用MD5算法實現信息加密C#代碼

	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();
        }
		
		
在程序中調用:
            String s = GetMD5("123456");
            MessageBox.Show(s);
			
			

獲取MD5值：
    Response.Write(System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(TextBox2.Text, "MD5"));
