Struct curve25519_dalek::edwards::EdwardsBasepointTable

[+] Show declaration

pub struct EdwardsBasepointTable(_);

[−] Expand description

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.
