BLAKE2b, BLAKE2s & BLAKE3 Hash Generator
The fastest modern cryptographic hashes.
About this tool
The BLAKE family delivers cryptographic security at speeds that beat MD5 while being as trustworthy as SHA-3 (BLAKE2 was a SHA-3 finalist). BLAKE2b is tuned for 64-bit platforms, BLAKE2s for smaller ones, and BLAKE3 (2020) adds a tree structure for parallelism and near-limitless speed.
You'll find BLAKE2 inside WireGuard, Argon2 password hashing, and libsodium; BLAKE3 in content-addressed storage and fast file integrity systems. This tool computes all three at once via the audited @noble/hashes library, entirely in your browser.
Like everything on encrypt.tools, this runs entirely in your browser — nothing you enter is transmitted or stored.
Frequently asked questions about BLAKE2 & BLAKE3
Is BLAKE3 faster than SHA-256?+
Yes, dramatically — BLAKE3 can be several times faster than SHA-256, and its tree structure lets it use multiple CPU cores for large inputs. It is one of the fastest secure hash functions available while remaining cryptographically strong.
When should I use BLAKE2 versus BLAKE3?+
BLAKE2 is battle-tested and widely embedded (Argon2, WireGuard, libsodium). BLAKE3 is newer, faster, and ideal for large files or parallel hashing. For interoperability with existing systems, match whatever they already use.
Are BLAKE hashes secure for passwords?+
Plain BLAKE hashes are fast, which is exactly wrong for passwords — you want a slow function. Use Argon2 (which is built on BLAKE2), bcrypt, or scrypt for password storage instead.
