NAME

       Math::Prime::Util::ECAffinePoint - Elliptic curve operations for affine points

VERSION

       Version 0.57

SYNOPSIS

         # 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();

DESCRIPTION

       This really should just be in Math::EllipticCurve.

       To write.

FUNCTIONS

   new
         $point = Math::Prime::Util::ECAffinePoint->new(a, b, n, x, y);

       Returns a new point at "(x,y,1)" on the curve "(a,b,n)".

   a
   b
   n
       Returns the "a", "b", or "n" values that describe the curve.

   x
   y
       Returns the "x" or "y" values that define the point on the curve.

   f
       Returns a possible factor found during EC multiplication.

   add
       Takes another point on the same curve as an argument and adds it this point.

   mul
       Takes an integer and performs scalar multiplication of the point.

   is_infinity
       Returns true if the point is (0,1), which is the point at infinity for the affine
       coordinates.
