TrueCrypt 4.2 Released

New version of the TrueCrypt was released yesterday. I have been using TrueCrypt for some time and really recommend it if you need on-the-fly encryption protection for portable files.

New Features:

• TrueCrypt volumes can now be created under Linux.
• Ability to create a ‘dynamic’ container whose physical size (actual disk space used) grows as new data is added to it. (Dynamic containers are pre-allocated NTFS sparse files).
• Volume passwords/keyfiles can be changed under Linux.
• Keyfiles can be created under Linux.
• Volume headers can be backed up and restored under Linux.
• Multiple keyfiles can be selected in the file selector by holding the Control (Ctrl) or Shift key (Windows).
• It is now possible to enable and directly set keyfiles by dragging the icon of keyfile(s) or of keyfile search path(s) to the password entry window (Windows only).
• New Linux command line option: -u, --user-mount, which can be used to set default user and group ID of the file system being mounted to the user and group ID of the parent process. Some file systems (such as FAT) do not support user permissions and, therefore, it is necessary to supply a default user and group ID to the system when mounting such file systems.
• The build.sh script can now perform automatic configuration of the Linux kernel source code, which is necessary in order to compile TrueCrypt on Linux. Note that this works only if the installed version of the kernel enables/supports it.
• TrueCrypt volume properties can be viewed under Linux.
• New Mount Option: 'system'. It is possible to place paging (swap) files on a TrueCrypt volume that is mounted with this option enabled. Thus, it is possible to use TrueCrypt to on-the-fly encrypt a paging file. (Windows, command line usage)
• New Mount Option: 'persistent'. A volume mounted with this option enabled is not displayed in the TrueCrypt GUI and is prevented from being auto-dismounted (‘Dismount All’ will not dismount the volume either). (Windows, command line usage)
