Math::Prime::Util::ECAffinePoint - Elliptic curve operations for affine points
# Create a point on a curve (a,b,n) with coordinates 0,1 my $ECP = Math::Prime::Util::ECAffinePoint->new($a, $b, $n, 0, 1); # scalar multiplication by k. $ECP->mul($k); # add two points on the same curve $ECP->add($ECP2); say "P = O" if $ECP->is_infinity();
This really should just be in Math::EllipticCurve.
$point = Math::Prime::Util::ECAffinePoint->new(a, b, n, x, y);
Returns a new point at
(x,y,1) on the curve
n values that describe the curve.
y values that define the point on the curve.
Returns a possible factor found during EC multiplication.
Takes another point on the same curve as an argument and adds it this point.
Takes an integer and performs scalar multiplication of the point.
Returns true if the point is (0,1), which is the point at infinity for the affine coordinates.
This really should just be in a Math::EllipticCurve module.
