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
Type or paste the text you want to hash
Review the generated SHA3-224 output
Toggle uppercase if your target system expects capital hex
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.

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.
Technical Stack
Variant
FIPS 202 SHA3-224 — Keccak[448], rate=1152 bits, capacity=448 bits.
Security note
SHA-3 is structurally independent of SHA-2 and provides an alternative in the event of future SHA-2 weaknesses.
