xxHash is an extremely fast non-cryptographic hash algorithm, working at RAM speed limit.
It is proposed in four flavors (XXH32, XXH64, XXH3_64bits and XXH3_128bits). The latest variant, XXH3, offers improved performance across the board, especially on small data.
xxHash has been tested with Austin Appleby’s excellent SMHasher test suite, and passes all tests, ensuring reasonable quality levels. It also passes extended tests from newer forks of SMHasher, featuring additional scenarios and conditions.
This is free and open source software.
- XXH32 : generates 32-bit hashes, using 32-bit arithmetic.
- XXH64 : generates 64-bit hashes, using 64-bit arithmetic.
- XXH3 (since v0.8.0): generates 64 or 128-bit hashes, using vectorized arithmetic. The 128-bit variant is called XXH128.
