Implementations

impl Block

pub fn clmul(self, rhs: Self) -> (Self, Self)

Carryless multiplication.

This code is adapted from the EMP toolkit’s implementation.

pub fn hash_pt(tweak: u128, pt: &RistrettoPoint) -> Self

Hash an elliptic curve point pt and tweak tweak.

Computes the hash by computing E_{pt}(tweak), where E is AES-256.

pub fn lsb(&self) -> bool

Return the least significant bit.

pub fn set_lsb(&self) -> Block

Set the least significant bit.

pub fn flip(&self) -> Self

Flip all bits.

pub fn try_from_slice(bytes_slice: &[u8]) -> Option<Self>

Try to create a Block from a slice of bytes. The slice must have exactly 16 bytes.
