You could also use a custom encryption algorithm to encrypt the username and the password at the client end using WMLScript.
您也可以用WMLScript来编写自定义的加密算法，以对客户端的用户名和密码进行加密。

This is possible only if you use simple algorithms; WMLScript is not powerful enough to support algorithms of the DES category.
这只有在使用简单的算法时才有可能实现；在支持 DES 类的算法上，WMLScript 不够强大。

However, the variable representing the input field value that you pass to the WMLScript function is not initialized until you enter a value in the input box.
