What is BLAKE3?

BLAKE3 is a modern cryptographic hash function derived from BLAKE2. It is designed for very high performance and parallelism while maintaining strong security. It produces a default 256-bit hash and supports extendable output length (XOF).

Key characteristics:

  • Extendable output length: Can produce hashes of any length
  • High performance: Fast and parallelizable on modern CPUs
  • Deterministic: The same input always produces the same hash
  • Avalanche effect: Small changes in input produce drastically different outputs
  • Irreversible: Computationally infeasible to reverse the hash to find the original input
  • Collision resistant: Very difficult to find two different inputs that produce the same hash
  • Keyed hashing: Supports an optional 32-byte key for MAC functionality
  • Key derivation: Can derive subkeys from key material and context

Common uses:

  • File integrity verification
  • Content-addressed storage and deduplication
  • Digital signatures and certificates
  • Password storage and authentication
  • Cryptographic protocols and systems
