PasswordGen

A simple class for cryptographically strong secure password generation

Installation

This is available as a package on npm so you can add this to your project by using npm or yarn

npm

npm install z-password-gen

yarn

yarn add z-password-gen

Usage

In your main JavaScript file, import the class and then generate the new password

import PasswordGen from 'z-password-gen';

let generator = new PasswordGen();

// Set the length of the password, default is 32
generator.setLength(32);

// Set the keyspace - i.e. the characters to choose from
generator.setKeyspace('abcdefghijklmnopqrstuvwxyz');

// Generate the keyspace dynamically, default is luns
// each character in the string passed in denotes one of the character groups
// to choose from, see the "Character Groups" section
generator.generateKeyspace('luns');

// These methods are also chainable
generator.setLength(32).generateKeyspace('lunsw');

// A new password will be generated each time the password property is gotten
// so store this inside a variable if you want to reuse it
console.log(generator.password);

Character Groups

Below are the character groups used in the generateKeyspace method

| Group | Variable | Letter | |---------------------|------------------------------|--------| | lowercase_letters | 'abcdefghijklmnopqrstuvwxyz' | l | | uppercase_letters | 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' | u | | numbers | '1234567890' | n | | special_characters | '!@#$%&*?,./|[]{}()' | s | | whitespace | ' ' | w |

Building

If for some reason, you want to build the files for this library yourself (instead of using the dist folder), you can run the following commands to work locally with it

Note: Don't forget to install the dev dependencies

**Running gulp

gulp # This command builds the files, then watches for any changes in the src directory
gulp build # This command only builds the files
gulp watch # This command only watches the files
