#### **专业**攻击 { #a-professional-attack }

当然，攻击者不用手动操作，而是编写每秒能执行成千上万次测试的攻击程序，每次都会找到更多正确字符。

但是，在您的应用的**帮助**下，攻击者利用时间差，就能在几分钟或几小时内，以这种方式猜出正确的用户名和密码。

#### 使用 `secrets.compare_digest()` 修补 { #fix-it-with-secrets-compare-digest }

在此，代码中使用了 `secrets.compare_digest()`。

简单的说，它使用相同的时间对比 `stanleyjobsox` 和 `stanleyjobson`，还有 `johndoe` 和 `stanleyjobson`。对比密码时也一样。

在代码中使用 `secrets.compare_digest()` ，就可以安全地防御这整类安全攻击。
