Struct SignerBuilder 

Source 
pub struct SignerBuilder { /* private fields */ }
Expand description

Allow to build Single Or Multi signers to generate a single signature or aggregate them

Implementations§

Source§

impl SignerBuilder

Source

pub fn new( registered_signers: &[SignerWithStake], protocol_parameters: &ProtocolParameters, ) -> StdResult<Self>

SignerBuilder constructor.

Source

pub fn build_multi_signer(&self) -> MultiSigner

Build a MultiSigner based on the registered parties

Source

pub fn compute_aggregate_verification_key( &self, ) -> ProtocolAggregateVerificationKey

Compute aggregate verification key from stake distribution

Source

pub fn build_test_single_signer( &self, signer_with_stake: SignerWithStake, kes_signer: Option<Arc<dyn KesSigner>>, ) -> StdResult<(SingleSigner, ProtocolInitializer)>

Build deterministic SingleSigner and ProtocolInitializer based on the registered parties.

Use for TEST ONLY.

Source

pub fn restore_signer_from_initializer( &self, party_id: PartyId, protocol_initializer: ProtocolInitializer, ) -> StdResult<SingleSigner>

Restore a SingleSigner based on the registered parties and the given protocol_initializer.

This is useful since each protocol initializer holds a unique secret key that corresponds to a registration key sent to an aggregator.

The actual signing of message is done at a later epoch.

The SignerBuilder used must be tied to the key registration, stake distribution and protocol parameters of the epoch during which the given protocol initializer was created.
