It would be great if it was possible to enable encryption on all exported and downloadable files. For example pst-files that are exported. The exported files could be presented in a password protected zip-file and the password displayed in the web UI for the user who initiated the export. 

The concern here is that the exported files are stored unencrypted on your systems. 

I can download the same exported file several times so the file is not removed from your systems after it has been downloaded.
