In order to create a message authentication code to ensure that view state has not been tampered with 用于创建消息身份验证代码( mac ) ,以确保视图状态未被篡改。

The advice can contain the authentication code or , as in this case , it can invoke another method 通知可以包含认证代码,或者就像在这个示例中一样,可以调用其他方法。

Represents the abstract class from which all implementations of hash - based message authentication code hmac must derive 表示基于哈希的消息验证代码( hmac )的所有实现必须从中派生的抽象类。
By default , it includes a message authentication code so that the page can determine whether view state was tampered with 默认情况下,它包含消息身份验证代码( mac ) ,以便页可以确定视图状态是否已被篡改。
By default , it includes a message authentication code so that the page can determine whether view state has been tampered with 默认情况下,它包含消息身份验证代码( mac ) ,这样页可以确定视图状态是否已被篡改。
The only way around this is to require a keyed message authentication code such as sha - 1 hmac , which the 802 . 11 standard does not 它的唯一变通方法是需要一个加密的消息认证代码(如sha - 1 / hmac ) ,而802 . 11标准不需要它。
