Types ¶

type BlsMultiSigner ¶

type BlsMultiSigner struct {
	singlesig.BlsSingleSigner
	Hasher hashing.Hasher
}

BlsMultiSigner provides an implements of the crypto.LowLevelSignerBLS interface

func (*BlsMultiSigner) AggregateSignatures ¶

func (bms *BlsMultiSigner) AggregateSignatures(
	suite crypto.Suite,
	signatures [][]byte,
	pubKeysSigners []crypto.PublicKey,
) ([]byte, error)

AggregateSignatures produces an aggregation of single BLS signatures over the same message

func (*BlsMultiSigner) IsInterfaceNil ¶

func (bms *BlsMultiSigner) IsInterfaceNil() bool

IsInterfaceNil returns true if there is no value under the interface

func (*BlsMultiSigner) SignShare ¶

func (bms *BlsMultiSigner) SignShare(privKey crypto.PrivateKey, message []byte) ([]byte, error)

SignShare produces a BLS signature share (single BLS signature) over a given message

func (*BlsMultiSigner) VerifyAggregatedSig ¶

func (bms *BlsMultiSigner) VerifyAggregatedSig(
	suite crypto.Suite,
	pubKeys []crypto.PublicKey,
	aggSigBytes []byte,
	msg []byte,
) error

VerifyAggregatedSig verifies if a BLS aggregated signature is valid over a given message

func (*BlsMultiSigner) VerifySigBytes ¶

func (bms *BlsMultiSigner) VerifySigBytes(_ crypto.Suite, sig []byte) error

VerifySigBytes provides an "cheap" integrity check of a signature given as a byte array It does not validate the signature over a message, only verifies that it is a signature

func (*BlsMultiSigner) VerifySigShare ¶

func (bms *BlsMultiSigner) VerifySigShare(pubKey crypto.PublicKey, message []byte, sig []byte) error

VerifySigShare verifies a BLS signature share (single BLS signature) over a given message
