About BLAKE2b
BLAKE2b is a cryptographic hash function released in 2012, the successor to BLAKE (a SHA-3 finalist). BLAKE2b is optimized for 64-bit platforms and produces outputs up to 512 bits. Its default variant produces 512 bits (128 hexadecimal characters).
How it works: BLAKE2b is based on the ChaCha core and strips unnecessary overhead from the original BLAKE. As a result, BLAKE2b is often faster than MD5, SHA-1, and SHA-2 — even SHA-3 — while still offering SHA-3-level security.
BLAKE2b is widely used in Argon2 (the Password Hashing Competition-winning KDF), libsodium, and many systems that need fast, secure hashing. It is great for high-performance checksums, deduplication, and data integrity.
FAQ
How long is a BLAKE2b hash?
A BLAKE2b hash is 512-bit (default) long (128 karakter heksadesimal / 128 hexadecimal characters).
Is my data sent to a server?
No. The BLAKE2b hash is computed entirely in your browser. The text you enter never leaves your device.
