Ah. Well, looks like I wanted

sudo losetup /dev/loop0 cryptsys

Now, as I understand it, any writes or reads to or from
/dev/loop0 will be translated into the corresponding action
on cryptsys.

So then, to create an encrypted filesystem on cryptsys, I
can do

cryptsetup create cryptvol1 /dev/loop0

I've not investigated where to go from here, but that's a
start.
