Nobody stops people to use a stackable encrypted filesystem such as EncFS or eCryptfs over Dropbox.
I have never tried, and don't know, but does Dropbox deal elegantly with encrypted filesystems? If I have a 1GB encrypted volume sitting in my dropbox folder, and I save a change to a 1KB text doc in it, what does dropbox transmit?
My suspicion is that they transmit the entire 1GB file (falling ever behind each time I do a save in it). They don't do low level file hooks, to my knowledge, and there's no way they're doing large scale binary diff'ing.
- qznc 14y agoEncfs encrypts each file on its own. It also encrypts the name. So if you edit your 1KB "passwords.txt" file, Dropbox sees an updated 1KB "mOvTBivPznAWPrQSuflgVXFJ" file.
- huggyface 14y agoAhh okay that makes sense. Very nice then. I was thinking more of the Truecrypt variety, but Encfs sounds ideal (albeit not really a file system).
- patdennis 14y agoI use truecrypt in Dropbox. If you make a small change to anything in a (potentially large) truecrypt volume, it has to re-sync the whole volume.
- 1SaltwaterC 14y agoThe issue with TC is the fact that it doesn't resync the volume while it's mounted.
