Free open-source disk encryption software for Windows Vista/XP/2000 and Linux
Features:
- Creates a virtual encrypted disk within a file and mounts it as a real disk.
- Encrypts an entire hard disk partition or a storage 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, Serpent, and Twofish. Mode of operation: LRW.
Changelog:
- Improvements:
- Full support for custom screen DPI settings. (Windows, GUI)
- Other minor improvements. (Windows and Linu
- Bug fixes:
- Fixed bug that in some cases caused the "Safely Remove Hardware" function to fail.
- In Windows Vista, it is now possible to read data from file-hosted TrueCrypt volumes located on UDF-formatted media mounted in read-only mode.
- All Volume Creation Wizard GUI elements are now correctly displayed on systems with custom DPI settings. (Windows, GUI)
- Other minor bug fixes. (Windows and Linu
- Security improvements:
- Linux: When running without administrator privileges, TrueCrypt automatically attempts to elevate its access rights (if necessary) using the sudo command. The Linux version of TrueCrypt no longer supports the set-euid root mode of execution. These changes also prevent all discovered and undiscovered (if any) security issues related to the set-euid root mode of execution, including an issue affecting all previous Linux versions of TrueCrypt where a local non-administrator user could cause a denial of service or gain administrator privileges.
- Miscellaneous:
- If dismount is forced on a TrueCrypt volume when TrueCrypt runs in traveller mode, the TrueCrypt driver will not be unloaded when TrueCrypt exits (it will be unloaded only when the system is restarted or shut down). This prevents various problems caused by a bug in Windows (for instance, it would be impossible to start TrueCrypt again as long as there are applications using the dismounted volume). (Windows)
