Hash Generator
Type text and pick an algorithm — the hash updates live. Computed locally with the browser's built-in Web Crypto (no library, nothing uploaded).
About Hash Generator
A cryptographic hash turns any input into a fixed-length fingerprint; the same input always produces the same hash, and even a tiny change produces a completely different one. SHA-256 is the modern default for integrity checks and fingerprints. SHA-1 is included for legacy compatibility but is considered broken for security use. This tool uses the browser's native Web Crypto API, so your text never leaves the page.
