Calculate a Keccak-224 hash from text using UTF-8, Hex, Base64, and other input encodings. Read more
What is Keccak-224?
Keccak-224 is the 224-bit form of the original Keccak SHA-3 competition submission. It uses the Keccak sponge construction, but its domain-separation suffix differs from standardized SHA3-224. The same message therefore produces different Keccak-224 and SHA3-224 digests. See the Keccak specifications summary for the construction and parameters.
How to use this hash calculator
Enter the text, choose how it should be converted to bytes, and select the output encoding. Use Keccak-224 only when a protocol or reference value explicitly names Keccak rather than SHA3-224.
Result example
For example, Keccak-224 of UTF-8 abc is c30411768506ebe1c2871b1ee2e87d38df342317300a9b97a95ec6a8 in Hex.
Important limitations
Keccak-224 is not encryption and an unkeyed digest does not prove authenticity. Do not use a fast general-purpose hash directly for password storage. For new systems that require a standardized algorithm, prefer the SHA-3 function specified by the protocol.
Frequently asked questions
Why does my result differ from another tool?
First confirm whether the expected algorithm is Keccak-224 or SHA3-224, then check the exact bytes, encoding, and line endings.
Can I use the result to verify data?
Yes, when the expected Keccak-224 value comes from a trusted source. To hash raw file bytes, use Keccak-224 File Hash.
