This is a free and open-source file encryption solution based on the original EncFS code. Cryptonite is fully compatible with all EncFS features.

Mounting doesn't work on some Android 4.2 devices. We're working on a solution.

READ THIS FIRST: This application is UNDER DEVELOPMENT. Intended for EXPERIENCED ANDROID USERS ONLY. While most features don't require root, mounting EncFS volumes requires ROOT and Kernel FUSE support (found in some CyanogenMod ROMs). Downloading from, uploading to and creating EncFS volumes on your Dropbox or on your phone is supported on all devices.

@H: Don't use the rating system as your testing playground. It's highly demotivating.

OFFLINE MODE: To access an encrypted Dropbox volume when you're offline, sync the encrypted volume to a local folder with one of the many apps that provide online storage synchronization (e.g. FolderSync Lite or Dropsync). Then, mount that local volume with Cryptonite. This will only work on rooted phones that support FUSE though.

PERMISSIONS: Internet permission is required to access your Dropbox.

FAQ: Why can't I decrypt and encrypt files on the fly?

Why can't I mount EncFS volumes on my Samsung/ Motorola / Sony device?

Why can't I access any folder on my Dropbox?

Why do I need root privileges to mount EncFS and TrueCrypt volumes?
