Password Generator

A random password generator for node and browsers, which makes it possible to choose random-function. It either creates passwords using combinations of characters, digits and symbols, or from words (english or spanish currently).

Installation

npm install password-generator-js

Usage

Node.js

const PasswordGenerator = require('password-generator-js')
let password = PasswordGenerator.generatePassword([options, [randomFunction]])

Browser

<script src="path/to/module/index.js"></script>

let password = PasswordGenerator.generatePassword([options, [randomFunction]])

API

Synchronous

password = PasswordGenerator.generatePassword([options, [randomFunction]])

It is possible to specifiy random function. The function should take no arguments and return a value between 0 and 1.

Asynchronous

password = PasswordGenerator.generatePassword(options, randomFunction[, callback])

password = PasswordGenerator.generatePassword({ length: 20 }, c => {
    let RandomOrg = require('random-org')
    let random = new RandomOrg({ apiKey: '12345-67890-api-key' })
    random.generateDecimalFractions()
        .then(result => {
            c(result.random.data[0])
        });
}).then(console.log.bind(console))

password = PasswordGenerator.generatePassword({ length: 20 }, () => {
    let RandomOrg = require('random-org')
    let random = new RandomOrg({ apiKey: '12345-67890-api-key' })
    return random.generateDecimalFractions()
        .then(result => result.random.data[0]);
}).then(console.log.bind(console))

The random function should take a callback as argument and call it with the result or take no argument and return a promise which resolves with the result.

Options

{
    length: 25,
    uppercase: true,
    lowercase: true,
    digits: true,
    symbols: true,
    obscureSymbols: true,
    extra: ''
}

Extra symbols can be used to add possible characters to the algorithm.

Static

password = PasswordGenerator.generatePassword([options, [randomFunction]])
password = PasswordGenerator.generatePassword(options, randomFunction[, callback])
    .then(callback)

Object oriented

let passwordGenerator = new PasswordGenerator([options, [randomFunction]])

passwordGenerator.options = { ... }
passwordGenerator.random = () => { ... }

password = passwordGenerator.generatePassword([options, [randomFunction]])
password = passwordGenerator.generatePassword(options, [randomFunction[, callback]])
    .then(callback)

Words

Both english and spanish is currently available

Node.js

password = PasswordGenerator.generatePasswordFromWords([length[, language]])

Language is specified as a string such as 'english' or 'spanish'.

Browser

<script src="path/to/module/words/english.js"></script>
<script src="path/to/module/words/spanish.js"></script>

password = PasswordGenerator.generatePasswordFromWords([length[, language]])

Language is specified as a string such as 'english' or 'spanish'.
