Struct lamport_signature::PublicKey

pub struct PublicKey<T> { /* fields omitted */ }

A one-time signing public key.

In general, a public key is generated by the paired PrivateKey or generate_keys function.

Methods

impl<T> PublicKey<T> where
    T: Digest, 

pub fn from_bytes<U>(bytes: &mut U) -> Result<PublicKey<T>, Error> where
    U: Read, 

Constructs a PublicKey from the object implements std::io::Read, like std::fs::File.

Example

extern crate sha2;
extern crate lamport_signature;

use std::fs::File;
use std::io::Read;
use sha2::Sha256;
use lamport_signature::PublicKey;

let mut file = File::open("test_key.pub").unwrap();
assert!(PublicKey::<Sha256>::from_bytes(&mut file).is_ok());

pub fn to_bytes(&self) -> Vec<u8>

Converts the inner key data into a linearized vector.

Example

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

use sha2::Sha256;
use rand::{XorShiftRng, SeedableRng};
use lamport_signature::{PublicKey, generate_keys};

const SEED: [u8; 16] = [0; 16];
let mut rng = XorShiftRng::from_seed(SEED);
let (_, public_key) = generate_keys::<Sha256, _>(&mut rng);
assert!(public_key.to_bytes().len() == 32 * 256 * 2);

pub fn verify(&self, signature: &Signature, data: &[u8]) -> bool

Verifies the Signature.

Example

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

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

const SEED: [u8; 16] = [0; 16];
let mut rng = XorShiftRng::from_seed(SEED);
let (mut private_key, public_key) = generate_keys::<Sha256, _>(&mut rng);

const MESSAGE: &[u8] = b"hello, world!";
let signature = private_key.sign(MESSAGE).expect("failed to sign.");
assert!(public_key.verify(&signature, MESSAGE));
