man losetup

EXAMPLE
       If you are using the loadable module you must have  the  module  loaded
       first with the command
 
              # insmod loop.o
 
       Maybe also encryption modules are needed.
 
              # insmod des.o # insmod cryptoloop.o
 
       The  following  commands  can  be  used as an example of using the loop
       device.
 
              # dd if=/dev/zero of=/file bs=1k count=100
              # losetup -e des /dev/loop0 /file
              Password:
              Init (up to 16 hex digits):
              # mkfs -t ext2 /dev/loop0 100
              # mount -t ext2 /dev/loop0 /mnt
               ...
              # umount /dev/loop0
              # losetup -d /dev/loop0
 
       If you are using the loadable module you may remove the module with the
       command
 
              # rmmod loop
