func GenerateUsersig ¶
func VerifyUsersig ¶
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 S160 ¶
func S160() *BitCurve
S160 returns a BitCurve which implements secp160k1 (see SEC 2 section 2.4.1)
func S192 ¶
func S192() *BitCurve
S192 returns a BitCurve which implements secp192k1 (see SEC 2 section 2.5.1)
func S224 ¶
func S224() *BitCurve
S224 returns a BitCurve which implements secp224k1 (see SEC 2 section 2.6.1)
func S256 ¶
func S256() *BitCurve
S256 returns a BitCurve which implements secp256k1 (see SEC 2 section 2.7.1)
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
