To create a Non-Profit Certificate Authority; an alternative to the commercial CAs.
Many are just the users of the system who by just making use of the project contribute to the wider community by word-of-mouth.
Many people are currently dissatisfied with the commercial offerings. Many people wish only to connect or share with people they know, or simply secure their webmail from people potentially sniffing their traffic. Why subscribe to a service that is not structured to handle this, and furthermore charges a king's ransom for the privilege?
CAcert Inc., 作为一个社区项目，没有被利益驱使，它在为社会带来保密性和安全性。
根据OpenSSL，PHP 语言 和 MySQL 数据库技术，我们不仅能建立核实你电子邮局和域名的认证，实际上还能建立一个有高度信用度的信任体系。我们的体系进一步是像某些商业CA那样，可以证明你的身份。
When and Where?
Right now it's happening all around you - there are secured websites and email protocols being protected and trusted by people, signed by CAcert.
So what can I do to help the cause?
The simplest and most effective thing you can do is spread the word, by telling your friends, colleagues and relatives about us and join.
