luksDump <device>

              Dump the header information of a LUKS device.

              If  the --dump-master-key option is used, the LUKS device master key is dumped instead of the keyslot info. Together with --master-key-file option, master key is dumped to a file instead of
              standard output. Beware that the master key cannot be changed without reencryption and can be used to decrypt the data stored in the LUKS container without a passphrase and even without the
              LUKS header. This means that if the master key is compromised, the whole device has to be erased to prevent further access. Use this option carefully.

              To dump the master key, a passphrase has to be supplied, either interactively or via --key-file.

              <options> can be [--dump-master-key, --key-file, --keyfile-offset, --keyfile-size, --header, --disable-locks, --master-key-file, --type].

              WARNING: If --dump-master-key is used with --key-file and the argument to --key-file is '-', no validation question will be asked and no warning given.
