常见问题

SSL 证书有什么用？

SSL / TLS 证书为浏览器与服务器之间的通信加密，同时证明「这个站点确实属于它声称的域名」。地址栏的锁形图标、以及 HTTPS 协议，都来自证书。

没有证书或证书无效时，浏览器会拦截并显示安全警告，用户无法正常访问，搜索引擎也会降低信任。

证书到期会怎样？

证书一旦过期，访客打开网站会看到「您的连接不是私密连接」这类整页警告，需要手动点「继续访问」才能进入，绝大多数用户会直接离开。

因此证书一般提前 30 天左右续期。本站结果页按剩余天数标色：绿色为 30 天以上，黄色为 7～30 天，红色为 7 天以内或已过期。

什么是证书链？为什么提示缺少中间证书？

证书由「根证书 → 中间证书 → 服务器证书」三级签发的链条构成。浏览器内置了根证书，但中间证书需要服务器一并下发。

如果服务器只下发了自己的证书、漏掉中间证书，部分浏览器（尤其是较旧的 Android 与部分移动端）会报「证书不受信任」。结果页的「证书链」若只有 1 级，通常就是这种情况。

一张证书能保护多个域名吗？

可以。证书通过 SAN（Subject Alternative Name）扩展同时列出多个域名，称为多域名证书；也可以使用通配符证书保护同一级的所有子域名。

通配符 *.example.com 只覆盖 a.example.com 这一级，不覆盖 a.b.example.com，也不覆盖根域名 example.com 本身，配置时需注意。

为什么查不到证书？

常见原因：该站点没有开启 HTTPS；只在 443 之外的端口提供 HTTPS；防火墙屏蔽了海外或本机访问；服务器未按 SNI 返回对应证书。

本站的检测是从服务器直接发起 TLS 握手读取证书，若目标只允许特定地区访问，结果可能与你在浏览器中看到的不一致。
