TrueCrypt 4.3 free open-source disk encryption software has been updated with new features and Windows Vista 32 & 64 bit compatibility.
- Full compatibility with 32-bit and 64-bit Windows Vista:
- Support for User Account Control (UAC).
- All .sys and .exe files of TrueCrypt are now digitally signed with the digital certificate of the TrueCrypt Foundation, which was issued by the certification authority GlobalSign.
- When moving the mouse on a single-CPU computer while reading or writing data to a TrueCrypt volume, the mouse pointer stopped moving for a second every few seconds. This will no longer occur. (Windows Vista issue)Other minor compatibility-related changes
- TrueCrypt volume is automatically dismounted if its host device is inadvertently removed.
- Important: You should always dismount the volume in TrueCrypt and then use the "Safely Remove Hardware" function (built in Windows) before you physically remove the host device (e.g. a USB flash drive).
- Support for devices and file systems that use a sector size other than 512 bytes (e.g., new hard drives, USB flash drives, DVD-RAM, MP3 players, etc.)
- Support for devices with a GPT partition table (GUID partitions).
- After a partition is successfully encrypted, the drive letter assigned to it (if any) is automatically removed.
- Volume name (label) is displayed in device/partition selector.
- New hotkey: ‘Wipe Cache’.
- New command line switch ‘/q background’ for launching the TrueCrypt Background Task.Improvements:
- Portions of the TrueCrypt device driver redesigned.
- Maximum allowed size of FAT32 volumes increased to 2 TB (note that NTFS volumes can be larger than 2 TB).
- Traveller Disk Setup improved.
- Volumes hosted on read-only media will always be mounted in read-only mode.
- Improved support for big-endian platforms.
NOTE: I’ve yet to test this new version with Windows Vista, but previous versions worked great with Windows XP.
