Security & Cryptov1.0.0

@sopkit/password

Customizable password generator and security entropy analyzer using information entropy.

Overview

Generate secure random string passwords and perform strength checks based on pool variety and bit entropy (Shannon Entropy scale) rather than basic length metrics.

Installation

npm install @sopkit/password

Quick Start (ESM)

import { generate, analyze } from "@sopkit/password";

const pass = generate({ length: 16 });
const res = analyze(pass);

API Reference

Generates secure random password.

analyze(password: string): StrengthResult

Returns score, label, entropy, and tips.
