dilithium-sign

Dilithium Signature JS

The JS module of the post-quantum digital signature algorithm (Dilithium).

For more information about the Dilithium post-quantum digital signature algorithm, please refer to the following link: Dilithium

Installation

from npm

npm install dilithium-sign

from git

git clone [e-mail]:pqcsf/dilithium-sign-js.git
cd dilithium-sign-js

Quick Start

Dilithium2:

const { getKernel } = require('dilithium-sign');
(async () => 
{
    let Dilithium2 = await getKernel('dilithium2_n3_v1'); //get dilithium2_n3_v1 Kernel
    //gernkey
    let keypair = Dilithium2.genkey(); //return { sk, pk, genKeySeed }
    //sign
    let text = 'TEST MSG';
    let sign = Dilithium2.sign(text, keypair.sk);
    //verify
    console.log(Dilithium2.verify(sign, text, keypair.pk));
    //create public key by private key
    let pk = Dilithium2.publicKeyCreate(keypair.sk);
})();

Dilithium3:

Only the name of getKernel needs to be changed. (dilithium2_n3_v1 -> dilithium3_n3_v1)

const { getKernel } = require('dilithium-sign');
(async () => 
{
    let Dilithium3 = await getKernel('dilithium3_n3_v1'); //get dilithium2_n3_v1 Kernel
    //gernkey
    let keypair = Dilithium3.genkey(); //return { sk, pk, genKeySeed }
    //sign
    let text = 'TEST MSG';
    let sign = Dilithium3.sign(text, keypair.sk);
    //verify
    console.log(Dilithium3.verify(sign, text, keypair.pk));
    //create public key by private key
    let pk = Dilithium3.publicKeyCreate(keypair.sk);
})();

Use specific seeds to generate key pairs

let seed = new Uint8Array(.....);
let keypair = Dilithium2.genkey(seed);

Seed length according to: Dilithium2.genkeySeedByte, different algorithms may have different lengths.

Generate the same signature

const salt = new Uint8Array(.....);
let sign = Dilithium2R.sign(text, keypair.sk, salt);

Salt length according to: Dilithium2R.signSaltByte, different algorithms may have different lengths. Note: Only Dilithium2_R, Dilithium3_R, Dilithium5_R, Dilithium2_AES_R, Dilithium3_AES_R and Dilithium5_AES_R support salt setting
