BLAKE3 Hash Generator

Generate BLAKE3 hash values for your text or files - faster and more secure than previous hash functions

100% Client-Side Processing

All file hashing happens directly in your browser. Files are never uploaded to any server, ensuring complete privacy and security for sensitive data. Our implementation produces hash values that are bit-for-bit identical to those generated by command-line tools.

(256 bits)

BLAKE3 can output any length, but common values are 32 bytes (256 bits) or 64 bytes (512 bits)

About BLAKE3

BLAKE3 is a cryptographic hash function that's much faster than MD5, SHA-1, SHA-2, SHA-3, and even BLAKE2. It was designed by Jack O'Connor, Jean-Philippe Aumasson, Samuel Neves, and Zooko Wilcox-O'Hearn.

Key features of BLAKE3:

  • Extremely high speed on modern CPUs
  • Parallel computation capability
  • Can be used as a keyed hash (MAC), key derivation function (KDF), and extendable output function (XOF)
  • Secure against length extension attacks
  • Can produce outputs of any length
