Struct ControlWord 

pub struct ControlWord(pub [u8; 8]);

An 8-byte DVB-CSA control word.

Tuple Fields

0: [u8; 8]

Implementations

impl ControlWord

pub const fn from_bytes(bytes: [u8; 8]) -> Self

Create a ControlWord from 8 bytes.

pub fn expand_block(&self) -> [u8; 56]

Expand the control word into 56 block-cipher round-key bytes.

pub fn expand_stream(&self) -> [u8; 8]

Expand to the nibble-swapped stream-cipher seed (cws).

Each byte has its high and low nibbles swapped: cws[i] = (cw[i] >> 4) | (cw[i] << 4)
