Does InterWorx support a user defined SSL certificate?
Yes. Starting with version 1.8 each SiteWorx account may have a user specified SSL certificate if the option is enabled and if the domain is on a dedicated IP and SSL functionality is enabled for the account. Self-signed, CA-signed, and chain certificates are all supported. The ability to change the main InterWorx SSL certificate to a user’s own can currently be done via the shell, but is not currently supported by the interface.
