func (*Point) FromJacobian ¶

func (p *Point) FromJacobian(v *PointJacobian) *Point

FromJacobian reverses the Jacobian transform. If the point is ∞ it returns 0, 0.

func (*Point) NewGenerator ¶

func (p *Point) NewGenerator() *Point

func (*Point) NewPoint ¶

func (p *Point) NewPoint(x, y *big.Int) (*Point, error)

func (*Point) Set ¶

func (p *Point) Set(q *Point) *Point

func (*Point) ToBig ¶

func (p *Point) ToBig(x, y *big.Int) (xx, yy *big.Int)

func (*PointJacobian) Add ¶

func (p *PointJacobian) Add(a, b *PointJacobian) *PointJacobian

Add set p = a + b.

func (*PointJacobian) Double ¶

func (p *PointJacobian) Double(v *PointJacobian) *PointJacobian

Add set p = a + a.

func (*PointJacobian) Equal ¶

func (p *PointJacobian) Equal(v *PointJacobian) int

func (*PointJacobian) FromAffine ¶

func (p *PointJacobian) FromAffine(v *Point) *PointJacobian

FromAffine returns a Jacobian Z value for the affine point (x, y). If x and y are zero, it assumes that they represent the point at infinity because (0, 0) is not on the any of the curves handled here.

func (*PointJacobian) ScalarBaseMult ¶

func (p *PointJacobian) ScalarBaseMult(k []byte) *PointJacobian

func (*PointJacobian) ScalarMult ¶

func (p *PointJacobian) ScalarMult(q *PointJacobian, k []byte) *PointJacobian

func (*PointJacobian) Select ¶

func (p *PointJacobian) Select(a, b *PointJacobian, cond int) *PointJacobian

func (*PointJacobian) Set ¶

func (p *PointJacobian) Set(v *PointJacobian) *PointJacobian

func (*PointJacobian) Zero ¶

func (p *PointJacobian) Zero() *PointJacobian
