How to mount an AES-encrypted .DMG file containing a FAT12 filesystem?

My question says it all: on Ubuntu, is there any way to mount a .dmg file (as produced by OS X's Disk Utility) that contains an AES-encrypted, FAT12 filesystem?

I've seen sporadic advice about how to mount .dmg files containing hfsplus filesystems, so I'd have thought the fat12 (aka, "msdos") filesystem would be even easier. The closest I've come is:

mount -oloop,encryption=aes-256 -t msdos privatedmg.dmg ~/mounted

But this gives me the error ioctl: LOOP_SET_STATUS: Invalid argument. I don't know much about linux filesystem mechanics, but am eager to learn!

emm what's coming to my mind I can help you this way only:

If it's possible or if you're willing converting .dmg to .img hfsplus open a Terminal Ctrl + Alt +T and type:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install dmg2img

then install mountable manager, I use AcetoneISO:

sudo apt-get install acetoneiso

or Mountmanager:

sudo apt-get install mountmanager

firstly try to mount .dmg using one of these packages, if no access you can still use converting tool mentioned above.
