Other then emailing yourself a file or folder is there a good way
to encrypt files and folders using the DoD CAC on OS X?
You'd do this with encrypted disk images. I know the hdiutil command
is certificate and keychain aware, so it's theoretically possible--
but I've never actually tried it.
However, managing encrypted images from the command line wouldn't be
the best solution. And I don't have Leopard to play with at the moment.
Of course the side effect is bad if you lose the CAC or it expires
and gets replaced before you de-encrypt all the files or folders.
You should be able to set up an encrypted image the same way that
FileVault does--and use the same key. But it's not clear poking at
hdiutil if it supports *multiple* public key access credentials.
Note that it is possible to enable FileVault for smartcards in Leopard.
