What is xxHash (XXH3 64)?

XXH3 is the modern xxHash algorithm designed for very high speed and excellent distribution. XXH3 64 outputs a 64-bit (8-byte) hash value, typically rendered as a 16-character hexadecimal string. It is a non-cryptographic hash and supports optional seeding for reproducible hashing.

Key characteristics:

  • Extremely fast: Optimized for performance on large inputs
  • Deterministic: The same input and seed always produce the same hash
  • Non-cryptographic: Not suitable for security purposes
  • Good distribution: Great for hash tables and indexing
  • Seeded: Optional seed to diversify hash outputs

Common uses:

  • Hash tables and data structures
  • File integrity checks (non-security)
  • Data deduplication and chunking
  • Cache keys and database indexing
  • High-throughput data pipelines
