Keybase Releases Encrypted File-Sharing iPhone App

Keybase last week announced the alpha release of the Keybase app for the iPhone with a cryptographically secure file mount. Users can write data in an automatically created folder in this format: /keybase/public/username. Files written in the folder are signed automatically and appear as plain text files on computers. The folder prevents server-side and man-in-the-middle attacks, according to Keybase. Files stream in on demand; there is no syncing as there is in Dropbox, Google Drive and Box.
