Overview
Calculate MD5, SHA-1, SHA-256, SHA-512 hashes instantly. 100% local — no data collected, no servers.
HashLab — Because every developer needs a hash calculator. A fast, lightweight hash calculator that runs entirely in your browser. Hash text or files with one click — nothing ever leaves your machine. Supported algorithms: • MD5 (128-bit) • SHA-1 (160-bit) • SHA-256 (256-bit) • SHA-512 (512-bit) Two modes: • Text mode — type or paste any string and get all four hashes instantly • File mode — drag and drop or browse to hash any file Output formats: • Hex (lowercase) • Base64 • Grouped (space-separated pairs for easy reading) Privacy first: HashLab requests zero browser permissions. There are no background scripts, no service workers, no analytics, no telemetry, and no network calls — ever. Your data stays on your device. Built for developers: • One-click copy for individual hashes or all at once • Full keyboard navigation and screen reader support • Respects prefers-reduced-motion • Clean, distraction-free interface Under the hood: SHA-1, SHA-256, and SHA-512 are computed using the browser's native Web Crypto API — hardware-accelerated where available. MD5 uses a bundled pure-JavaScript implementation (RFC 1321). Open source: https://github.com/hfa-ny/HashLab Developed by Eloquent Software.
