What is SHA3-224 Hash Generator?

SHA3-224 is a member of the SHA-3 family standardised in FIPS 202. It uses the Keccak[448] sponge with a 1152-bit rate and produces a 224-bit output.

SHA-3 and SHA-2 are structurally independent — SHA-3 uses the Keccak permutation, not the Merkle-Damgård construction of SHA-2. Use SHA3-224 when a specification or protocol explicitly requires it.

How to Use SHA3-224 Hash Generator

1

Type or paste the text you want to hash

2

Review the generated SHA3-224 output

3

Toggle uppercase if your target system expects capital hex

4

Copy the digest for comparison or storage

Common Use Cases

  • Generating SHA3-224 fixtures for protocol compliance tests.
  • Comparing SHA-3 output length against SHA-2 alternatives.
  • Verifying SHA3-224 implementations across languages.
  • Documenting expected Keccak-based digests in test suites.

Example Input and Output

Generate the FIPS 202 SHA3-224 digest for a short string.

How This Tool Works

The tool encodes input as UTF-8 bytes, applies Keccak-f[1600] with SHA3-224 rate and SHA3 multi-rate padding locally, and formats the 224-bit digest as hexadecimal.

Security note

SHA-3 is structurally independent of SHA-2 and provides an alternative in the event of future SHA-2 weaknesses.

Frequently Asked Questions

How long is a SHA3-224 hash?

SHA3-224 outputs 224 bits, displayed as 56 hexadecimal characters.

What is the difference between SHA3-224 and SHA-224?

SHA-224 is SHA-2 family (Merkle-Damgård); SHA3-224 uses the Keccak sponge. They are structurally different but both produce 224-bit outputs.

Is SHA3-224 secure?

Yes. SHA3-224 is a NIST standard and has no known practical attacks.

Is input uploaded?

No. Hashing runs entirely in your browser.
