I am trying to get the HashLib library @ https://hashlib.codeplex.com/ working for the new SHA-3 Keccak algorithm. I've written a simple Console application that supposedly has to output the correct hash code, but it doesn't!

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Diagnostics;
using HashLib;
using System.Threading.Tasks;

namespace ConsoleApplication5
{
    class Program
    {
        static void Main(string[] args)
        {
            {
                string passPhrase = "";
                IHash hash = HashFactory.Crypto.SHA3.CreateKeccak512();
                HashResult r = hash.ComputeString(passPhrase, System.Text.Encoding.ASCII);
            
                Console.WriteLine(r.ToString().ToLower().Replace("-",""));
                Console.WriteLine("{0}, {1}, {2}", hash.BlockSize, hash.HashSize, hash.Name);
                Console.ReadLine();
            }
        }
    }
}

The application builds and runs ok, but the output is very wrong. When I use other people 's implementations of the Keccak algorithm, I get different results and it doesn't match for example this wiki post either. https://en.wikipedia.org/wiki/SHA-3 So something is obviously wrong.

When I leave the text empty, as per example, I get the following: "df987cfd23fbc92e7e87faaca300ec3f etc. etc." while the wiki and other tools say I should get

"0eab42de4c3ceb9235fc91acffe746b29c29a8c366b7c60e4e67c466f36a4304c00fa9caf9d87976ba469bcbe06713b435f091ef2769fb160cdab33d3670680e"

,which is something entirely different. I also tried it with non-empty strings of course.

Does anyone have a suggestion?

您的 HashLib 版本太旧。如果您查看最近的更改，您可以看到测试向量从您得到的向量变为您应该得到的向量。（当然，算法也发生了变化。）
