title: KECCAK-256 Hash function in VB6 Or VBA
body: <h2>why keccak-256 is not the chilkat hash olgaritm ?</h2>
  <pre><code>Dim crypt As New ChilkatCrypt2
  crypt.EncodingMode = &quot;hex_lower&quot;
  crypt.HashAlgorithm = **&quot;keccak-256&quot;???**
  Dim bdSeed As New ChilkatBinData
  success = bdSeed.AppendEncoded(&quot;43b337dec65a47b3362c9620a6e6ff39a1ddfa908abab1666c8a30a3f8a7ccccfc24a7914950b6405729a9313cec6ae5bb4a082f92d05ac49df4b6dd8387bfeb&quot;, &quot;hex_lower&quot;)
  MsgBox crypt.HashBdENC(bdSeed)
  </code></pre>
  <p>I wonder why this hash model does not exist in chilkat system?
  Do you have any suggestion or function to VB6 for keccak hash?</p>
