Programming Examples

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

const hash = crypto.createHash("blake2b512")
  .update("hello", "utf8")
  .digest("hex");

console.log(hash); // BLAKE2b-512 hex digest
Python
import hashlib

digest = hashlib.blake2b(b"hello", digest_size=64).hexdigest()
print(digest)

Frequently Asked Questions

How do I get 512-bit output from BLAKE2b in Node.js?

Use crypto.createHash('blake2b512') or blake2b with digest length 64. This tool outputs the standard BLAKE2b-512 digest.

BLAKE2b-512 vs SHA-512?

Both produce 512-bit digests. BLAKE2b is often faster; SHA-512 has broader legacy support. Match your specification.

Is BLAKE2 standardized?

BLAKE2 is specified in RFC 7693. It is widely implemented in libsodium, OpenSSL (recent versions), and many languages.

Is data processed on a server?

No. BLAKE2b-512 runs locally in your browser.
