Finally we have a truly portable, open source, encrypted filesystem. I’ve tested a fair share of encrypted filesystem solutions. The most promising probably being encfs since it could be used with Fuse, but that only works on OS X and Linux at best.

TrueCrypt, probably the best solution available, was only working on Linux and Windows… up to now.

Some dude got impatient for the OS X port, managed to make a deal with a developper to code it for 1500$, raised those 1500$ and BAM! Bob’s you’re uncle.

The software is labelled alpha, described as beta, and used in production… w00t. Jokes aside, it’s been released for a few weeks now and no serious data-destroying bug stories have arose. Nevertheless, you might want to backup to another more trusted encrypted disk somewhere, every now and then.

Bare in mind the TrueCrypt team annouce their 5.0 release for the 4th of Febuary 2008 (that’s in 2 days) and claim OS X support. Watch this space…

Still interested? Download the software here:

• TrueCrypt for OS X
• TrueCrypt for Linux and Windows

OS X notes:

• Your encrypted filesystem image should have a .img extension.
• When mounting a hidden volume, you’ll be asked the outer volume password, then the hidden volume password.
• Unmounting in finder does not dismount the image. It’s a known bug. Use ocutil -detach.
