Functions

func BLSInit

func BLSInit()

func Generate

func Generate(sigType crypto.SigType) ([]byte, error)

Generate generates private key of given type

func RegisterSignature

func RegisterSignature(typ crypto.SigType, vs SigShim)

RegisterSignature should be only used during init

func SecpInit

func SecpInit()

func Sign

func Sign(sigType crypto.SigType, privkey []byte, msg []byte) (*crypto.Signature, error)

Sign takes in signature type, private key and message. Returns a signature for that message. Valid sigTypes are: "secp256k1" and "bls"

func ToPublic

func ToPublic(sigType crypto.SigType, pk []byte) ([]byte, error)

ToPublic converts private key to public key

func Verify

func Verify(sig *crypto.Signature, addr address.Address, msg []byte) error

Verify verifies signatures

Types

type AggregateSignature

type AggregateSignature = blst.P2Aggregate

type PublicKey

type PublicKey = blst.P1Affine

type SecretKey

type SecretKey = blst.SecretKey

type SigShim

type SigShim interface {
	GenPrivate() ([]byte, error)
	ToPublic(pk []byte) ([]byte, error)
	Sign(pk []byte, msg []byte) ([]byte, error)
	Verify(sig []byte, a address.Address, msg []byte) error
}

SigShim is used for introducing signature functions

type Signature

type Signature = blst.P2Affine
