About Keccak-256 File Hashing

This tool computes the Keccak-256 hash of any file entirely in your browser. Keccak-256 produces a 256-bit (64 character) fingerprint using the original Keccak sponge construction. This is the same algorithm used by Ethereum. Files are processed locally and never uploaded to any server.
