Scramdisk was a freeware on-the-fly encryption program for Windows 95, Windows 98, and Windows Me, created by Shaun Hollingworth in the late 1990s.[1] A non-free version was also available for Windows NT. Scramdisk containers appeared filled with random data rather than the actual content, supporting plausible deniability.[2]

The last stable Windows release was version 3.01r3c.[2] The software is no longer maintained. Hollingworth later collaborated with Paul Le Roux, the author of Encryption for the Masses (E4M), to produce a commercial successor, DriveCrypt, under the German security company SecurStar.[3][4] Hollingworth contributed a driver for Windows 9x, while Le Roux provided a driver for Windows NT.[4]

Scramdisk 4 Linux (SD4L) is a separate open-source project that provides access to Scramdisk and TrueCrypt containers on Linux.[2]

Licensing

Although Scramdisk's source code is available, it was licensed only for private study and not for further development or redistribution.

Scramdisk contains an implementation of the MISTY1 encryption algorithm written by Hironobu Suzuki (known online as H2NP) and released under the GNU General Public License version 2. Because Scramdisk's source-viewing license is incompatible with the GPL, the software is in violation of the GPL.[5]
