keccak256 c# not match solidity

[borisgr04]

Hi @dariogriffo `cs

using (var shaAlg = Sha3.Sha3256()) { var hash = shaAlg.ComputeHash(Encoding.UTF8.GetBytes("11")); return hash.ToHex(false); } ` //result 4410fc15c5a3cde7a2b5366a41dbc95e6547a6021efdff98cfcd5e875e8c3c70

function Insert(string memory transactionId)public pure returns (bytes32) { bytes32 id = keccak256(bytes(transactionId)); return id; } result 0x7880aec93413f117ef14bd4e6d130875ab2c7d7d55a064fac3c2f7bd51516380

Then this result not match

Hi boris, since .net added support for sha3 I'm no longer maintaining this library Look at this https://learn.microsoft.com/en-us/dotnet/api/system.security.cryptography.sha3_256?view=net-8.0

Thank you

Also checked my lib here https://emn178.github.io/online-tools/sha3_256.html result matches https://github.com/dariogriffo/sha3.net/issues/39#issuecomment-2050412466

try 11 there and then go to

https://dotnetfiddle.net/dV1faZ

https://dotnetfiddle.net/ on the left select net6 install the sha3 package and run the following

using System;
using SHA3.Net;

public class Program
{
    public static void Main()
    {
        using (var shaAlg = Sha3.Sha3256())
{   
    var data = shaAlg.ComputeHash(System.Text.Encoding.UTF8.GetBytes("11"));
            string hex = BitConverter.ToString(data).Replace("-", string.Empty).ToLowerInvariant();
            Console.WriteLine(hex);
}
    }
}

Hi,

I required this behavior, but your nuget the result is 4410fc15c5a3cde7a2b5366a41dbc95e6547a6021efdff98cfcd5e875e8c3c70.
