Cryptonite

Cryptonite


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.

SECURITY: Read up on important security considerations: http://code.google.com/p/cryptonite/wiki/SecurityConsiderations

PERMISSIONS: Internet permission is required to access your Dropbox.
SD card access is required to read and write files.

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?

Too inconvenient This app was released well over a year ago yet is still a beta product, it has barely any options for customisation and doesn't provide standard features like multi-select and thumbnail view so you have to move files one by one into the encfs. It also makes it obvious that the folder is encrypted due to the encfs6 file which stands out like a sore thumb, worse still it significantly decreases image quality when encrypted.

Good App But Need Some Modification Really ,its a good encrption app, the main key is, it is open source. It need Some Update about its File managing system, It have a bug, that some time it doest forget the encryption properly, so when you check App file you found the encryption file there, so its very risky, file also need to be un-restoreable. mean after deleting the file, the make a fake file at that location so traces of previous files will be removed.

Great app but critical feature is faulty Hi, this app's concept is fantastic, it provides encFS (boxcryptor) support for files I have separately synced from the cloud to my android device. The one very big sore point is that mounting just doesn't work for me. The only way to use the app is with the decrypt local folder option, which essentially decrypts just one file at a time. This is extremely limiting. I'm using a nexus 5. I tried it stock rooted, stock rooted with franco kernel, and the latest cyanogenmod 11 nightlies. I got different weird error messages depending on which iteration I tried. Some said the mount point was not empty (it was), others said the destination directory was not found (it was correct). I even tried mounting through and elevated adb shell. No errors reported from the encfs binary, but still nothing was mounted. It takes a lot of effort for us simple non-expert users to research all this stuff to try to come up with a working solution. I think the author should do some of this research for us, for example keeping an updated and comprehensive FAQ. Perhaps specify which kernels work with which devices. Again, a great concept and interface, but the best feature doesn't work
