JWA, JWS, JWE, JWT, JWK, JWKS for Node.js, Browser, Cloudflare Workers, Deno, Bun, and other Web-interoperable runtimes
The 'jose' npm package is a JavaScript library that provides a variety of cryptographic operations based on JSON Web Tokens (JWT), JSON Web Encryption (JWE), JSON Web Signature (JWS), and JSON Web Key (JWK). It is designed to be compliant with the JOSE (JSON Object Signing and Encryption) suite of standards, and it supports various algorithms for encryption, decryption, signing, and verification of tokens.
JWT Signing
This code sample demonstrates how to create and sign a JWT with a specified algorithm and secret.
const { SignJWT } = require('jose');
const jwt = await new SignJWT({ 'urn:example:claim': true })
.setProtectedHeader({ alg: 'HS256' })
.setIssuedAt()
.setIssuer('urn:example:issuer')
.setAudience('urn:example:audience')
.setExpirationTime('2h')
.sign(new TextEncoder().encode('your-256-bit-secret'));
console.log(jwt);JWT Verification
This code sample shows how to verify a JWT using a secret key and retrieve the payload and protected header.
const { jwtVerify } = require('jose');
const { payload, protectedHeader } = await jwtVerify(jwt, new TextEncoder().encode('your-256-bit-secret'));
console.log(payload);
console.log(protectedHeader);JWE Encryption
This code sample illustrates how to encrypt a JWT using RSA-OAEP-256 for key management and A256GCM for content encryption.
const { EncryptJWT } = require('jose');
const jwe = await new EncryptJWT({ 'urn:example:claim': true })
.setProtectedHeader({ alg: 'RSA-OAEP-256', enc: 'A256GCM' })
.setIssuedAt()
.setIssuer('urn:example:issuer')
.setAudience('urn:example:audience')
.setExpirationTime('2h')
.encrypt(publicKey);
console.log(jwe);JWE Decryption
This code sample demonstrates how to decrypt a JWE and obtain the payload and protected header using a private key.
const { jwtDecrypt } = require('jose');
const { payload, protectedHeader } = await jwtDecrypt(jwe, privateKey);
console.log(payload);
console.log(protectedHeader);JWK Key Generation
This code sample shows how to generate a public and private key pair for the RS256 algorithm.
const { generateKeyPair } = require('jose');
const { publicKey, privateKey } = await generateKeyPair('RS256');
console.log(publicKey);
console.log(privateKey);The 'jsonwebtoken' package is similar to 'jose' in that it provides functionality for creating and verifying JWTs. It is widely used and has a simpler API for basic JWT operations, but it does not support JWE or more advanced JOSE features.
The 'node-jose' package is another alternative that implements the JOSE suite of standards. It offers similar functionalities to 'jose' but has a different API design and may have different performance characteristics.
The 'jws' package is focused on JSON Web Signatures (JWS). It is a simpler library that allows signing and verifying messages but does not handle JWTs, JWEs, or JWKs directly.
jose is JavaScript module for JSON Object Signing and Encryption, providing support for JSON Web Tokens (JWT), JSON Web Signature (JWS), JSON Web Encryption (JWE), JSON Web Key (JWK), JSON Web Key Set (JWKS), and more. The module is designed to work across various Web-interoperable runtimes including Node.js, browsers, Cloudflare Workers, Deno, Bun, and others.
