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.  Sus‐
       pend/resume is unaffected.

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