Allow to build Single Or Multi signers to generate a single signature or aggregate them
Implementations§
source§impl SignerBuilder
impl SignerBuilder
sourcepub fn new(
registered_signers: &[SignerWithStake],
protocol_parameters: &ProtocolParameters
) -> StdResult<Self>
pub fn new( registered_signers: &[SignerWithStake], protocol_parameters: &ProtocolParameters ) -> StdResult<Self>
SignerBuilder constructor.
sourcepub fn build_multi_signer(&self) -> MultiSigner
pub fn build_multi_signer(&self) -> MultiSigner
Build a MultiSigner based on the registered parties
sourcepub fn compute_aggregate_verification_key(
&self
) -> ProtocolAggregateVerificationKey
pub fn compute_aggregate_verification_key( &self ) -> ProtocolAggregateVerificationKey
Compute aggregate verification key from stake distribution
sourcepub fn build_single_signer(
&self,
signer_with_stake: SignerWithStake,
kes_secret_key_path: Option<&Path>
) -> StdResult<(SingleSigner, ProtocolInitializer)>
pub fn build_single_signer( &self, signer_with_stake: SignerWithStake, kes_secret_key_path: Option<&Path> ) -> StdResult<(SingleSigner, ProtocolInitializer)>
Build non deterministic SingleSigner and ProtocolInitializer based on the registered parties.
sourcepub fn build_test_single_signer(
&self,
signer_with_stake: SignerWithStake,
kes_secret_key_path: Option<&Path>
) -> StdResult<(SingleSigner, ProtocolInitializer)>
pub fn build_test_single_signer( &self, signer_with_stake: SignerWithStake, kes_secret_key_path: Option<&Path> ) -> StdResult<(SingleSigner, ProtocolInitializer)>
Build deterministic SingleSigner and ProtocolInitializer based on the registered parties.
Use for TEST ONLY.
sourcepub fn restore_signer_from_initializer(
&self,
party_id: PartyId,
protocol_initializer: ProtocolInitializer
) -> StdResult<SingleSigner>
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.
