BLAKE3 Hash Generator
Compute a BLAKE3 digest of text or a file — a tree hash that is faster than BLAKE2 and produces output of any length.
Input
BLAKE3
Enter something above to see the result.
Fast and keyed by design
BLAKE2 came out of the SHA-3 competition finalist BLAKE, tuned for speed on ordinary CPUs. On 64-bit hardware BLAKE2b outruns MD5 while offering security comparable to SHA-3.
It takes a key directly, so it is a MAC without the nested-hash dance HMAC requires. Argon2 — the current recommendation for password hashing — is built on BLAKE2b for exactly this reason.
- BLAKE2b — 64-bit words, digests up to 64 bytes. Use it on any modern machine.
- BLAKE2s — 32-bit words, digests up to 32 bytes. For embedded and 32-bit targets.
Frequently asked questions
BLAKE2 or SHA-256?
SHA-256 where interoperability matters — it is everywhere and hardware-accelerated. BLAKE2 where you control both ends and want throughput, or where you want a keyed hash without HMAC.
What about BLAKE3?
BLAKE3 is faster still, via a tree structure that parallelises. It is not implemented here yet; BLAKE2b covers the same security ground.
