SHA-3/224 generator

5 of 1 ratings

Create a SHA3-224 hash online from any text or file. This SHA3-224 generator returns a fixed 224-bit digest as a 56-character hexadecimal string. It’s great for file integrity checks, content addressing, and API signatures where a compact, modern hash is preferred. Typical needs include SHA3-224 checksum verification, SHA3-224 hash of a string, and calculate SHA3-224 of a file online.

What is SHA3-224?

SHA3-224 is part of the SHA-3 family standardized by NIST (FIPS 202). Unlike SHA-2, SHA-3 uses the sponge construction based on Keccak permutations, providing strong security properties and resistance to length-extension attacks. The output is always 224 bits (56 hex chars).

How to use the SHA3-224 Generator

  1. Enter text or upload a file to hash.
  2. Click Generate to compute the SHA3-224 digest.
  3. Copy the 56-character hex output and compare it with a published checksum or store it for verification.

When should you use it?

  • Integrity checks: Publish/verify a SHA3-224 checksum for downloads, backups, and artifacts.
  • Compact identifiers: Create shorter cryptographic fingerprints for URLs, tokens, or metadata.
  • Standards & research: Evaluate SHA-3 behavior vs. SHA-2 in academic or compliance contexts.

Who is this for?

  • Developers generating deterministic IDs and checksums for APIs and packages.
  • DevOps & QA teams validating build outputs across environments.
  • Security practitioners standardizing on modern hash primitives.
  • Students & researchers comparing SHA-2 and SHA-3 families.

Best practices & caveats

  • Passwords: Don’t store raw SHA3-224 of passwords. Use a KDF such as Argon2, bcrypt, or PBKDF2 with salt and cost factors.
  • Exact bytes matter: Encoding (UTF-8 vs UTF-16), hidden whitespace, and line endings (\n vs \r\n) change the hash.
  • Keccak vs. SHA-3: Keccak-224 and SHA3-224 use different padding; their digests will differ. This tool computes SHA3-224 (FIPS 202).

Examples

SHA3-224 of a string

Input:  "hello world"
Output: dfb7f18c77e928bb56faeb2da27291bd790bc1045cde45f3210bb6c5

SHA3-224 of a file (command-line references)

# macOS/Linux/Windows (OpenSSL 3+)
openssl dgst -sha3-224 /path/to/file

# Python (any OS)
python - <<'PY'
import hashlib, sys
with open(sys.argv[1], 'rb') as f:
    print(hashlib.sha3_224(f.read()).hexdigest())
PY /path/to/file

# Node.js (18+)
node -e "const fs=require('fs');const c=require('crypto');\
const d=c.createHash('sha3-224').update(fs.readFileSync(process.argv[1])).digest('hex');\
console.log(d);" /path/to/file

FAQ

Is SHA3-224 secure?

Yes—for integrity and signing workflows. SHA3-224 is a modern, standardized hash. For passwords, always use a dedicated KDF.

Can I decrypt a SHA3-224 hash?

No. Hashes are one-way. “Decryption” sites only match against precomputed databases (rainbow tables).

Why doesn’t my digest match the publisher’s?

Verify you hashed the exact same bytes: check encoding, newline differences, hidden characters, and ensure you didn’t hash a compressed wrapper instead of the raw file.
