      Block device level encryption mainly through the use

      \textbf{cryptsetup} can also use:

         \item
         \textbf{plain dm-crypt} volumes
         \item
         \textbf{loop-AES}

         \textbf{TrueCrypt}-compatible format

      \item
      However, \textbf{LUKS} is the method most often used
      in \textbf{Linux}.

      \item
      Easy to migrate partitions to other disks or systems.
      \item
      Can be used to transparently encrypt \textbf{swap}
      partitions.

\cprotect\note{

   Modern \textbf{Linux} distributions provide block device
   level encryption mainly through the use of \textbf{LUKS}
   (\textbf{L}inux \textbf{U}nified \textbf{K}ey
   \textbf{S}etup).  Using block device encryption is highly
   recommended for portable systems such as laptops,
   tablets, and smart phones.

   \textbf{LUKS} is installed on top of \textbf{cryptsetup},
   a powerful utility that can also use other methods such
   as \textbf{plain dm-crypt} volumes, \textbf{loop-AES} and
   \textbf{TrueCrypt}-compatible format.  We will not discuss
   these alternatives, as \textbf{LUKS} (which was
   originally designed for \textbf{Linux} but has also been
   exported to other operating systems) is the standard
   method most often used in \textbf{Linux}.

   The \textbf{dm-crypt} kernel module uses the
   \textbf{device mapper} kernel infrastructure that is also
   heavily used by \textbf{LVM}, which we discussed
   previously.

   Because \textbf{LUKS} stores all necessary information in
   the partition header itself, it is rather easy to migrate
   partitions to other disks or systems.

   \textbf{LUKS} can also be used to transparently encrypt
   swap partitions.  }
