What is xxHash (XXH64)?

xxHash is an extremely fast non-cryptographic hash algorithm that focuses on speed and performance while maintaining good distribution properties. XXH64 is the 64-bit variant that produces a 64-bit (8-byte) hash value, typically displayed as a 16-character hexadecimal number.

Key characteristics:

  • Extremely fast: Optimized for speed, much faster than cryptographic hash functions
  • Deterministic: The same input always produces the same hash
  • Good distribution: Provides excellent hash distribution for hash tables
  • Non-cryptographic: Not suitable for security purposes, designed for performance
  • Larger output: 64-bit hash provides better collision resistance than 32-bit variants
  • Platform optimized: Uses SIMD instructions when available for maximum speed

Common uses:

  • Hash tables and data structures
  • File integrity checks (non-security)
  • Data deduplication
  • Checksums for data transmission
  • Performance-critical applications
  • Database indexing
  • Cache keys generation
