Types

type BitCurve 

type BitCurve struct {
	P       *big.Int // the order of the underlying field
	N       *big.Int // the order of the base point
	B       *big.Int // the constant of the BitCurve equation
	Gx, Gy  *big.Int // (x,y) of the base point
	BitSize int      // the size of the underlying field
}

A BitCurve represents a Koblitz Curve with a=0. See http://www.hyperelliptic.org/EFD/g1p/auto-shortw.html

func (BitCurve *BitCurve) Double(x1, y1 *big.Int) (*big.Int, *big.Int)

Double returns 2*(x,y)

func (*BitCurve) GenerateKey 

func (BitCurve *BitCurve) GenerateKey(rand io.Reader) (priv []byte, x, y *big.Int, err error)

TODO: double check if it is okay GenerateKey returns a public/private key pair. The private key is generated using the given reader, which must return random data.

func (*BitCurve) IsOnCurve 

func (BitCurve *BitCurve) IsOnCurve(x, y *big.Int) bool

IsOnBitCurve returns true if the given (x,y) lies on the BitCurve.

func (*BitCurve) Marshal

Marshal converts a point into the form specified in section 4.3.6 of ANSI X9.62.

func (*BitCurve) Params 

func (BitCurve *BitCurve) Params() *elliptic.CurveParams

func (*BitCurve) ScalarBaseMult 

func (BitCurve *BitCurve) ScalarBaseMult(k []byte) (*big.Int, *big.Int)

ScalarBaseMult returns k*G, where G is the base point of the group and k is an integer in big-endian form.

func (*BitCurve) ScalarMult 

func (BitCurve *BitCurve) ScalarMult(Bx, By *big.Int, k []byte) (*big.Int, *big.Int)

TODO: double check if it is okay ScalarMult returns k*(Bx,By) where k is a number in big-endian form.

func (*BitCurve) Unmarshal
