FastHashes
FastHashes is a suite of .NET non-cryptographic hash functions.
Main Features
High Performing: optimized implementations make extensive use of method inlining and efficient memory access to maximize hashing throughput.Allocation Free: hashing computations avoid unnecessary intermediate allocations, minimizing garbage collection overhead.Endian-Agnostic: all hashes produce consistent results regardless of the machine's byte order.Platform-Agnostic: the library targets .NET Standard and modern .NET, with support for both x86 and x64 architectures.Fully Managed: since version 3.0.0, the library no longer requires unsafe memory access.
