libcrc
A C port of the Murmur3 non-cryptographic hash function, optimized for performance on x86/x64 architectures.
What is libcrc?
murmur3 is a C port of the Murmur3 non-cryptographic hash function, designed for high-speed hashing in applications like hash tables and bloom filters. It provides optimized implementations for x86 and x64 architectures, balancing throughput and latency for different key sizes and system types. The project translates the original C++ code into standard C for compatibility with compilers like gcc.
C developers working on performance-sensitive applications that require efficient hashing, such as database systems, caching mechanisms, or probabilistic data structures.
Developers choose this implementation for its proven performance on x86/x64 hardware, straightforward integration, and public domain licensing. It offers a reliable, fast alternative to cryptographic hashes where security is not a concern.
