EllipticCurve

Just the bare implementation for doing some exercises with elliptic curves. See below for usage.

Add this line to your application's Gemfile:

gem 'elliptic_curve'

And then execute:

$ bundle

Or install it yourself as:

$ gem install elliptic_curve

You can define elliptic curves using the EllitpicCurve::EC-class:

ec = EllipticCurve::EC.new( 1, 2, 11 )

which would create an elliptic curve in F_11 of the following form:

y^2 = x^3 + 1 * x + 2

Then you can define a point on this curve:

p = EllitpicCurve::P( ec, 4, 2 )

And do some calculations:

psum = p + p
psum2 = psum + p
if psum2 == p * 3
  puts "is equal, x-axis is: #{psum2.x}"
else
  puts 'some error'
end
