Create volumes with keyfile as well

[Ssurgul]

Hey there. Been using the app for a few weeks, and getting it aligned with my Dropbox so I could have a secured conduit from phone to desktop and vice versa. I'm using SiriKali to grab the volume/directory/files and decrypt them. I noticed SK does support keyfiles for volumes. Would it be possible to add that function/feature into DFS to help increase decryption security?
