I'm not sure if you will need sys-fs/cryptsetup for your setup, but I
think you may have gotten confused over the difference between USE and
IUSE.  IUSE is a variable set by an ebuild to tell portage (or your PM
of choice) that this package supports certain USE flags.  See ebuild(5)
for more information.
