Secure Password Generator Dashboard — Entropy & Strength Analyzer
A developer utility dashboard for generating cryptographically secure passwords.
A developer utility dashboard for generating cryptographically secure passwords. Features real-time entropy estimation in bits, character pool toggles, similar character exclusion, interactive complexity and length gauges, batch generation, and localStorage history.
- Cryptographically secure randomness powered by browser window.crypto.getRandomValues
- Real-time entropy calculation in bits (E = L * log2(N)) with instant reactivity
- Customizable character pools (A-Z, a-z, 0-9, symbols) with similar character exclusion (O, 0, I, l, 1)
- Visual strength overview featuring 3 semicircular SVG gauges for Complexity, Length, and Rating
- Batch password generator (10 at once) with Copy All and persistent localStorage history
Built with: Web Crypto API (CSPRNG), Entropy Estimation, Strength Gauge Visualizers, Vanilla JavaScript, localStorage, CSS Grid / Flexbox, Google Fonts (Sora, Outfit, Chivo Mono)
