xxhash_cpp
A C++17 port of the extremely fast xxHash non-cryptographic hash algorithm.
What is xxhash_cpp?
xxhash_cpp is a C++17 port of the xxHash library, an extremely fast non-cryptographic hash algorithm designed for high-performance computing scenarios. It provides both 32-bit and 64-bit hash functions that operate at RAM speed limits, solving the need for rapid data hashing in applications like checksums, hash tables, and data deduplication. The library maintains perfect compatibility with the original C implementation while offering a modern, type-safe C++ interface.
C++ developers working on performance-critical applications that require fast hashing, such as game engines, database systems, network protocols, and data processing pipelines. System programmers who need consistent cross-platform hash results will particularly benefit.
Developers choose xxhash_cpp for its exceptional speed (benchmarked as the fastest in its class), simple single-header integration, and guaranteed platform consistency. Unlike other hash libraries, it provides both streaming and one-shot interfaces with comprehensive STL support while maintaining perfect SMHasher quality scores.
