ScramDisk for Linux (SD4L) is an on-the-fly encryption system
which hides complete file systems
within encrypted regular files called containers. It is a suite of
Linux tools and a
graphical user interface (GUI) which allow the creation of, and access
to ScramDisk encrypted container files.
SD4L also encrypts partitions on a hard disk or
storage media such as USB sticks or floppy disks entirely as devices.
Even complete hard disks with several
partitions can be encrypted entirely as a single container.
SD4L comprises a kernel driver scramdisk.ko (scramdisk.o for
systems with kernel 2.4.x), the
graphical user interface scramdisk and five small utilities sdcreate,
sdchange, sdmount, sdreformat and sdumount
as well as the program sdhelper which is for internal use by the kernel
- Access to ScramDisk containers generated on other platforms
- Creation of compatible ScramDisk containers
- Access to TrueCrypt containers generated on other platforms
- Creation of compatible TrueCrypt containers which can be
opened by the TrueCrypt versions which are equal or higher than the
chosen format version
- Provides privacy for sensitive data through the use of
strong encryption, which are transparently accessible via a mounted
- Includes a repair tool for damaged ScramDisk and TrueCrypt
6 and 7 containers. It is accessable by the Change button in the GUI or
- ScramDisk containers can be reformatted to TrueCrypt
containers without creating a new container and copying its contents.
The created formats are that of TrueCrypt 4 or 5
- Containers can be automatically unmounted after they have
been inactive for a period of time given on mounting the container.
Here, inactivity means that no read or write operation has taken place
on the container within this period of time
- Encrypted hard disks or containers which comprise several
partitions can be opened and the partitions will be automatically
mounted on mount directories created below a chosen directory
- A new container can be formatted as swap space and such a
container can be used for swapping out areas of the main memory
