Functions

func FlattenECPoints

func FlattenECPoints(in []*ECPoint) ([]*big.Int, error)

func GenerateNTildei

func GenerateNTildei(safePrimes [2]*big.Int) (NTildei, h1i, h2i *big.Int, err error)

Types

type ECPoint

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

ECPoint convenience helper

func NewECPoint

func NewECPoint(curve elliptic.Curve, X, Y *big.Int) (*ECPoint, error)

Creates a new ECPoint and checks that the given coordinates are on the elliptic curve.

func NewECPointNoCurveCheck

func NewECPointNoCurveCheck(curve elliptic.Curve, X, Y *big.Int) *ECPoint

Creates a new ECPoint without checking that the coordinates are on the elliptic curve. Only use this function when you are completely sure that the point is already on the curve.

func ScalarBaseMult

func ScalarBaseMult(curve elliptic.Curve, k *big.Int) *ECPoint

func UnFlattenECPoints

func UnFlattenECPoints(curve elliptic.Curve, in []*big.Int, noCurveCheck ...bool) ([]*ECPoint, error)

func (*ECPoint) Add

func (p *ECPoint) Add(p1 *ECPoint) (*ECPoint, error)

func (*ECPoint) Curve added in v1.3.3

func (p *ECPoint) Curve() elliptic.Curve

func (*ECPoint) EightInvEight added in v1.3.3

func (p *ECPoint) EightInvEight() *ECPoint

func (*ECPoint) Equals

func (p *ECPoint) Equals(p2 *ECPoint) bool

func (*ECPoint) GobDecode

func (p *ECPoint) GobDecode(buf []byte) error

func (*ECPoint) GobEncode

func (p *ECPoint) GobEncode() ([]byte, error)

func (*ECPoint) IsOnCurve

func (p *ECPoint) IsOnCurve() bool

func (*ECPoint) MarshalJSON

func (p *ECPoint) MarshalJSON() ([]byte, error)

crypto.ECPoint is not inherently json marshal-able

func (*ECPoint) ScalarMult

func (*ECPoint) SetCurve

func (p *ECPoint) SetCurve(curve elliptic.Curve) *ECPoint

func (*ECPoint) UnmarshalJSON

func (p *ECPoint) UnmarshalJSON(payload []byte) error

func (*ECPoint) ValidateBasic

func (p *ECPoint) ValidateBasic() bool

func (*ECPoint) X

func (p *ECPoint) X() *big.Int

func (*ECPoint) Y

func (p *ECPoint) Y() *big.Int
