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