How it works

Input bytes use prime mixing, rotations, and avalanche finalization to produce a 32- or 64-bit hash. The result suits checksums and hash tables, not deliberate-collision resistance.

  • 64-bit output gives a larger non-cryptographic space.
  • 32-bit output is smaller for compact tables.

Worked example

xxHash of Text
Compute a fast non-cryptographic xxHash32 digest
Input
											hello
Output
												fb0077f9

When to use this

Storage engines, hash tables, and file benchmarks use xxHash.

Edge cases

  • Different seeds change output for identical bytes.
  • Attackers can search collisions more easily than with cryptographic hashes.
  • Endianness and formatting choices affect displayed values.
