I, for one, have never been able to figure out how to use dm-crypt with 
cryptoloop files. If I had, for instance, a file and knew that if I 
started at a certain offset using a certain encryption with a certain 
key, and I wanted to mount my part of it, I have never persuaded 
dm-crypt to do that.

All proposed solutions have started  with copy or convert, neither of 
which are practical with this data.
