Implementations

impl ShamirSecretSharingExtended

pub fn share(&self, secret: u64, coeffs: &[u64]) -> Vec<(u64, u64)>

Share the secret using the provided polynomial coefficients a[1..t]. Returns n shares as (x_i, y_i) pairs.

pub fn reconstruct(&self, shares: &[(u64, u64)]) -> u64

Reconstruct from any t shares using Lagrange interpolation mod p.
