Key used for encryption. It is encoded as a hexadecimal number.
You can only use key sizes that are valid for the selected cipher.
- Multi-key compatibility mode. You can define <keycount> keys and
- then sectors are encrypted according to their offsets (sector 0 uses key0;
- sector 1 uses key1 etc.). <keycount> must be a power of two.
The IV offset is a sector count that is added to the sector number
before creating the IV.
