lamport_signature

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

Difference from the lamport_sigs crate

• lamport_signature is strongly influenced by the lamport_sigs crate but NO CODES ARE SHARED OR COPIED.
• 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

```rust extern crate lamport_signature; extern crate sha2; extern crate rand;

use lamportsignature::{PublicKey, PrivateKey, generatekeys}; use sha2::Sha256; use rand::thread_rng;

let mut rng = threadrng(); let (mut privatekey, publickey) = generatekeys::(&mut rng);

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

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