gen-secure-password

gen-secure-password is a library to generate secure password using CryptoJS to make it safer when it stored to database.

Features

• Using hashing algorithm (pbkdf2Sync)
• Able to custom options for more secure password (depends on Device RAM)
• Each password has random iteration
• password is unreadable
• no required dependency as long you already installed NodeJS

Compatibility

All version NodeJS (v0.9.3), pbkdf2Sync added since: v0.9.3

Install

npm install gen-secure-password

Usage

there is an example in folder example for more detail.

By default, this library will return secure password with default configuration.

Generate Secure Password

const GenSecurePassword = require('../libs');

const password = "ThisIsAGoodPasswordIn2023!";
const secPwd = GenSecurePassword.GenerateSecurePassword(password)
console.log(secPwd);

example output:

{
    "hash": "967bdb3665fe6001ca4d2f8b5b2a799abad7c51476a86bb9b1a27c0ad6065494634591177a8d9f233f38354704bdfede27b10753ed6f26f0a95dcacdd9dee03b",
    "salt": "qTM9m3QRVYQLFtpD2AjcHrEv0fGeA5Kex14NzWwYRdg=",
    "iterations": 6593
}

Store the result to database, it allows you to store them separately. example in database will looks like:

    "username": "mrbontor",
    "infoAuth": {
        "hash": "967bdb3665fe6001ca4d2f8b5b2a799abad7c51476a86bb9b1a27c0ad6065494634591177a8d9f233f38354704bdfede27b10753ed6f26f0a95dcacdd9dee03b",
        "salt": "qTM9m3QRVYQLFtpD2AjcHrEv0fGeA5Kex14NzWwYRdg=",
        "iterations": 6593
}

Noted: _when verifying password, we will need _ hash, salt and iterations

Verify Secured Password

const GenSecurePassword = require('../libs');

const password = {
    hash: "967bdb3665fe6001ca4d2f8b5b2a799abad7c51476a86bb9b1a27c0ad6065494634591177a8d9f233f38354704bdfede27b10753ed6f26f0a95dcacdd9dee03b",
    salt: "qTM9m3QRVYQLFtpD2AjcHrEv0fGeA5Kex14NzWwYRdg=",
    iterations: 6593
};
const validatePwd = GenSecurePassword.VerifySecurePassword(secPwd, password);
console.log(validatePwd)
//return Boolean

Configuration

GenSecurePassword.GenerateSecurePassword(password, options)

This library allows you to make more secure password.

default option:

{
    "minIteration": 5000, //minimun 
    "maxIteration": 50000, // there is no maximum value, but consider to use below 500k for better performance.
    "saltLength": 32, // minimum is 16, and consider to use between range 16 - 128 for better performance
}

Description

• minIteration and maxIteration minIteration and maxIteration are used to generate Iterations number. The iterations argument must be a number set as high as possible. The higher the number of iterations, the more secure the derived key will be, but will take a longer amount of time to complete. source: pbkdf2Sync

• saltLength

  saltLength is number to generate Buffer in Byte with type data Buffer. The salt should be as unique as possible. It is recommended that a salt is random and at least 16 bytes long. See NIST SP 800-132 for details. source: pbkdf2Sync

As i mention that we need salt and iteration when verifying the password, the reason is

when converting random or pseudorandom byte sequences to UTF-8 strings, subsequences that do not represent valid code points may be replaced by the Unicode replacement character (U+FFFD). The byte representation of the resulting Unicode string may, therefore, not be equal to the byte sequence that the string was created from.
