ecryptfs-setup-swap(1)

NAME

   ecryptfs-setup-swap - ensure that any swap space is encrypted

SYNOPSIS

   ecryptfs-setup-swap [-f|--force]

DESCRIPTION

   This  script  will  detect  existing swap partitions or swap files, and
   encrypt them, using cryptsetup.

   Encrypted swap is essential to  securing  any  system  using  eCryptfs,
   since  decrypted file contents will exist in the system's memory, which
   may be swapped to disk at any time.  If the system swap  space  is  not
   also encrypted, it is possible that decrypted files could be written to
   disk in clear text.

   Note that most Linux distributions do not yet support resuming from  an
   encrypted   swap  space,  and  thus  hibernate/resume  will  not  work.
   Suspend/resume is unaffected.

   Upon  running  the  utility,  the  user  will  be   informed   of   the
   hibernate/resume  break,  and  asked  to  confirm  the  behavior.   The
   -f|--force option can be used to bypass this interactive prompt.
