What is BLAKE2s-256?
BLAKE2s is the 32-bit optimized variant of BLAKE2, designed for embedded systems, ARM processors, and constrained environments. BLAKE2s-256 produces a 256-bit (32-byte) digest. It delivers BLAKE2-level security with lower resource usage than BLAKE2b on 32-bit hardware.
Common use cases:
- Embedded and IoT checksum verification
- ARM-optimized integrity checking
- libsodium and modern crypto library validation
- Compact fast hashing on constrained devices

Programming Examples
const crypto = require("crypto");
const hash = crypto.createHash("blake2s256")
.update("hello", "utf8")
.digest("hex");
console.log(hash); // BLAKE2s-256 hex digestimport hashlib
digest = hashlib.blake2s(b"hello", digest_size=32).hexdigest()
print(digest)Frequently Asked Questions
BLAKE2s vs BLAKE2b — when to use which?
BLAKE2s is optimized for 32-bit platforms and embedded systems. BLAKE2b is optimized for 64-bit servers and desktops. Both are secure.
What is the digest size?
BLAKE2s-256 produces a 256-bit (32-byte) digest, displayed as 64 hex characters.
Is BLAKE2s in OpenSSL?
Recent OpenSSL versions support BLAKE2. Check your version with openssl list -digest-algorithms.
Can I verify file checksums?
Yes, if the publisher provides BLAKE2s-256 checksums. Use File mode for binary files.
