        {
            if (string.IsNullOrWhiteSpace(sourceString))
                return null;
            else
            {
                SecureString objSecureString = new SecureString();
                foreach (char c in sourceString.ToCharArray())
                    objSecureString.AppendChar(c);
                return objSecureString;
            }
        }
