dotSiphash

A minimal, fast, cross-platform SipHash for .NET applications.

This library provides access to the SipHash hashing algorithm, which is a fast and secure hash function designed for short inputs. It is particularly useful for hash tables and other applications where performance and security are critical.

Tests are included and available in the Github repo.

NuGet

Features

  • Easy to use: Simple API for hashing
  • Minimal dependencies: No external dependencies required, making it lightweight and easy to integrate.

Requirements

  • .NET 8.0 or later
  • Windows x64, Linux x64, or macOS (x64 & Apple Silicon)

Usage

dotSipHash is a wrapper around the reference implementation of SipHash. It provides a simple API for hashing data using the SipHash algorithm, which is a fast and secure hash function designed for short inputs.


using nebulae.dotSipHash;

// 16-byte SipHash key (must be exactly 16 bytes)
byte[] key = new byte[16] {
    0x00, 0x01, 0x02, 0x03,
    0x04, 0x05, 0x06, 0x07,
    0x08, 0x09, 0x0A, 0x0B,
    0x0C, 0x0D, 0x0E, 0x0F
};

// Data to hash
byte[] message = System.Text.Encoding.UTF8.GetBytes("Hello, SipHash!");

// --- 64-bit hash using byte[] ---
ulong hash64 = SipHash.Compute64(message, key);

// --- 64-bit hash using Span<T> ---
Span<byte> keySpan = key;
Span<byte> dataSpan = message;
ulong hash64Span = SipHash.Compute64(dataSpan, keySpan);

// --- 128-bit hash using byte[] ---
byte[] hash128 = SipHash.Compute128(message, key);

// --- 128-bit hash using Span<T> ---
Span<byte> output = stackalloc byte[16];
bool success = SipHash.TryCompute128(dataSpan, keySpan, output);
