Elliptic curves can be represented via different “models” with varying efficiency properties. CurveConfig bundles together the types that are common to all models of the given curve, namely the BaseField over which the curve is defined, and the ScalarField defined by the appropriate prime-order subgroup of the curve.

Required Associated Types

type BaseField: Field

Base field that the curve is defined over.

type ScalarField: PrimeField + Into<<Self::ScalarField as PrimeField>::BigInt>

Finite prime field corresponding to an appropriate prime-order subgroup of the curve group.

Required Associated Constants

const COFACTOR: &'static [u64]

The cofactor of this curve, represented as a sequence of little-endian limbs.

const COFACTOR_INV: Self::ScalarField

Provided Methods

fn cofactor_is_one() -> bool
