All Security Tools (4)
Free online security tools make cryptographic operations accessible without requiring a local development environment or trusting a third-party server with sensitive data. Every tool in this collection runs entirely client-side in your browser.
The Password Generator uses the Web Crypto API to produce cryptographically secure random passwords with customizable length, character sets (uppercase, lowercase, numbers, symbols), and optional pronounceability. It generates passwords that meet the strictest enterprise security policies while remaining memorable when required.
The Password Strength Checker analyses passwords in real time against multiple criteria: length, character diversity, common password lists, and entropy estimation. It provides actionable feedback explaining exactly what makes a password weak and how to fix it.
The MD5 Hash Generator and SHA-256 Hash Generator produce cryptographic hash digests from any text input. Use them to verify file integrity, generate checksums, or create hash values for comparison — standard research, testing, and security audit workflows that previously required a terminal or local script.
All tools process data locally. No password, hash input, or security-sensitive string is ever transmitted over the network.
