1. Connect with Dropbox

In order to use BoxCryptor for Android, you have to connect it with your Dropbox and choose the source folder with your encrypted files. Click the “Connect with Dropbox” button at the main screen and enter your Dropbox account information.

Important: These credentials are never stored (not even locally on the device) and never sent anywhere else except to the Dropbox server in order to get an authentication token which is then stored on the device.

2. Select your source folder

Browse to the source folder in your Dropbox which contains the encrypted files (e.g. DropboxBoxCryptor). BoxCryptor for Android automatically detects if a folder is a valid source folder and then asks you for the password which was used to encrypt the files. When you successfully selected your source folder, the password is stored on your device and the next time you open BoxCryptor for Android directly opens your encrypted folder.

3. Browse and view your encrypted files

You can now browse and view your encrypted files just like you know it from the native Dropbox App. When you open a file by tapping it, BoxCryptor for Android downloads the encrypted file, decrypts it on your device and opens it with the appropriate application on your device. Available actions in the menu are:

  • Refresh: Refresh the current view
  • Preferences: Opens the preferences menu (see below)
  • Exit: Exits the BoxCryptor app

4. Preferences and App unlock

In the preferences menu you can manage the settings of BoxCryptor for Android, e.g. unlink from your Dropbox account or choose a different source folder. You can also enable or dislable the App Unlock feature. If you have App Unlock enabled, every time you open the BoxCryptor app, you have to enter a numeric PIN in order to unlock the app. Available preferences are:

  • Unlink device from Dropbox: The stored Dropbox authentication token will be deleted and BoxCryptor for Android will no longer be linked to your Dropbox account.
  • Change source folder: If you have multiple encrypted source folders in your Dropbox, this menu item lets you change the source folder
  • Clear stored password: Deletes the stored password for the current source folder. At the next start of BoxCryptor for Android, you have to enter the password again.
  • App Unlock: Require a numeric PIN to unlock app every time it is opened.

    EncFS 1.7.4 installer for Mac OS X available

    UPDATE 05/07/2012:
    We have released a first beta of BoxCryptor for Mac OS X! You can find more information in our forums.

    We have received a lot of feedback that installing and compiling EncFS on Mac OS X is too complicated. Although we’re not the developers of EncFS, we decided to create and provide a very easy, “one-click” installer for the latest EncFS version on Mac OS X. The installer contains the following packages:

    • MacFUSE v2.0.3.2 for Leopard and Snow Leopard
    • MacFUSE v2.2.2.0 for Lion
    • MacFusion v2.0.4
    • EncFS Plugin for MacFusion v0.2
    • EncFS v1.7.4

    As MacFUSE is not maintained anymore and the latest official MacFUSE version does not work with Mac OS X Lion, our Lion installer contains a community build by Bryan Pham (see Google Groups) who patched the Tuxera MacFUSE build 2.2.1 so that it works well with Lion. In our tests, his MacFUSE build worked like a charm and we did not encounter any problems. However, be advised, that his version is not officially supported. So how does it work?

    1. Download our installer

    Download the appropriate version of our installer for EncFS from our webserver:

    2. Install EncFS

    Execute the installer package from the downloaded .dmg file and follow the instructions.

    3. Mount the encrypted folder in MacFusion

    Start MacFusion and configure it to mount the encrypted BoxCryptor folder. Click on the “Plus”-sign in the left bottom corner and select EncFS. Choose the folder encrypted by BoxCryptor (e.g. ~/Dropbox/BoxCryptor) as EncFS Raw Path and enter the correct password. Now switch to the Macfusion tab, choose a Mount Point (e.g. ~/BoxCryptor), a Volume Name and click “OK”.

    Now, press the “Mount” button and allow keychain access!

    6. That’s it! You can now encrypt and decrypt files from BoxCryptor with EncFS on Mac OS X! Happy (secure) syncin’ with Dropbox and all the other cloud storage services like iCloud/MobileMe or SugarSync!
