Functions

func ActSigType 

func ActSigType(typ string) crypto.SigType

func AddressSigType 

func AddressSigType(addr address.Address) crypto.SigType

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"

Types

type Key 

type Key struct {
	KeyInfo

	PublicKey []byte
	Address   address.Address
}

func DecodePricateKey 

func DecodePricateKey(k string) (*Key, error)

DecodePricateKey Decode the private key exported: eg:7b22...227d

type KeyInfo 

type KeyInfo struct {
	Type       string // secp256k1 or bls
	PrivateKey []byte
}

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
}
