lamport_signature

lamport_signature is a Rust implementation of the Lamport one-time signature scheme.

Difference from the lamport_sigs crate

• lamport_signature can use arbitrary fixed output size digest algorithm implemented in RustCrypto/hashes.
• lamport_signature can use arbitrary RNG (Random Number Generator) implemented in rust-lang-nursery/rand.

Usage

extern crate lamport_signature;
extern crate sha2;
extern crate rand;

use lamport_signature::{PublicKey, PrivateKey, generate_keys};
use sha2::Sha256;
use rand::thread_rng;

let mut rng = thread_rng();
let (mut private_key, public_key) = generate_keys::<Sha256, _>(&mut rng);

let signature = private_key.sign(b"Hello, World!").expect("signing failed");

assert!(public_key.verify(&signature, b"Hello, World!"));
