A new OS X version of the well-known open-source disk encryption software TrueCrypt has been released. Basically, TrueCrypt creates a virtual encrypted disk that mounts in the Finder and which provides on-the-fly 256-bit encryption. This virtual disk can reside on your hard drive or a flash drive and can even be hidden. The new version relies on MacFUSE to bring its magic to the fairer platform.Unfortunately, the interface is not terribly Mac-like, through this is probably not surprising given its roots. Each virtual disk has to be created and mounted through the TrueCrypt application. Nonetheless, once mounted you can interact with the virtual disk like any other volume mounted in the Finder.
TrueCrypt is a free download from sourceforge.
Thanks to everyone who sent this in!
