Class FowlerNollVo256
Provides an implementation of the FVN (Fowler–Noll–Vo) non-cryptographic hashing algorithm for 256-bit hash values. This class cannot be inherited. Implements the FowlerNollVoHash

Examples
The following example demonstrates how to compute 256-bit FNV-1a hash values using FowlerNollVo256, with configurable byte order and integer conversion.
using System;
using System.Numerics;
using System.Text;
using Cuemon;
using Cuemon.Security;
namespace MyApp.Examples
{
public class FowlerNollVo256Example
{
public void Demonstrate()
{
// Create a FNV-1a 256-bit hash (default algorithm).
var fnv = new FowlerNollVo256();
Console.WriteLine($"Bits: {fnv.Bits}"); // 256
Console.WriteLine($"Algorithm: {fnv.Options.Algorithm}"); // Fnv1a
// Compute hash of a UTF-8 encoded string.
var data = Encoding.UTF8.GetBytes("The quick brown fox jumps over the lazy dog");
var hash = fnv.ComputeHash(data);
Console.WriteLine($"Hash (hex): {hash.ToHexadecimalString()}");
Console.WriteLine($"Hash (b64): {hash.ToBase64String()}");
Console.WriteLine($"Hash length: {hash.GetBytes().Length} bytes");
// Configure byte order independently.
var fnvLe = new FowlerNollVo256(o =>
{
o.ByteOrder = Endianness.LittleEndian;
});
var hashLe = fnvLe.ComputeHash(data);
Console.WriteLine($"LE hash: {hashLe.ToHexadecimalString()}");
// Convert hash to an integer using the built-in converter.
var asBigInt = hash.To(b => new BigInteger(b));
Console.WriteLine($"As integer: {asBigInt}");
}}
