Prerequisites

Before you start, make sure you have the following installed:

• Node.js and npm

Installation

1. Clone this repository:

   git clone https://github.com/iamrosada/nitro-2fa.git

2. Navigate to the project directory:

   cd nitro-2fa

3. Install the required packages:

   npm install

Usage

Choose Word Source

The chooseWordSource function allows you to select the word source based on your configuration.

const sourceConfig = {
  sourceType: "file",
  userWords: "youruserwords",
  userPassword: "yourpassword",
};

chooseWordSource(sourceConfig)
  .then((result) => {
    console.log("Words Array:", result.wordsArray);
    console.log("Encrypted Data:", result.encryptedData);
  })
  .catch((error) => {
    console.error("Error:", error);
  });

Perform Nitro 2FA Authentication Check

The createNitro2FAContext function creates a context for authentication checks.

const context = createNitro2FAContext();

const words = ["word1", "word2", "word3"];
const userAnswer = "youranswer";

const verificationResult = await context.nitro2FA(words, userAnswer);

if (verificationResult.status === "Correct") {
  console.log("Authentication successful!");
} else {
  console.log("Authentication failed. New question:", verificationResult.newQuestion);
}

Create Nitro 2FA Context

The createNitro2FAContext function creates a context for the Nitro 2FA system, allowing you to retrieve word transformations and verify user answers.

import { createNitro2FAContext } from 'nitro-2fa-auth';

const myContext = createNitro2FAContext();

const transformationInfo = myContext.displayTransformationInfo();
console.log(transformationInfo);

const userAnswer = 'user_answer_here';
const result = myContext.nitro2FA(wordsArray, userAnswer);
console.log(result);

Example with REST API, Nitro 2FA Context

import bodyParser from 'body-parser';
import { chooseWordSource, createNitro2FAContext } from 'nitro-2fa-auth';
import express, { Request, Response } from 'express';


const app = express();
const port = 3000;

app.use(bodyParser.json());

let userPassword = "user_password_here"; 

const myContext = createNitro2FAContext();
let wordsArrayFor2FA: string[] = []; 

app.get('/2fa', async (req: Request, res: Response) => {
  try {
    const words = await chooseWordSource({ sourceType: 'file', userPassword: userPassword });

    wordsArrayFor2FA = words.wordsArray;

    res.json({ message: words.wordsArray, keySaveIntoDatabase: words.encryptedData });
  } catch (error) {
    console.error("Error:", error);
    res.status(500).json({ error: "Internal server error" });
  }
});


app.get('/passwordReset', (req: Request, res: Response) => {
  const transformationInfo = myContext.displayTransformationInfo();
  res.json({ transformationInfo });
});

app.post('/checkAnswer', async (req: Request, res: Response) => {
  try {
    const userAnswer = req.body.user_answer;

    const result = await myContext.nitro2FA(wordsArrayFor2FA, userAnswer);

    res.json(result); 
  } catch (error) {
    console.error("Error:", error);
    res.status(500).json({ error: "Internal server error" });
  }
});

app.listen(port, () => {
  console.log(`Server is listening on port ${port}`);
});

Code Structure

The project's code is organized as follows:

• nitroEncryption.js: Encryption and decryption functions.
• readWordsFromFile.js: Function to read words from a file.
• transformWord.js: Function for transforming words.
• getRandomTransformation.js: Function to get a random transformation.
• provideUserWords.js: Function to provide user-specific words.

Replace placeholders like 'your_password_here' and 'user_answer_here' with actual values.
