erc-5564-bn254

Uses the arkworks-rs suite of libraries, and utilities from rln

Usage

use erc_5564_bn254::{random_keypair, generate_stealth_commitment, generate_stealth_private_key};

fn main() {
    let (spending_key, spending_public_key) = random_keypair();
    let (viewing_key, viewing_public_key) = random_keypair();

// generate ephemeral keypair
    let (ephemeral_private_key, ephemeral_public_key) = random_keypair();

    let (stealth_commitment, view_tag) = generate_stealth_commitment(viewing_public_key, spending_public_key, ephemeral_private_key);

    let stealth_private_key_opt = generate_stealth_private_key(ephemeral_public_key, viewing_key, spending_key, view_tag);

    if stealth_private_key_opt.is_none() {
        panic!("View tags did not match");
    }

    let derived_commitment = derive_public_key(stealth_private_key_opt.unwrap());
    assert_eq!(derived_commitment, stealth_commitment);
}
