Projects / FreeOTFE4PDA


FreeOTFE4PDA is an "on-the-fly" (OTFE) transparent disk encryption program. Using this software, you can create one or more "virtual memory cards" on your PDA. Anything written to one of these cards will be automatically and securely encrypted before being stored. A PC version is also available, allowing data encrypted on your PC to be read/written on your PDA, and vice-versa.

    Release Notes: Display layout changes were made to better support interface translations. Language translation were added for Greek and Croatian. A language translator credits dialog was added.

      Release Notes: Mount performance was optimized. Functionality was added to support language translations. Support for Linux LUKS volumes was added. XTS mode was added to Gladman cyphers (AES, MARS, RC-6, Serpent, and Twofish). RIPEMD-256 and RIPEMD-320 hash algorithms were added. An option was added to the volume creation wizard to mount new volumes after creating them. The "/create", "/noexit", and "/silent" command line options were added. A redundant message shown on dismounting volumes was removed. A fault requiring hidden volumes to begin at an offset which is a multiple of 512 bytes was corrected.

        Release Notes: A minor fault was corrected in locking protecting FreeOTFE4PDA's internal list of device handles. An option was added to enable or disable hash and cypher drivers from the user interface. By default, the SHA and AES drivers are enabled, but all others are disabled to improve performance. The driver code was refactored to allow common code to be shared between FreeOTFE and FreeOTFE Explorer (but no functional changes were made). Drivers were moved into the "DLL" subdirectory.

          Release Notes: Updated documentation. The development environment has changed to Microsoft Visual Studio 2008.

          •  29 Dec 2007 07:04

            Release Notes: The program is now available as a single .CAB file and ActiveSync installer, as well as a standard .ZIP file, making installation to a PDA even simpler. LRW and XTS cypher mode support was added. An option to revert volume file timestamps/attributes to their pre-mount values on dismounting was added. The order of cypher/hash details returned from drivers was optimized to improve time to mount on the PDA version. The LibTomCrypt-based cypher/hash drivers were updated to use LibTomCrypt v1.17. This release has been tested under Windows Mobile 6.
