Detailed Description

The ecc_curve_t record type is used to represent an elliptic curve.

It holds all of the parameters defining an elliptic curve over a large prime number finite field. The prime used as the modulus is called 'p'. The parameters of the general curve are called 'a' and 'b'. The formula defining the curve is:

// The curve is defined as all possible (x,y) values such that
// x,y are integers in the range 0..p-1 (where p must be an odd prime).
// and the x,y values also satisfy:
y^2 mod p = (x^3 + a*x + b) mod p
