Functions

func AggregatePublicKeys

func AggregatePublicKeys(pks []types.PublicKey) (types.PublicKey, error)

AggregatePublicKeys assumes that given public keys has passed the KeyValidate() check i.e. they are not infinite and are on the right subgroup.

PublicKey objects are expected to be returned by SecretKey.PublicKey(), PublicKeyFromBytes() and AggregatePublicKeysFromBytes(), and they all should be valid. Therefore AggregatePublicKeys skips the validatity check.

func AggregatePublicKeysFromBytes

func AggregatePublicKeysFromBytes(bs [][]byte) (types.PublicKey, error)

func AggregateSignatures

func AggregateSignatures(sigs []types.Signature) (types.Signature, error)

AggregateSignatures assumes that given signatures has passed the SigValidate() check i.e. they are on the right subgroup.

Signature objects are expected to be returned by Sign(), SignatureFromBytes() and AggregateSignaturesFromBytes(), and they all should be valid. Therefore AggregateSignatures skips the validatity check.
