        {
            #region
            switch (PasswordFormat)
            {
                case "SHA1":
                    {
                        passWord = FormsAuthentication.HashPasswordForStoringInConfigFile(PasswordString, "SHA1");
                        break;
                    }
                case "MD5":
                    {
                        passWord = FormsAuthentication.HashPasswordForStoringInConfigFile(PasswordString, "MD5");
                        break;
                    }
                default:
                    {
                        passWord = string.Empty;
                        break;

            }
            return passWord;
