EFF Diceware Passphrase
Forked from Emil Bay’s excellent module of the same name.
This is a single-file ESM version of Emil’s excellent module that also removes the sodium-native dependency. Instead, it employs a bring-your-own-crypto approach where you pass a reference to Node’s default crypto module when using the module under Node and it automatically detects and uses the Web Crypto API when running in the browser.
Install
npm i @small-tech/eff-diceware-passphraseExamples
Node.js
import crypto from 'crypto'
import EFFDicewarePassphrase from '@small-tech/eff-diceware-passphrase'
const generate = new EFFDicewarePassphrase(crypto)
const passphrase1 = generate.words(8)
const passphrase2 = generate.entropy(100)
console.log('8 words:', passphrase1.join(' '))
console.log('100 bits of entropy:', passphrase2.join(' '))(You can find this example in and run it from the examples/node folder.)

Bundling
After you’ve installed the dev dependencies using npm i, you can build a single-file ESM bundle by running:
npm run buildOr, for the minified version:
npm run build-minifiedFind the bundles in the dist folder.
The non-minified version is 88kb in size and the minified one is 79kb. The bulk of the size comes from the EFF word list itself, which is 77kb.
