Miscellaneous Notes

  • Please, do read the documentation (the FAQ section, in particular) before emailing questions! The FAQ section in particular may well have the answer you're looking for.
  • Both the PDA and PC versions of FreeOTFE are fully compatible with one another.
  • From the main window, doubleclicking on a mounted drive will launch explorer on that drive. Rightclicking brings up a context menu.
  • After creating a new FreeOTFE volume it is recommended that you make a backup of the volume's CDB.
    • In the case of volume files which have their CDB stored as part of the volume file, this can be achieved by selecting "Tools | Critical data block | Backup..."
    • In the case of volume files where the CDB is stored in a separate keyfile, simply make a backup copy of this keyfile.
  • A number of FreeOTFE volume properties can be changed via the "Tools | Change volume/keyfile password/details..." menuitem. Note that volumes must be dismounted first before they can be modified in this way.
  • An option is included to dump out a human readable version of the volume's critical data block/keyfile's contents (select "Tools | Critical data block | Dump to human readable file..."). This option is primarily intended to assist developers, and to future-proof volumes file by giving you access to the actual master encryption/decryption key used by the volume it dumps out. It should be noted that the inclusion of this option does not present a security risk as it requires that the user to enter the volume/keyfile's password immediately before it can operate (obviously, the volume/keyfile's password is needed in order to decrypt the critical data block). If an attacker has your volume/keyfile's password, clearly this option will give no further information away.
  • Both the PC and PDA versions have a "Revert timestamps" option. If selected, then when mounting a volume file, its timestamps will be noted. When the volume is subsequently dismounted, these timestamps will be restored. By default, the PC version has this option switched on, and the PDA version has it switched off. If you are going to use both the PC and PDA version with the same volume file, syncing between the two, it is recommended that this option is turned off on both your PC and PDA installations, in order for ActiveSync to recognise when your volume has been modified.
