解读Ubuntu里的密钥环概念

If you use [automatic login in Ubuntu][1] or other Linux distributions, you might have come across a pop-up message of this sort:
如果您用过[ubuntu里的自动登录功能][1]或者其他的Linux发行版, 您可能遇到过这种弹出消息：
**Enter password to unlock your login keyring 请输入密码解锁您的登录密钥环

Why do you use a keyring (also called [keychain][4]) in the real life? You use it to keep one or more keys grouped together so that they are easy to find and carry.

It’s the same concept in Linux. The keyring feature allows your system to group various passwords together and keep it one place.
Linux里也是类似的。密钥环功能使您的系统可以将各种密码放在一起，并将其保存在一个地方。

但是，如果您使用Chromium或[Ubuntu中的Google Chrome][6]之类的浏览器，并使用它来保存各种网站的登录密码，那么您将遇到麻烦。任何人都可以使用浏览器并利用您在浏览器中保存的密码登录网站。那不就是风险吗？
This is why when you try to use Chrome, it will ask you to unlock the keyring repeatedly. This ensures that only the person who knows the keyring’s password (i.e. the account password) can use the saved password in browser for logging in to their respective websites.
这就是为什么当您使用Chrome时，它将重复地提示您先解锁密钥环。这确保了只有知道密钥环密码的人才能使用在浏览器中保存的密码来登录它们相关联的网站。

If you keep on cancelling the prompt for keyring unlock, it will eventually go away and let you use the browser. However, the saved password won’t be unlocked and you’ll see ‘sync paused’ in Chromium/Chrome browsers.
如果您继续取消解锁密钥环的提示，它最终将消失并允许您使用浏览器。但是，保存的密码将不会被解锁，您在Chromium/Chome浏览器上将会看到'同步暂停'的提示。

Don’t worry. You don’t have to ‘fight the daemon’ in the terminal. Most desktop environments come with a graphical application that interacts with this daemon. On KDE, there is KDE Wallet, on GNOME and others, it’s called Password and Keys (originally known as [Seahorse][8]).
