Struct entropy_protocol::KeyShare

pub struct KeyShare<P>
where
    P: SchemeParams,
{ /* private fields */ }

The full key share with auxiliary parameters.

Implementations

impl<P> KeyShare<P>

where P: SchemeParams,

pub fn new_centralized( rng: &mut impl CryptoRngCore, num_parties: usize, signing_key: Option<&SigningKey<Secp256k1>>, ) -> Box<[KeyShare<P>]>

Returns num_parties of random self-consistent key shares (which in a decentralized case would be the output of KeyGen + Auxiliary protocols).

pub fn update(self, change: KeyShareChange<P>) -> KeyShare<P>

Return the updated key share using the share change obtained from the KeyRefresh+Auxiliary protocol).

pub fn verifying_key(&self) -> VerifyingKey<Secp256k1>

Return the verifying key to which this set of shares corresponds.

pub fn num_parties(&self) -> usize

Returns the number of parties in this set of shares.

pub fn party_index(&self) -> usize

Returns the index of this share’s party.
