Functions

func Generate

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

Generate generates private key of given type

func GenerateFromSeed

func GenerateFromSeed(sigType crypto.SigType, seed io.Reader) ([]byte, error)

GenerateFromSeed generates private key of given type and seed

func RegisterSignature

func RegisterSignature(typ crypto.SigType, vs SigShim)

RegisterSignature should be only used during init

func Sign

func Sign(msg []byte, privkey []byte, sigType SigType) (*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

func VerifyAggregate

func VerifyAggregate(pubKeys, msgs [][]byte, signature []byte) error

Types

type SigShim

type SigShim interface {
	GenPrivate() ([]byte, error)
	GenPrivateFromSeed(seed io.Reader) ([]byte, error)
	ToPublic(pk []byte) ([]byte, error)
	Sign(pk []byte, msg []byte) ([]byte, error)
	Verify(sig []byte, a address.Address, msg []byte) error
	VerifyAggregate(pubKeys, msgs [][]byte, signature []byte) bool
}

SigShim is used for introducing signature functions

type SigType

type SigType = crypto.SigType

type Signature

type Signature = crypto.Signature
