Last month the TrueCrypt Foundation released TrueCrypt 5.0, which finally introduces a Linux GUI for the cross-platform encryption application. TrueCrypt 5.0's numerous other enhancements include a Mac OS X port, XTS operation mode, the ability to encrypt a system partition or drive under Windows, and the addition of the SHA-512 hash algorithm.
The binary downloads for Linux used to be tailored specifically to each different Linux distribution version, but are now reduced to just two: openSUSE (x86) and Ubuntu (x86). The new TrueCrypt design is no longer affected by upgrades and updates to the Linux kernel. That's good news for users of other distributions as well, who must still manually compile TrueCrypt from source, but won't need to do so after every kernel change.
