How to set SSL certificate in PrestaShop
In oder to make the shopping experience for your customers more secure, you can purchase a private SSL from the SiteGround SSL Certificate page. You can enable this certificate easily via the SSL support for PrestaShop through the Admin area -> Preferences page. From this page, you can set "Enable SSL" to "Yes" which will allow the application to work with your certificate.
Please bear in mind, that the SSL connection over HTTPS is slower than the HTTP, thus the secured connection should be applied only to the pages that contain and transfer sensitive information.
