TrueCrypt
http://www.truecrypt.org/
Free open-source disk encryption software for
Windows XP/2000/2003 and Linux
Main Features:
Creates a virtual encrypted disk within a file and mounts it as a real
disk.
Encrypts an entire hard disk partition or a device, such as USB flash
drive.
Encryption is automatic, real-time (on-the-fly) and transparent.
Provides two levels of plausible deniability, in case an adversary forces
you to reveal the password:
1) Hidden volume (steganography – more information may be found here).
2) No TrueCrypt volume can be identified (volumes cannot be distinguished
from random data).
Encryption algorithms: AES-256, Blowfish (448-bit key), CAST5, Serpent,
Triple DES, and Twofish.
Mode of operation: LRW (CBC supported as legacy).
Based on Encryption for the Masses (E4M) 2.02a, conceived in 1997.
v4.2
April 17, 2006
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)
Improvements:
It is now possible to mount a single TrueCrypt volume from multiple
operating systems at once (for example, a volume shared over network),
provided that the volume is mounted as read-only under each system
(Windows).
Current directory is never left set to a removable device after a file
(e.g., a container, keyfile, header backup) stored on it is selected via
file selector in TrueCrypt. Therefore, it will be possible to ‘Safely
Remove’ the device in such cases. (Windows)
Improved security of set-euid mode of execution (Linux).
Other minor improvements
Bug fixes:
It is now possible to dismount volumes that cannot be opened (for example,
after disconnecting and reconnecting a USB flash drive formatted as NTFS
containing a mounted TrueCrypt volume).
Fixed bug that sometimes caused the mount process to fail under Linux when
one or more TrueCrypt volumes were already mounted.
Command line argument buffer is now wiped upon exit (Windows, command line
usage).
Other minor bug fixes
