C# port of Keccak, known as SHA3

sha3.net

C# port of Keccak, known as SHA3, based on Bouncy Castle library

How to use it

• Just call any of the four static methods to return the SHA3 with the desired block size

Sha3.Sha3224()

Sha3.Sha3256()

Sha3.Sha3384()

Sha3.Sha3512()

and then call the ComputeHash method:

using (var shaAlg = Sha3.Sha3256())
{   
    var hash = shaAlg.ComputeHash(Encoding.UTF8.GetBytes("abc"));
}

sha3.net's Issues

keccak256 c# not match solidity

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

Implement HashSize and other properties

Set HashAlgorithm.HashSizeValue in the constructor.
Ensure the other properties inherited from HashAlgorithm do return the correct value.

Salt supported?

Is it possible somehow to pass a salt key with this? As we need to match it similar to this
https://wtools.io/generate-hmac-hash using SHA3-512 + salt key

So given the following:
Content: Hello
Salt key: 1234
Hash type: sha3-512
Should result: 8f8a3752ee05d4465f1747918016fe2dd28fc487652efc2d32a8bce90cf8f4e53de87eccd6c0386ec18811ca8cbf37927a47b5266fb16373194be9a9b105f809

Any help would be appreciated
