Trait Implementations

impl From<DomainSeparationTag> for Bls12381G1Sswu

fn from(dst: DomainSeparationTag) -> Self

Performs the conversion.

impl HashToCurveXmd for Bls12381G1Sswu

type Output = G1

The return type by the underlying hash to curve implementation

fn encode_to_curve_xmd<D: BlockInput + Digest<OutputSize = U32>>(
    &self,
    data: &[u8]
) -> Result<Self::Output, HashingError>

Nonuniform encoding. This function encodes byte strings to points in G. The distribution of the output is not uniformly random in G.

fn hash_to_curve_xmd<D: BlockInput + Digest<OutputSize = U32>>(
    &self,
    data: &[u8]
) -> Result<Self::Output, HashingError>

Random oracle encoding (hash_to_curve). This function encodes byte strings to points in G. This function is suitable for applications requiring a random oracle returning points in G, provided that map_to_curve is "well distributed".

impl HashToCurveXof for Bls12381G1Sswu

type Output = G1

The return type by the underlying hash to curve implementation

fn encode_to_curve_xof<X: ExtendableOutput + Input + Reset + Default>(
    &self,
    data: &[u8]
) -> Result<Self::Output, HashingError>

Nonuniform encoding. This function encodes byte strings to points in G. The distribution of the output is not uniformly random in G.

fn hash_to_curve_xof<X: ExtendableOutput + Input + Reset + Default>(
    &self,
    data: &[u8]
) -> Result<Self::Output, HashingError>

Random oracle encoding (hash_to_curve). This function encodes byte strings to points in G. This function is suitable for applications requiring a random oracle returning points in G, provided that map_to_curve is "well distributed".
