pwdgen-cli

Privacy-first password, passphrase, hex, and Base64URL generation with Web Crypto. Generation happens on the current device; the CLI does not call the PwdGen website or API.

Install

npm install --global pwdgen-cli

CLI

pwdgen generate --mode password --length 20 --count 5 --symbols
pwdgen generate --mode passphrase --words 5 --separator hyphen
pwdgen generate --mode base64url --length 32 --json

JavaScript API

import { generate, generateMany, calculateEntropy } from 'pwdgen-cli';

const password = generate({ mode: 'password', length: 20, symbols: true });
const tokens = generateMany({ mode: 'base64url', length: 32, count: 5 });
const bits = calculateEntropy({ length: 20, alphabetSize: 74 });

Security model

• Uses crypto.getRandomValues() and rejection sampling.
• Never uses Math.random().
• Does not upload, log, persist, or analyze generated values.
• Entropy calculations describe uniformly random selections, not human-created passwords.
