Hash Script - Google Sheet

  var rawHash = Utilities.computeDigest(Utilities.DigestAlgorithm.SHA_1,input);
  var txtHash = '';
  for (j = 0; j < rawHash.length; j ++){
    var hashVal = rawHash[j];
    if (hashVal<0)
      hashVal += 256;
    if (hashVal.toString(16).length == 1)
      txtHash +="0";
    txtHash += hashVal.toString(16);
    }
