56 in combination with the selected iv mode.
57 Note that for some iv modes the key string can contain additional
58 keys (for example IV seed) so the key contains more parts concatenated
82 The IV offset is a sector count that is added to the sector number
83 before creating the IV.
142 The <type> can be "none" if metadata is used only for persistent IV.
147 used for storing authentication tag (and persistent IV if needed).
