What is SHA3-224 Hash Generator

Last reviewed: April 18, 2026

SHA-3 is the latest member of the Secure Hash Algorithm family, based on the Keccak sponge construction and designed as a backup to SHA-2.

SHA3-224 Hash Generator is a browser tool that takes any text and returns a 56-character hexadecimal SHA3-224 digest derived from the Keccak permutation standardized in NIST FIPS 202.

Compared with SHA-2, SHA-3 uses a different sponge construction, making it a strong second-source hash for integrity checks, audit logs, and systems that need algorithm diversity alongside SHA-256.

Why use it

Produce a compact 224-bit fingerprint of configuration files, payloads, or log lines without installing OpenSSL.
Add SHA-3 as a defense-in-depth option next to SHA-2 based integrity checks.
Verify sample values during blockchain, smart contract, and Keccak-family debugging sessions.
Generate deterministic cache keys that do not share internal structure with SHA-2.
Double-check library output when implementing SHA-3 in backend code paths.

Features

One-click SHA3-224 hash output in hexadecimal
Client-side hashing with no server round trip
Copy-ready 56-character digest
Identical algorithm as OpenSSL's -sha3-224 option
Works for any UTF-8 string including JSON, JWT payloads, and log lines

How to use SHA3-224 Hash Generator

Paste or type your text. Drop the string you want to hash into the input panel. Trailing whitespace and newlines affect the digest.
Read the SHA3-224 output. The tool immediately returns the 56-character hexadecimal digest in the output panel.
Copy the hash. Use the copy button to paste the digest into code, tickets, or manifests.

Common errors

Confusing SHA3 with Keccak-256 (Ethereum)

Ethereum uses the pre-standard Keccak-256 variant, not FIPS 202 SHA3-256/224.

Fix: If you are signing Ethereum data, use a dedicated Keccak-256 tool rather than SHA3-224.

Hashing binary files as text

Pasting binary content into a text input changes bytes through encoding, which changes the digest.

Fix: For binary data, hash in a terminal or a file-based tool; this page is for UTF-8 text inputs.

Treating the hash as encryption

SHA3-224 is a one-way hash, not encryption — you cannot recover the original input from the digest.

Fix: Use AES or an asymmetric scheme when you need reversible confidentiality, not a hash.

FAQ

What is the output length of SHA3-224?

224 bits, represented as 56 hexadecimal characters.

Is SHA3-224 the same as Keccak-224?

They share a construction, but FIPS 202 SHA3 uses a different padding rule than the original Keccak submission. Outputs differ for the same input.

Is SHA3-224 secure?

Yes for integrity and fingerprinting. It provides 112-bit collision resistance and is standardized by NIST.

Should I use SHA3-224 for passwords?

No. Use bcrypt, argon2, or scrypt for password storage. Plain SHA3 is too fast to resist offline guessing attacks.

Does this tool send my input to a server?

No. Hashing runs entirely in your browser using client-side JavaScript.

Can I use SHA3-224 for message authentication?

Use HMAC-SHA3 or SHA3 with a keyed construction; a bare hash is not an authentication code.
