificate shows clients that your business is honest-to-goodness and that it is protected to conduct business with you on the web. Please note that the Domain Validation SSLs do not require any paperwork whereas you will need to furnish official documentation to the SSL Company for Organization Validation and Extended Validation SSLs.
