What is SHA3-512?

SHA3-512 is the largest standard SHA-3 variant, producing a 512-bit digest. It uses the full Keccak-f[1600] permutation with 512-bit output rate. SHA3-512 provides the longest digest in the SHA-3 family for applications requiring maximum output size within FIPS 202.

Common use cases:

  • FIPS 202 SHA3-512 compliance testing
  • Maximum-length SHA-3 digests for integrity verification
  • Cryptographic library benchmarking
  • Academic research on sponge hash functions

Programming Examples

Node.js
const crypto = require("crypto");

const hash = crypto.createHash("sha3-512")
  .update("hello", "utf8")
  .digest("hex");

console.log(hash); // SHA3-512 hex digest
Python
import hashlib

digest = hashlib.sha3_512(b"hello").hexdigest()
print(digest)  # SHA3-512 hex digest
OpenSSL CLI
echo -n "hello" | openssl dgst -sha3-512 -hex

Frequently Asked Questions

SHA3-512 vs SHA-512 — which to use?

They are different algorithms with the same output size. Use whichever your specification or checksum publisher specifies.

Is SHA3-512 secure?

Yes. SHA3-512 is part of the NIST-standardized SHA-3 family with no known practical attacks.

Why is the digest so long?

512 bits (128 hex characters) provides a large security margin and collision resistance for high-assurance applications.

Is hashing done locally?

Yes. All computation runs in your browser.
