SHA-3 Hash Generator
Get a SHA-256 fallback, not a real SHA-3 hash — the Web Crypto API does not support SHA-3/Keccak, and no library is included for it.

Frequently Asked Questions
No — the output is explicitly labeled as a SHA-256 fallback with a note explaining why. The Web Crypto API doesn't implement SHA-3/Keccak, and this tool doesn't bundle a separate library for it.
It's a fair question — SHA-3/Keccak is more complex to implement correctly than MD5 or RIPEMD-160, so this tool currently discloses the limitation honestly rather than risk shipping a subtly incorrect implementation.
A JavaScript library like js-sha3, or a command-line tool such as `openssl dgst -sha3-256` (where supported by your OpenSSL build).
No — the SHA-256 fallback computation happens entirely in your browser.
