Trait for some crypto methods.

Required Methods

fn hash(&self, msg: Bytes) -> Hash

Hash a message bytes.

fn sign(&self, hash: Hash) -> Result<Signature, Box<dyn Error + Send>>

Sign to the given hash by private key and return the signature if success.

fn aggregate_signatures(
    &self,
    signatures: Vec<Signature>,
    voters: Vec<Address>
) -> Result<Signature, Box<dyn Error + Send>>

Aggregate the given signatures into an aggregated signature according to the given bitmap.

fn verify_signature(
    &self,
    signature: Signature,
    hash: Hash,
    voter: Address
) -> Result<(), Box<dyn Error + Send>>

Verify a signature and return the recovered address.

fn verify_aggregated_signature(
    &self,
    aggregate_signature: Signature,
    msg_hash: Hash,
    voters: Vec<Address>
) -> Result<(), Box<dyn Error + Send>>

Verify an aggregated signature.
