Struct curve25519_dalek::ristretto::RistrettoBasepointTable

source · [−]

pub struct RistrettoBasepointTable(_);

Expand description

A precomputed table of multiples of a basepoint, used to accelerate scalar multiplication.

A precomputed table of multiples of the Ristretto basepoint is available in the constants module:

use curve25519_dalek::constants;
use curve25519_dalek::scalar::Scalar;

let a = Scalar::from(87329482u64);
let P = &a * &constants::RISTRETTO_BASEPOINT_TABLE;
