 NAME
      lofi - Loopback file driver
 
 DESCRIPTION
      The lofi file driver exports a file as a block device. Reads
      and  writes  to the block device are translated to	reads and
      writes on the underlying file. This is useful when	the  file
      contains a	file system image. Exporting it	as a block device
      through the  lofi file driver allows normal system	utilities
      to	 operate  on  the  image  through  the block device (like
      fstyp(1M)	fsck(1M),  and	mount(1M).  This  is  useful  for
      accessing	CD-ROM and FAT floppy images. See lofiadm(1M) for
      examples.
 
 
 
      File block	device entries are contained in	/dev/lofi,  while
      /dev/rlofi	 contains  the character (or raw) device entries.
      Entries are in  the  form	of   decimal  numbers  which  are
      assigned  through	lofiadm(1M).  When  created, these device
      entries are owned by root,	in group sys,  and  have  permis-
      sions  0600. While	ownership, group, and permission settings
      can be  altered,  there  are  possible  ramifications.   See
      lofiadm(1M) for more information.
 
 
+     lofi devices can be encrypted, see lofiadm(1M) for details
+     no how to specify encryption keys.
+     Since there is no header information in an lofi file the
+     encryption algorithm, keylength and key name or value are
+     not stored with or in the lofi image.

 NOTES
      Just as you would not directly access a disk device that has
      mounted  file  systems, you should	not access a file associ-
      ated with a  block	 device	 except	 through  the  lofi  file
      driver.
 
 
 
      For compatability purposes, a raw device  is  also	 exported
      along with	the block device. For example, newfs(1M) requires
      one.
