xkcd-passphrase

Overview

A passphrase generator inspired by xkcd #936, designed to provide a high level of security and memorability. By default, passwords are generated with strength equivalent to a random 128-bit key.

Usage caveats:

  • If end consumers of these generated passphrases are given the ability to easily regenerate and cycle through them until they find ones they like, the level of security provided drops substantially.

  • While the architecture has been vetted by Cure53, the code itself has not yet been audited. Use at your own risk.

Example Usage

import {xkcdPassphrase} from 'xkcd-passphrase';

console.log(await xkcdPassphrase.generate());
/* collision pest numerous baboon tarnish aimee airgas swivel navigate */

console.log(await xkcdPassphrase.generate(256));
/*
	* provolone email darkish symptom unending bridges bianca carport culminate vacancy
	* rehydrate disjoin rotten cornball mousiness cephalon appear buddhism vanity

console.log(await xkcdPassphrase.generate(512));

console.log(await xkcdPassphrase.generate(32, [
	'my',
	'awful',
	'custom',
	'word',
	'list',
	'that',
	'I',
	'created',
	'while',

]));
