Trait ark_ec::hashing::HashToCurve

pub trait HashToCurve<T: CurveGroup>: Sized {
    fn new(domain: &[u8]) -> Result<Self, HashToCurveError>;
    fn hash(&self, message: &[u8]) -> Result<T::Affine, HashToCurveError>;
}

Trait for hashing arbitrary data to a group element on an elliptic curve

Required Methods

fn new(domain: &[u8]) -> Result<Self, HashToCurveError>

Create a new hash to curve instance, with a given domain.

fn hash(&self, message: &[u8]) -> Result<T::Affine, HashToCurveError>

Produce a hash of the message, which also depends on the domain. The output of the hash is a curve point in the prime order subgroup of the given elliptic curve.
