Merkle-Trees

Implementation of a Merkle tree using one time signatures, such as Lamport or Winternitz, as leaves

Usage

use sha2::Sha256;
use merkle_trees_cry4::{OneTimeScheme, MerkleSecretKey, MerklePublicKey};

let message = b"Hi There!";

let mut sk = MerkleSecretKey::<Sha256>::new(128, OneTimeScheme::Lamport).unwrap();
let pk = MerklePublicKey::<Sha256>::new(&sk);

let leaf_index = 66;
let sig = sk.sign_arbitrary(message, leaf_index).unwrap();
pk.verify_arbitrary(message, &sig).unwrap();
