Functions

func Attack

func Attack(ks []*keys.RSA, ch chan error)

Attack implements the Qi Cheng attack.

Types

type Curve

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

Curve represents the curve y^2 = x^3 + a.

func NewCurve

func NewCurve(x, y *fmp.Fmpz, r *Integers) *Curve

NewCurve creates a curve.

func (*Curve) BInvariants

func (e *Curve) BInvariants(r *Integers)

BInvariants sets the B invariants (b2,4,6 and 8) on curve e in the ring r.

func (*Curve) Poly

func (e *Curve) Poly(n, x *fmp.Fmpz, r *Integers) *fmp.Fmpz

Poly calculates a set of polynomials in the univariate polynomial ring in x over the ring of integers r. Ported from sagemath source.

type Integers

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

Integers is a Ring of integers modulo n.

func NewIntegers

func NewIntegers(n *fmp.Fmpz) *Integers

NewIntegers constructs a new Ring of Integers with modulo n and returns it.

func (*Integers) RandomElement

func (i *Integers) RandomElement() *fmp.Fmpz

RandomElement chooses a random element in the Ring i.
