Struct curve25519_dalek::edwards::EdwardsBasepointTable

pub struct EdwardsBasepointTable(_);

A precomputed table of multiples of a basepoint, for accelerating fixed-base scalar multiplication. One table, for the Ed25519 basepoint, is provided in the constants module.

The basepoint tables are reasonably large (30KB), so they should probably be boxed.

Implementations

impl EdwardsBasepointTable

pub fn create(basepoint: &EdwardsPoint) -> EdwardsBasepointTable

Create a table of precomputed multiples of basepoint.

pub fn basepoint(&self) -> EdwardsPoint

Get the basepoint for this table as an EdwardsPoint.
