SSL 证书是由称为证书颁发机构 (CA) 的中央机构为域名頒發的数字证书。要获得 SSL 证书，您必须购买证书，然后通过 CA 進行的验证过程。

SSL 证书做两件事：a. 加密从用户浏览器发送到您网站的信息 b. 验证您网站的身份。通过这两件事，SSL 证书保护了您的客户，并相应地增加了他们对您在线业务的信任。如果您的网站要求用户使用密码登录或输入敏感信息（如信用卡详情），这一点尤为重要。

SSL 证书与所有主流浏览器兼容。

很抱歉，我们目前不支持升级/降级。如有需要，您可以购买新证书并将其安装在旧证书所在的同一 Web 服务器上。

虽然安装 SSL 证书并不难，但它需要遵循一系列步骤。您可以在我们的知识库中找到更多信息。
