Dilithium

A rust implementation of Dilithium, a KEM standardised by the NIST Post-Quantum Standardization Project, packaged as a Wasm binary.

It is recommended to use Dilithium in a hybrid system alongside a traditional signature algorithm such as ed25519.

Installation

npm i pqc-dilithium

Usage

import * as dilithium from "pqc_dilithium";

// Generate Keypair
let keys = dilithium.keypair();
const pubKey = keys.pubkey;
const privKey = keys.secret;

// Sign a message
const msg = new TextEncoder().encode("message")
let sign = keys.sign(msg);

// Verify a signature

let result = dilithium.verify(sign, msg, pubKey)

var assert = require('assert');

assert.equal(result, true)

// Valid input lengths are found in the `Params` class
assert.equal(pubKey.length, kyber.Params.publicKeyBytes);
assert.equal(privKey.length, kyber.Params.secretKeyBytes);
assert.equal(sign.length,  kyber.Params.signBytes);
