Password Generator

Generate cryptographically strong passwords with customizable lengths and character filters.

Interactive Online Utility

Password Generator runs 100% locally in your browser sandbox with zero network roundtrips. Load or paste your code directly into the workspace above to format, parse, validate, or generate your output instantly.

PRO TIP Local Client-Side Processing

Otuls runs 100% locally in your browser. Your data is processed in-memory and never transmitted over external network connections.

Technical Guide & Overview

Strong cryptographic password generation is the primary defense against credential stuffing, brute-force dictionary attacks, and rainbow table cracking.

How It Works Under the Hood

Otuls samples uniform random integers across character sets (uppercase, lowercase, numbers, high-entropy symbols) using crypto.getRandomValues(). It calculates real-time Shannon entropy bits to measure resistance against offline GPU cracking rigs (Hashcat).

Authoritative Specifications & Primary Standards

Official specifications, RFCs, and authoritative open-source repositories for Password Generator:

Official Manual

National Institute of Standards and Technology authority on password length, entropy, and security.

W3C Standard

Web standard for CSPRNG hardware entropy generation (crypto.getRandomValues).

CLI Equivalents & Terminal Automation

Generate password via OpenSSL:
openssl rand -base64 24
Generates high-entropy base64 string directly from system entropy.
Generate 20-character password using pwgen:
pwgen -s -y 20 1
Standard Linux utility for secure, non-memorizable credentials.

Zero-Knowledge Client-Side Sandboxing

Generated passwords are never logged, stored, or sent across any network connection.
