This is awesome. End-to-end encryption is the natural solution to the problem of universal surveillance as well as more mundane issues, like companies losing data and servers getting hacked. I think it's very elegant that one can build useful services with untrusted servers. The algorithms for end-to-end encryption are there, but usability of actual implementations has been pretty terrible so far. For example, compare the usability of Gmail vs Thunderbird+Enigmail. Or compare the usability of Dropbox and Tarsnap. I've actually wondered why there isn't a good end-to-end encrypted Dropbox alternative that's remotely as easy to use. I hope this works out. Beautiful, usable end-to-end encrypted software is the future. See, for example, Keybase, @moxie's Signal or Whatsapp. The only caveat is that writing secure software is really hard. I just made a disk42 account, but I'll treat it as a untrusted demo until it's had more test mileage and outside code review. Also, curious: * How do you detect changes in the synced folder? * How do you do conflict resolution (if a file is edited simultaneously on two different client machines)? * What algorithms, key sizes, etc do you use for the actual encryption?
