Methods

impl Keys

pub fn phase1_create(index: usize) -> Keys

Phase 1 Each player selects a random Scalar and computes its assoicated "Public Point" basically raised to the group basepoint
This is a keypair

pub fn phase1_broadcast(&self) -> (KeyGenBroadcastMessage1, Scalar)

Phase 1.1 Each Player samples a random nonce Scalar to produce a commitment to the PublicPoint and shares this hash based commitement with the other players.
