xxHash
An extremely fast non-cryptographic hash algorithm that processes data at RAM speed limits.
What is xxHash?
xxHash is an extremely fast non-cryptographic hash algorithm that processes data at RAM speed limits. It provides high-performance hashing for applications requiring fast data integrity checks, hash tables, and bloom filters, with variants offering 32-bit, 64-bit, and 128-bit hash outputs. The algorithm is designed to be portable and produce identical results across different platforms.
Developers and engineers working on performance-critical applications such as databases, file systems, network protocols, and data processing pipelines that require fast hashing without cryptographic security.
xxHash offers unparalleled speed, often exceeding RAM bandwidth, while maintaining high-quality hash properties verified by SMHasher tests. Its portability and optimization for both large and small data make it a superior choice over slower alternatives like CityHash, MurmurHash, or cryptographic hashes.
