Trait HashToCurve

pub trait HashToCurve<T>: Sized
where
    T: CurveGroup,
{
    // Required methods
    fn new(domain: &[u8]) -> Result<Self, HashToCurveError>;
    fn hash(
        &self,
        message: &[u8],
    ) -> Result<<T as CurveGroup>::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 as CurveGroup>::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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<T, H2F, M2C> HashToCurve<T> for MapToCurveBasedHasher<T, H2F, M2C>

where T: CurveGroup, H2F: HashToField<<T as CurveGroup>::BaseField>, M2C: MapToCurve<T>,
