Implementations

impl GroupElement

pub const BYTES_LEN: usize = 32usize

Size of the byte representation of GroupElement. We always encode the compressed value

pub fn generator() -> Self

pub fn zero() -> Self

pub(crate) fn compress(&self) -> CompressedRistretto

pub fn to_bytes(&self) -> [u8; 32]

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

pub fn from_hash(buffer: &[u8]) -> Self

Point from hash

pub fn sum<'a, I>(i: I) -> Selfwhere I: Iterator<Item = &'a Self>,

pub fn multiscalar_multiplication<I, J>(scalars: I, points: J) -> Selfwhere I: IntoIterator<Item = Scalar>, J: IntoIterator<Item = GroupElement>,

Constant-time multiscalar multiplication using Straus algorithm

pub fn vartime_multiscalar_multiplication<I, J>(scalars: I, points: J) -> Selfwhere I: IntoIterator<Item = Scalar>, J: IntoIterator<Item = GroupElement>,

Variable multiscalar multiplication. This function is vulnerable to side-channel attacks and should only be used when the scalars are not secret.
