SSL/TLS

The SSL/TLS Manager will allow you to generate SSL certificates, certificate signing requests, and private keys. These are all parts of using SSL to secure your website. SSL allows you to secure pages on your site so that information such as logins, credit card numbers, etc are sent encrypted instead of plain text. It is important to secure your site’s login areas, shopping areas, and other pages where sensitive information could be sent over the web.
