Encrypting Removable Mac Drive

Posted by Dan Gillmor

In this recent posting I was bemoaning the missing encryption software in a
nifty device I've been testing, a USB-powered flash-memory "disk drive" for
my Mac. The package comes with crypto for Windows, but not for the Mac.

Several readers, including an Apple employee, pointed out an elegant and
remarkably easy-to-use solution. Here's what he said:

I wouldn't trust my sensitive data to commercial encryption either. What
you CAN do is create an encrypted disk image using the OS X Disk Copy
utility.

Applications/Utilities/Disk Copy; then

Image/New Blank Image

Select the size of whatever your diskonkey is, and select 128bit AES
(Advanced Encryption Standard) with a complex passphrase that you can add
to your keychain.

Keep that disk image file on your diskonkey, now, if something ever
happened, one would have to be able to break US Government approved 128bit
AES.

A little more elegant than the Windows solution...;-]
