    Use Zenroom in JavaScript


    Zenroom js bindings 🧰 Zenroom js bindings provides a javascript wrapper of Zenroom, a secure and small virtual machine for crypto language processing.

    npm Dyne.org

    💾 Install

    Stable releases are published on https://www.npmjs.com/package/zenroom that have a slow pace release schedule that you can install with

    yarn add zenroom
    # or if you use npm
    npm install zenroom

    For more cutting edge functionalities there is a pre-release aligned with the last zenroom commit, automatically published, that you can install with

    yarn add zenroom@next
    # or if you use npm
    npm install zenroom@next

    🎮 Usage

    The bindings are composed of two main functions:

    • zencode_exec to execute Zencode. To learn more about zencode syntax look here
    • zenroom_exec to execute our special flavor of Lua enhanced with Zenroom's special effects

    Both of this functions accepts a mandatory SCRIPT to be executed and some optional parameters:

    • DATA
    • KEYS
    • CONF All in form of strings. This means that if you want to pass a JSON you have to JSON.stringify it before.

    Both functions return a Promise.

    To start using the zenroom vm just

    import { zenroom_exec, zencode_exec } from 'zenroom'
    // or if you don't use >ES6
    // const { zenroom_exec, zencode_exec } = require('zenroom')
    // Zencode: generate a random array. This script takes no extra input
    const zencodeRandom = `
      Given nothing
      When I create the array of '16' random objects of '32' bits
      Then print all data
      .then((result) => {
      .catch((error) => {
    // Zencode: encrypt a message.
    // This script takes the options' object as the second parameter: you can include data and/or keys as input.
    // The "config" parameter is also optional.
    const zencodeEncrypt = `
      Scenario 'ecdh': Encrypt a message with the password
      Given that I have a 'string' named 'password'
      Given that I have a 'string' named 'message'
      When I encrypt the secret message 'message' with 'password'
      Then print the 'secret message'`
    const zenKeys = `
        "password": "myVerySecretPassword"
    const zenData = `
          "message": "HELLO WORLD"
    zencode_exec(zencodeEncrypt, {data: zenData, keys: zenKeys, conf:`color=0, debug=0`})
      .then((result) => {
      .catch((error) => {
    // Lua Hello World!
    const lua = `print("Hello World!")`
      .then((result) => {
      .catch((error) => {
    // to pass the optional parameters you pass an object literal eg.
    try {
      const result = await zenroom_exec(`print(DATA)`, {data: "Some data", keys: "Some other data", conf:`color=0, debug=0`});
      console.log(result); // => Some data
    } catch (e) {
