The DwellixTools Strong Password & Hash Generator is a fast, cryptographically secure online utility designed to create unhackable passwords and calculate cryptographic hashes instantly.

Powered by modern browser crypto.getRandomValues() APIs, this tool guarantees zero predictable patterns or weak pseudo-random seeds. Customize password lengths up to 128 characters, include uppercase letters, lowercase letters, numbers, and special symbols, exclude ambiguous characters (i, l, 1, O, 0), and inspect real-time entropy security ratings.

Key Features

  • Cryptographically Secure PRNG: Uses window.crypto.getRandomValues() for military-grade randomness.
  • Customizable Password Rules: Set lengths from 8 to 128 characters with granular toggles for uppercase, lowercase, numbers, and symbols.
  • Smart Ambiguous Character Exclusion: Option to remove visually confusing characters like O/0 and l/1/I for easy manual typing.
  • Real-time Entropy & Strength Meter: Visual rating indicator calculating bit entropy (Very Weak, Weak, Medium, Strong, Very Strong).
  • Pronounceable & Memorable Modes: Generate easy-to-remember phonetic passwords or passphrase word combinations.
  • Instant Cryptographic Hash Calculator: One-click calculation of SHA-256, SHA-512, SHA-1, and MD5 hashes for any generated or custom password text.
  • Bulk Password Batch Generator: Generate batches of up to 50 passwords at once for multi-user provisioning.
  • 100% Client-Side Privacy: Passwords and hashes are generated entirely in your browser with zero network transmission.

How to Use the Password & Hash Generator

  1. Adjust Length & Options: Use the slider or number input to select password length (e.g., 16–32 characters).
  2. Toggle Character Sets: Enable or disable uppercase (A-Z), lowercase (a-z), numbers (0-9), and symbols (!@#$%^&*).
  3. Generate & Copy: Click Generate Password or Batch Generate. Click Copy Password for instant clipboard copying.
  4. Calculate Hashes: View real-time SHA-256, SHA-512, and MD5 cryptographic hashes under the generator box.

Frequently Asked Questions (FAQs)

Are generated passwords stored on your server?

No! All passwords and hashes are generated 100% client-side in your web browser using Web Crypto API. No data is ever sent to any remote server or stored anywhere.

We recommend using at least 16 to 24 characters with a mix of uppercase letters, lowercase letters, numbers, and symbols for high entropy (90+ bits).

What is Password Entropy?

Entropy measures how unpredictable a password is in bits. A higher entropy score means it would take exponentially longer for brute-force attacks to guess your password.
