*** Note: Your device MUST be *ROOTED* for this work. It will not work on non-rooted devices! ***
LUKS Manager provides on-the-fly encryption (AES by default) to virtual folders on Android devices.
These virtual folders can be dynamically mounted, unmounted, created and deleted as needed. Similar to Truecrypt in functionality.
Note: Truecrypt and LUKS Manager volumes are not cross-compatible.
Note: Maximum volume size is limited by the filesystem it is created on. Most SD Cards are formatted as FAT32 and FAT32 only supports file sizes up to 4GB. This is a limitation of the filesystem not LUKS Manager. If you want volumes larger than 4GB you must create the volume on an EXT2/4 partition.

The Android device must:
* Be rooted *
* Have a kernel that supports secure dm-crypt modes (CONFIG_DM_CRYPT) and loopback devices
* Have BusyBox installed
* Have SuperUser installed
Most stock kernels do NOT work!
This package contains:
* A statically compiled and stripped version of cryptsetup for the ARM7 using the tools provided by The Guardian Project.
* A statically compiled and stripped version of mkdosfs from dosfstools package for the ARM7.
* A bash shell script called "luks" that does volume management.
* A native java app that provides a GUI interface to the luks script and a basic file explorer.
Fixed lockup when creating volumes with FAT support disabled.
Fixed text editor menu ordering.
Added support for Samsung preferences path.
Fixed false volume notifications on non-rooted phones.
Notification fixes when volumes are created, mounted and removed.
Removed time stamp on volume mount notifications.
Set minimum volume size to 3MB in luks script.
Improved volume unmount reporting.
Symbolic links to devices may be used as containers.
Modified the cut command to work with more versions of busybox.
Fixed a bug dealing with volume removal when launching the luks script manually.
Rewrote code sections due to moderate source corruption. *sigh*
About text changes and updates.
Major rewrite to the luks shell script and GUI app to support user defined volume locations.
Encryption cipher and keysize are now user definable. (kernel support required)
Moved storage of volume information:
Prompts to upgrade if loop device files are found in SDCard .data directory.
Removed top level restriction on file explorer activity.
Default file system changed from EXT4 to EXT2.
FAT file system support now enabled by default.
Added volume mount and unmount desktop shortcuts.
Added notification when volumes are mounted. (Can be toggled off in preferences)
Added landscape support to the main and volume edit activities.
Added basic SDcard support to install binaries routine.
(Fixes java.lang.NullPointerException on binary install.)
Added toggle to disable binary hash checks on startup. This enables customized luks scripts and/or binaries.
Small fix to application initialization. (hopefully fixes odd reboot issue on some devices)
Attempts to unmount volumes on ACTION_SHUTDOWN and MEDIA_EJECT broadcasts.
Additional checks and error handling if no volumes exist.
Additional error handling in luks script during volume mounting and creation.
Added required BusyBox applet checks on startup.
About Dialog additions / changes.
Small text changes (formatting and typo fixes).
Recompiled lm.cryptsetup binary under android-ndk-r6b.
Hopefully this will stop segfaults on various devices.
