是否可以只计算SHA512散列的一部分？(C#)

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 = new SHA512Managed())
        {
            byte[] hashBytes = sha512.ComputeHash(inputBytes);
            
            // 只计算散列的一部分
            byte[] partialHashBytes = new byte[16];
            Array.Copy(hashBytes, 0, partialHashBytes, 0, 16);
            
            string partialHash = BitConverter.ToString(partialHashBytes).Replace("-", "");
            
            Console.WriteLine("Partial SHA512 hash: " + partialHash);
        }
    }
}
