ruphus13 writes "While most of the US was celebrating Independence Day, the true fellow geeks over at TrueCrypt released version 6.0 of TrueCrypt over the long weekend. The new version touts two major upgrades. 'First, TrueCrypt now performs parallel encryption and decryption operations on multi-core systems, giving you a phenomenal speedup if you have more than one processor available. Second, it now has the ability to hide an entire operating system, so even if you're forced to reveal your pre-boot password to an adversary, you can give them one that boots into a plausible decoy operating system, with your hidden operating system remaining completely undetectable.' The software has been released under the 'TrueCrypt License,' which is not OSI approved."
