Struct KeccakSpongeCols

#[repr(C)]
pub struct KeccakSpongeCols<T> {
    pub is_new_start: T,
    pub is_padding_byte: [T; 136],
    pub block_bytes: [T; 136],
    pub state_hi: [T; 68],
}

Fields

is_new_start: T

Only used on first row of a round to determine whether the state prior to absorb should be reset to all 0s. Constrained to be zero if not first round.

is_padding_byte: [T; 136]

Whether the current byte is a padding byte.

If this row represents a full input block, this should contain all 0s.

block_bytes: [T; 136]

The block being absorbed, which may contain input bytes and padding bytes.

state_hi: [T; 68]

For each of the first KECCAK_RATE_U16S u16 limbs in the state, the most significant byte of the limb. Here state is the postimage state if last round and the preimage state if first round. It can be junk if not first or last round.
