# EllipticCurve

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

## Installation

Add this line to your application's Gemfile:

```ruby

gem 'elliptic_curve'

```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install elliptic_curve

## Usage

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

```
