Automatically sync files via secure, distributed technology.
This works like existing cloud file storage systems such as dropbox, box.com etc, except that:
File transfers are encrypted and use the Bittorrent protocol. Your information is never stored on a server in the cloud and your data is protected by private keys. This means that no-one but you can access it.
BitTorrent Sync was designed with privacy and security in mind. All the traffic between devices is encrypted with AES cypher and a 256-bit key created on the base of the secret—a random string (20 bytes or more) that is unique for every folder.
