NOTICE

THIS PACKAGE IS AN EXPERIMENT FORK OF THE ORIGINAL JOSE. DON'T USE THIS PACKAGE AS IT WILL NOT WORK TO YOUR EXPECTATION.

jose

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.

Dependencies: 0

jose has no dependencies and it exports tree-shakeable ESM. CJS is also supported.

Documentation

jose is distributed via npmjs.com, deno.land/x, cdnjs.com, jsdelivr.com, and github.com.

example ESM import

import * as jose from 'jose'

example CJS require

const jose = require('jose')

JSON Web Tokens (JWT)

The jose module supports JSON Web Tokens (JWT) and provides functionality for signing and verifying tokens, as well as their JWT Claims Set validation.

• JWT Claims Set Validation & Signature Verification using the jwtVerify function
  • Using a remote JSON Web Key Set (JWKS)
  • Using a local JSON Web Key Set (JWKS)
• Signing using the SignJWT class
• Utility functions
  • Decoding Token's Protected Header
  • Decoding JWT Claims Set prior to its validation

Encrypted JSON Web Tokens

The jose module supports encrypted JSON Web Tokens and provides functionality for encrypting and decrypting tokens, as well as their JWT Claims Set validation.

• Decryption & JWT Claims Set Validation using the jwtDecrypt function
• Encryption using the EncryptJWT class
• Utility functions
  • Decoding Token's Protected Header

Implemented specifications

The jose module implements the following specifications:

• JSON Web Signature (JWS) - RFC7515
• JSON Web Encryption (JWE) - RFC7516
• JSON Web Key (JWK) - RFC7517
• JSON Web Algorithms (JWA) - RFC7518
• JSON Web Token (JWT) - RFC7519
• JSON Web Key Thumbprint - RFC7638
• JSON Web Key Thumbprint URI - RFC9278
• JWS Unencoded Payload Option - RFC7797
• CFRG Elliptic Curve ECDH and Signatures - RFC8037
• secp256k1 EC Key curve support - RFC8812

The algorithm implementations have been tested using test vectors from their respective specifications as well as RFC7520.

Supported Runtimes

The jose module is compatible with JavaScript runtimes that support the utilized Web API globals and standard built-in objects or are Node.js.

The following runtimes are supported (this is not an exhaustive list):

• Bun
• Browsers
• Cloudflare Workers
• Deno
• Electron
• Node.js
