Encrypted transfers are not possible via HTTP unless you encrypt the file itself. It might be possible via addons but for now, don't expect it. :?
Unless rejetto implements the HTTPS protocol, encrypted connections are only possible via addons etc. But certificates would cost rejetto thousands... :\ Unless it is a self-signed certificate which would not be valid for verification and will cause the browser to give you a warning everytime you load a page. Even with certificates, HTTPS requires many SSL libraries and would need a lot of work.
