If you don't want to purchase your own SSL certificate, you may use the Scarlet's Web Shared SSL. This is a free SSL. The Shared SSL carries all the same levels of encryption and security that a Private SSL carries but there is a big difference. To use your SSL certificate you would point your hyperlinks that you want to be secure to https://rona.scarletsweb.com/~yourusername. When your customers look at the URL or examine the validity of the Shared Certificate they will see that it belongs to Scarlet's Web instead of to your specific site. Some customers may be leery of this. For the sake of professionalism, it's best to purchase a Private SSL.
Note:Â You cannot use the shared SSL Certificate if you have purchased a dedicated IP, only when you are on the shared IP.
