是否存在在C#中产生64位散列大小的散列算法？

using System;
using System.Security.Cryptography;
using System.Text;

public class Program
{
    public static void Main()
    {
        string input = "Hello, world!";
        
        byte[] inputBytes = Encoding.UTF8.GetBytes(input);
        
        using (SHA512 sha512 = SHA512.Create())
        {
            byte[] hashBytes = sha512.ComputeHash(inputBytes);
            
            // 将散列值转换为64位整数
            long hashValue = BitConverter.ToInt64(hashBytes, 0);
            
            Console.WriteLine("Hash value: " + hashValue);
        }
    }
}
