SYNOPSIS

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

DESCRIPTION

14       This  script  will  detect  existing swap partitions or swap files, and
15       encrypt them, using cryptsetup.
16
17       Encrypted swap is essential to  securing  any  system  using  eCryptfs,
18       since  decrypted file contents will exist in the system's memory, which
19       may be swapped to disk at any time.  If the system swap  space  is  not
20       also encrypted, it is possible that decrypted files could be written to
21       disk in clear text.
22
23       Note that most Linux distributions do not yet support resuming from  an
24       encrypted  swap  space,  and thus hibernate/resume will not work.  Sus‐
25       pend/resume is unaffected.
26
27       Upon running the utility, the user  will  be  informed  of  the  hiber‐
28       nate/resume  break,  and asked to confirm the behavior.  The -f|--force
29       option can be used to bypass this interactive prompt.
