public static string GetMD5(string sDataIn)

        {

            MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();

            byte[] bytValue, bytHash;

            bytValue = System.Text.Encoding.UTF8.GetBytes(sDataIn);

            bytHash = md5.ComputeHash(bytValue);

            md5.Clear();

            string sTemp = "";

            for (int i = 0; i < bytHash.Length; i++)

            {

                sTemp += bytHash[i].ToString("X").PadLeft(2, '0');

            }

            return sTemp.ToLower();
