11 cryptsetup-fvault2Dump - dump the header information of a FVAULT2 (FileVault2 compatible) device
15 *cryptsetup _fvault2Dump_ [<options>] <device>*
19 Dump the header information of a FVAULT2 (FileVault2 compatible) device.
21 If the --dump-volume-key option is used, the FVAULT2 device volume key
22 is dumped instead of header information. You have to provide password
23 or keyfile to dump volume key.
25 Beware that the volume key can be used to decrypt the data stored in
26 the container without a passphrase.
27 This means that if the volume key is compromised, the whole device has
28 to be erased to prevent further access. Use this option carefully.
30 *<options>* can be [--dump-volume-key, --volume-key-file, --key-file,
31 --keyfile-offset, --keyfile-size, --timeout].
