xxhsum is a command-line utility designed to create or verify checksums using the fast non-cryptographic xxHash algorithm. This tool provides an efficient way to ensure data integrity by leveraging the speed and reliability of xxHash.

Key Features:

High-Speed Performance: Processes data at RAM speed limits, making it ideal for large-scale operations.
Multiple Hash Variants: Supports XXH32 (32-bit), XXH64 (64-bit), and XXH3 (optimized for small data with 64 or 128-bit outputs).
Cross-Platform Compatibility: Generates identical hashes across different architectures, ensuring consistency.
Proven Quality: Passes SMHasher test suite evaluations for collision resistance, dispersion, and randomness.
Vectorized Arithmetic: XXH3 leverages SIMD instructions for improved performance on modern CPUs.

Audience & Benefit:
Ideal for developers, data engineers, and system administrators who need fast and reliable checksum verification. xxhsum helps streamline workflows that require frequent hash computations without the overhead of slower cryptographic algorithms.

The tool can be installed via winget, ensuring easy integration into development environments. Its lightweight design and focus on performance make it a valuable addition to any project requiring efficient data hashing.
