GxHash.128bits.Overloads

GxHash.128bits.Overloads is an extension library for GxHash that provides a comprehensive set of overloads to compute 128-bit hashes on various data types: files, string, ReadOnlySpan(T), Span(T), T[], List(T), Stream, T.

Features

• Compute 128-bit hash (UInt128) for:
  • File contents (string filePath)
  • string values
  • Span<byte> and ReadOnlySpan<byte>
  • Generic Span<T> and ReadOnlySpan<T> where T : unmanaged
  • Arrays T[] where T : unmanaged
  • Lists List<T> where T : unmanaged
  • Stream instances
• Optional seeding for all methods

Installation

Quick Start

using GxHash.Overloads;

class Program
{
    static void Main()
    {
        // Hash a string
        UInt128 hash1 = GxHash128.Hash128("Hello, World!");
        Console.WriteLine($"String hash: {hash1}");

        // Hash with custom seed
        UInt128 seed = new UInt128(1234567890, 9876543210);
        UInt128 hash2 = GxHash128.Hash128("Hello, World!", seed);
        Console.WriteLine($"String hash with seed: {hash2}");

        // Hash a file
        string path = "data.bin";
        UInt128 fileHash = GxHash128.FileContentHash128(path);
        Console.WriteLine($"File hash: {fileHash}");

        // Hash a byte span
        byte[] data = { 1, 2, 3, 4 };
        UInt128 spanHash = GxHash128.Hash128((ReadOnlySpan<byte>)data);
        Console.WriteLine($"Span hash: {spanHash}");

        // Hash a stream
        using var stream = File.OpenRead(path);
        UInt128 streamHash = GxHash128.Hash128(stream, seed);
        Console.WriteLine($"Stream hash: {streamHash}");
    }
}
