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

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

       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 hiber-
       nate/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.
