Struct lamport_signature::PrivateKey

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

A one-time signing private key.

Methods

impl<T> PrivateKey<T>

pub fn used(&self) -> bool

Whether or not the PrivateKey was used.

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

pub fn new<R>(rng: &mut R) -> PrivateKey<T> where
    R: RngCore, 

Constructs a PrivateKey with Digest algorithm type and the specified RNG.

pub fn public_key(&self) -> PublicKey<T>

Generates a PublicKey from the PrivateKey.

pub fn sign(&mut self, data: &[u8]) -> Result<Signature, Error>

Signs the data.

Example

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

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

const SEED: [u8; 16] = [0; 16];
let mut rng = XorShiftRng::from_seed(SEED);
let mut private_key = PrivateKey::<Sha256>::new(&mut rng);
const MESSAGE: &[u8] = b"hello, world!";
assert!(private_key.sign(MESSAGE).is_ok());
