Hash Sha3 512

SHA3-512 generates cryptographically secure 512-bit hashes using the Keccak algorithm. Access via MCP in Cursor, Windsurf, or other AI editors, or call GET /v1/hash/sha3-512 directly. Returns deterministic 128-character hexadecimal output like "a7ffc6f8bf1ed76651c14756a061d662f580ff4de43b49fa82d80a4b80f8434a". SHA-3 offers quantum resistance advantages over SHA-2.

API Endpoint

GET /v1/hash/sha3-512

Code Examples

curl "https://tinyfn.io/v1/hash/sha3-512" \
  -H "X-API-Key: YOUR_API_KEY"
const response = await fetch('https://tinyfn.io/v1/hash/sha3-512', {
  headers: { 'X-API-Key': 'YOUR_API_KEY' }
});
const data = await response.json();
console.log(data);
import requests

response = requests.get('https://tinyfn.io/v1/hash/sha3-512',
    headers={'X-API-Key': 'YOUR_API_KEY'})
data = response.json()
print(data)

FAQ

What's the difference between SHA3-512 and SHA-512?

SHA3-512 uses the Keccak sponge construction while SHA-512 uses Merkle-Damgård. SHA3 offers better quantum resistance and different security properties, though both produce 512-bit hashes.

How do I use SHA3-512 in my AI coding workflow with MCP?

Enable TinyFn's MCP server in your editor like Cursor or Windsurf, then ask your AI assistant to generate SHA3-512 hashes. The AI will call the deterministic function instead of guessing hash values.

What format does SHA3-512 return and how long is it?

Returns a 128-character lowercase hexadecimal string representing the 512-bit hash. For example, 'hello' becomes 'a7ffc6f8bf1ed76651c14756a061d662f580ff4de43b49fa82d80a4b80f8434a'.

Is SHA3-512 suitable for password hashing?

No, use dedicated password hashing functions like bcrypt, scrypt, or Argon2. SHA3-512 is too fast and lacks built-in salting, making it vulnerable to rainbow table attacks.

Can I hash empty strings or very long text with SHA3-512?

Yes, SHA3-512 handles any input length including empty strings. Empty string produces 'a69f73cca23a9ac5c8b567dc185a756e97c982164fe25859e0d1dcc1475c80a6'.
