The guys over at the BitTube blog have a cool post up about creating a truly cross-platform encrypted, portable drive for use on a Mac or Windows.

For those who don't know, TrueCrypt is a free, open source, encryption application.  The latest version supports the ability to make a portable drive that works cross-platform.

The BitTube guys went and did some great documentation on how to do it.  There's only one catch: they did it all without having a physical Windows machine!

They did all their creation and testing on a single Mac, and then later tested the results in a Windows VM, running on VMware Fusion.

Here are some screen caps of the results.  The first picture is of the encrypted drive mounted on the Mac:

And here's the same encrypted drive, mounted in the Windows VM, running on VMware Fusion:

Very cool stuff!  Thanks for sharing guys!  If you're interested in learning more, check it out.
