Struct Keypair

pub struct Keypair {
    pub secret: SecretKey,
    pub public: PublicKey,
}

An WOTS keypair.

Fields

secret: SecretKey

The secret half of this keypair.

public: PublicKey

The public half of this keypair.

Implementations

impl Keypair

pub fn generate<R>(csprng: &mut R) -> Self

where R: CryptoRng + RngCore,

Generate an WOTS keypair.

Example

use rand::rngs::OsRng;
use wots_rs::Keypair;

let mut csprng = OsRng{};
let keypair: Keypair = Keypair::generate(&mut csprng);

Input

A CSPRNG with a fill_bytes() method, e.g. rand_os::OsRng.

pub fn sign(&self, message: &[u8]) -> Signature

Sign a message with this Keypair using the WOTS algorithm.

Inputs

• message in bytes representation.

Returns

An WOTS Signature on the message.

Example

use rand::rngs::OsRng;
use wots_rs::Keypair;

let mut csprng = OsRng{};
let keypair: Keypair = Keypair::generate(&mut csprng);

let message = b"hello";
let signature = keypair.sign(message);

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

Verify a signature on a message using the WOTS algorithm.

Inputs

• message in bytes representation.
• signature is a purported WOTS Signature on the message.

Returns

Returns true if the signature was a valid signature created by this Keypair on the message.

Example

use rand::rngs::OsRng;
use wots_rs::Keypair;

let mut csprng = OsRng{};
let keypair: Keypair = Keypair::generate(&mut csprng);

let message = b"hello";
let signature = keypair.sign(message);

assert!(keypair.verify(message, signature));
