keylab

Keylab is a Node.js library designed to simplify the creation and validation of JSON Web Tokens, eliminating the need for prior knowledge in cryptography.

Install

with yarn

yarn add keylab

with pnpm

pnpm add keylab

with npm

npm install keylab

Get Started

Signin a Token with a Private key

// ES256

import {getKeyPair, signJwtWithPrivateKey, Algs} from "keylab"

const keyPairES256 = await getKeyPair({
    keyFormat: "pem",
    algorithmIdentifier: Algs?.ES256,
    keySize: 4096
});

const signedPayloadEs256 = await signJwtWithPrivateKey(
    {
        aid: "12345",
        sub: "sub:12345",
        iss: "issuer:12345",
        aud: ["aud:12345"],
        scp: ["a", "b:c", "d"].join(" ")
    },
    Algs.ES256,
    keyPairES256.privateKey
);

Verify a token with private key (symetric)

• HS256

import {verifyHSTokenWithSecretString, Algs} from "keylab"

const isVerified = await verifyHSTokenWithSecretString(
    signedToken,
    SECRET_STRING,
    Algs.HS256
);

Verify a token with a public OpenID endpoint (asymetric)

• ES512

import {checkTokenValidness} from "keylab"

const signedPayloadEs512 = "ey.....";
const jwksUri = `https://openid.auth.dog/.well-known/jwks.json`;

const isValid = await checkTokenValidness(
    signedPayloadEs512,
    {
        jwksUri
    }
);
