//! Elliptic Curve

//!

//! Cryptology relies on the difficulty of solving mathematical problems, such as the factor

//! of large integers composed of two large prime numbers and the discrete logarithm of a

//! random eliptic curve.  This module provides low-level features of the latter.

//! Elliptic Curve protocols can provide the same security with smaller keys.

//!

//! There are 2 forms of elliptic curves, `Fp` and `F2^m`.  These curves use irreducible

//! trinomial or pentanomial.  Being a generic interface to a wide range of algorithms,

//! the cuves are generally referenced by [`EcGroup`]
