在 del.icio.us 上看到的玩意：CAcert.org。這個站台成立的目的是：

It’s been a long time coming, but the wait was worthwhile, finally you are able to get security at the right price… Free!

For years we’ve all been charged high amounts of money to pay for security that doesn’t and shouldn’t cost the earth.

The primary goals are:

Inclusion into mainstream browsers!
To provide a trust mechanism to go with the security aspects of encryption.

在 “CAcert.org Statistics” 可以看到目前的數量，而在 “Root Certificate” 可以 import root certificate。

不過很可惜，要手動 import key… XD
