How to use
- Paste the text from a SHA3-224 specification or test vector.
- Run the tool to calculate the digest.
- Compare all 56 hex characters with the expected value.
- Copy or download it with a note of the chosen algorithm.
Examples
Check a fixture string
The matching output length does not make this interchangeable with SHA-224.

Understand the SHA-3 label
SHA3-224 belongs to the SHA-3 family standardized separately from SHA-2. It is useful when a protocol or test vector specifically names this variant. Its result is 224 bits long, but that does not make it equivalent to SHA-224 or SHA-512/224. When exchanging digests with another system, match both the family and output size. The result on this page is displayed in lowercase hexadecimal characters.
Paste the exact text you want to check. The browser encodes it as UTF-8, calculates the digest in a worker, and leaves the input on your device. If you compare against a raw file checksum, remember that this workspace reads an upload as text; decoding and re-encoding can change binary bytes. A hash is useful for comparing content, while HMAC or a digital signature is needed to authenticate its source. The NIST SHA-3 standard lists SHA3-224 among its fixed-output functions.
For a repeatable check, first compare a short published test vector, then compare your own message. This separates an algorithm mismatch from a source-text mismatch. If the reference uses a Keccak label, verify its padding rule before assuming it is standardized SHA-3.
Frequently asked questions
Is SHA3-224 the same as SHA-224?
No. SHA-3 uses a different construction from SHA-2.
Does it produce 224 bytes?
No. It produces 224 bits, which are 28 bytes or 56 hex characters.
Can it verify a sender?
A hash alone cannot; use a signature or keyed authentication method.
Are uploaded files hashed as raw bytes?
No. The workspace reads files as text and hashes their UTF-8 content.
