This package has been deprecated

Author message:

This module is not maintained anymore. If and when the new algorithms get registered and support for the encryption comes to openssl and node, it'll be added directly to the jose package.

jose-chacha

This is a plugin for the jose package that implements the following Individual Draft

ChaCha derived AEAD algorithms in JSON Object Signing and Encryption (JOSE)
source: https://tools.ietf.org/html/draft-amringer-jose-chacha-01

The following new algorithms are available

• C20P content encryption algorithm
• XC20P content encryption algorithm
• C20PKW content encryption key wrapping algorithm
• XC20PKW content encryption key wrapping algorithm
• ECDH-ES+C20PKW Key Agreement with Elliptic Curve Diffie-Hellman Ephemeral Static
• ECDH-ES+XC20PKW Key Agreement with Elliptic Curve Diffie-Hellman Ephemeral Static

Why a plugin?

1. The draft is an individual draft, breaking changes or lacking adoption may occur, hence its not something desired to be part of jose core package.
2. AEAD_XCHACHA20_POLY1305 is not available in OpenSSL bundled with Node.js yet, in the plugin this cipher is handled via libsodium.

Usage

Installing

npm install jose // jose ^1.16.0 || ^2.0.1 declared as a peer dependency
npm install jose-chacha

const jose = require('jose')
const chacha = require('jose-chacha')
 
;(async () => {
  await chacha // wait for libsodium to be ready!
 
  {
    const key = jose.JWK.generateSync('oct', 256)
    console.log(key.algorithms())
    console.log(jose.JWE.encrypt('foobar', key, { alg: 'dir', enc: 'XC20P' }))
  }
 
  {
    const key = jose.JWK.generateSync('EC', 'P-256')
    console.log(key.algorithms())
    console.log(jose.JWE.encrypt('foobar', key, { alg: 'ECDH-ES+XC20PKW', enc: 'XC20P' }))
  }
})()

Note: This plugin only supports Node.js runtime >= 12.0.0 and Electron >= 6.0.0
