Types

type FixedKSigner

type FixedKSigner struct {
	// contains filtered or unexported fields
}

FixedKSigner is a ethereum ECDSA signer who always sign payload with the given K value. In theory K value is randomly selected in ECDSA algorithm's step 3: https://en.wikipedia.org/wiki/Elliptic_Curve_Digital_Signature_Algorithm, but here we use a fixed K value instead.

func NewFixedKSigner

func NewFixedKSigner(privKey string) (*FixedKSigner, error)

func (*FixedKSigner) SignWithK

func (s *FixedKSigner) SignWithK(k *secp256k1.ModNScalar) func(hash []byte) ([]byte, bool)

SignWithK signs the given hash using fixed K.
