To create a Non-Profit Certificate Authority; an alternative to the commercial CAs.


CAcert 的核心成員一般有很強的信息技術和安全功底,還應該有一個強烈的回報社會的慾望。

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., 作為一個社區項目,沒有被利益驅使,它在為社會帶來保密性和安全性。


根據OpenSSL,PHP 語言 和 MySQL 數據庫技術,我們不僅能建立核實你的電子郵件地址和域名的認證,實際上還能建立一個有高度信用度的信任體系。我們的體系進一步是像某些商業CA那樣,可以證明你的身份。

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.
