C# TripleDES NoPadding 时对待加密内容进行补字节（8个字节为一个Block）

补一个空格（半角）：

private static byte[] FormatData(String str)
{var yu = str.Length % 8;if (yu == 0) return Encoding.GetEncoding(Consts.Charset).GetBytes(str);var size = 8 - yu;var arr = new byte[str.Length + size];var data = Encoding.GetEncoding(Consts.Charset).GetBytes(str);var i = 0;for (; i < data.Length; i++){arr[i] = data[i];}for (var j = 0; j < size; j++,i++){arr[i] = Convert.ToByte(' ');}return arr;
}private static byte[] FormatByte(IList<byte> arr)
{var i = 0;for (; i < arr.Count; i++){if (Convert.ToChar(arr[i]) == ' '){break;}}var result = new byte[i];for (var j = 0; j < i; j++){result[j] = arr[j];}return result;
}
