Hash Generator
Compute SHA-1, SHA-256, SHA-384, and SHA-512 hashes of any text. Everything runs locally in your browser — nothing is uploaded.

What hash algorithms are supported?
This tool computes SHA-1, SHA-256, SHA-384, and SHA-512 digests using your browser's built-in Web Crypto API (crypto.subtle.digest). MD5 is not included because modern browsers no longer expose it — SHA-256 or higher is recommended for any real use anyway.
Why do the hashes change with every keystroke?
Hashing is deterministic and near-instant, so the tool recomputes all four digests live as you type, letting you see the exact output for your current input at all times.
Is my text sent anywhere?
No. Hashing happens entirely on your device using the browser's native cryptography engine. Nothing is uploaded, logged, or stored.
