About this app

Command-line utility for creating or verifying checksums using fast non-cryptographic algorithm xxHash. xxHash is an Extremely fast Hash algorithm, processing at RAM speed limits. Code is highly portable, and produces hashes identical across all platforms (little / big endian). The library includes the following algorithms: - 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. All variants successfully complete the SMHasher test suite which evaluates the quality of hash functions (collision, dispersion and randomness). Additional tests, which evaluate more thoroughly speed and collision properties of 64-bit hashes, are also provided.
