Enctrypted file uploads to a server

[wysota]

I considered using Qftp and tunneling FTP over SSH, but my users are very non-technical, and I don't know of any way to tunnel FTP over SSH without requiring the user to manually make the SSH connection. I'm not going to be able to push a solution that requires retraining of the users.

You can use stunnel (http://stunnel.mirt.net/) through QProcess to set up an SSL connection to your server. Your users won't have to touch a thing and you'll have a decent secure connection with only a light dependency.

I was looking at that earlier today, but according to the FAQ it won't work with FTP:

This is not entirely true (it would require a special FTP server), but still you don't have to use FTP itself, right? There is a service FTPS which is FTP over SSL but you can also use your custom protocol, HTTP or whatever else you want that uses a single port to communicate.
