About ShuffleStacks
Shufflecake is a Linux tool for creating multiple hidden encrypted volumes on a storage device to support plausible deniability. Each volume is encrypted with a different password-derived key and stored across empty space so it looks like random noise when closed. A device can hold up to 15 volumes in a hierarchy, where a password for a less-hidden decoy volume can be shared while more-hidden volumes remain undetected. Opened volumes appear as virtual block devices that can be partitioned, formatted with a filesystem of choice, and mounted.
The project states the software is still experimental and should not be relied on for important security needs. Initializing a device overwrites it with random data, and use requires loading a Linux kernel module. It has been tested only on Debian/Ubuntu and similar derivatives.
Key features
- Create up to 15 hidden volumes per initialized device
- Encrypt each volume with separate password-derived key
- Open less-hidden volumes recursively with one password
- Use volumes as virtual block devices for formatting and mounting
- Initialize USB sticks, discs, partitions, or file-backed loop devices
- Close device and all open volumes with single command
Best for: Linux users who need hidden volumes with plausible deniability, such as whistleblowers, journalists, and activists facing coercion.
Good for
- Hidden volumes are indistinguishable from random noise when not decrypted
- Supports formatting each volume with any filesystem of choice
- Source code is released under GNU General Public License v2.0 or later
Watch out for
- Described as experimental with warning not to rely on it for important use
- Tested only on Debian/Ubuntu and similar derivatives
- Initializing a device overwrites it with random data

ShuffleStacks FAQ
How many hidden volumes can a device hold?
Up to 15. During initialization the user chooses N between 1 and 15 and provides N passwords ordered from less hidden to more hidden.
What happens when I open a volume with one password?
It unlocks that slot and automatically opens less-hidden volumes recursively. They appear as virtual block devices that can be formatted, mounted, and used concurrently.
What is needed to run Shufflecake?
A Linux system with the dm_sflc kernel module loaded before using the sflc command-line tool and libsflc library.
