Node SodiumJWT

Features

Fast sodium-based crypto for hashing json web tokens (JWT)

• Relies on sodium-native to perform crypto.
• Built with TypeScript for static type checking with exported types along the library.

Install

npm install @mgcrea/node-sodium-jwt --save

Quickstart

Sign a jwt

import { signSync } from "@mgcrea/node-sodium-jwt";

const payload: Payload = {
  sub: 7,
  iat: new Date("2022-01-03T16:37:48.612Z").getTime(),
};
// Must be 32 bytes long
const secretKey = "0DfgJOaVrb2quroZavPLp7KJm+hTCBN6hZKnsKQSM+o=";
const jwt = signSync(payload, secretKey);

Verify a jwt

import { verifySync } from "@mgcrea/node-sodium-jwt";

const jwt =
  "eyJhbGciOiJIUzUxMlQiLCJ0eXAiOiJKV1QifQ.eyJzdWIiOjcsImlhdCI6MTY0MTIyNzg2ODYxMn0.a3_bFmeD5vugh3p998QXTdPbAuAJFQzCm-2MfmRVEAg";
const secretKey = "0DfgJOaVrb2quroZavPLp7KJm+hTCBN6hZKnsKQSM+o=";
const { header, payload, rotated } = verifySync(payload, secretKey);

Generate a new secretKey

Generate a new secretKey from the bundled cli:

npx @mgcrea/node-sodium-jwt random-bytes

Sign a jwt via CLI

Copy a freshly generated secretKey from the bundled cli:

npx @mgcrea/node-sodium-jwt sign '{"sub": "1"}' '0DfgJOaVrb2quroZavPLp7KJm+hTCBN6hZKnsKQSM+o='

Verify a jwt via CLI

echo -n 'eyJhbGciOiJIUzUxMlQiLCJ0eXAiOiJKV1QifQ.eyJzdWIiOiIxIn0.QdubXBylKLNswV8-b44StbaNQr3SYhqwRBTMn6A6-JM' | npx @mgcrea/node-sodium-jwt verify '0DfgJOaVrb2quroZavPLp7KJm+hTCBN6hZKnsKQSM+o='
