我是否需要为每一个子域使用单独的SSL证书?

不。通配符SSL证书是一种经济有效的选择，它可以用一个证书保护主域名下的所有子域名。与管理每个子域的单独证书相比，这节省了您的时间和金钱。它还可以确保整个网站的一致和统一的安全性。

为什么我的网站有“不安全网站”的警告?

当你访问一个网站时，你的浏览器会建立一个连接来交换信息。SSL证书对该连接进行加密，确保密码、信用卡号和个人信息等敏感数据不被截获。如果没有SSL证书，这些信息将以纯文本形式传播，从而容易受到黑客的攻击。当您看到“https”时，通常可以判断一个站点已通过安全认证。这也是为什么SSL证书有时被称为https证书或网站安全证书，因为它们为访问者保护您的网站。

现代浏览器优先考虑用户安全，主动阻止访问不安全的网站。“不安全网站”警告作为视觉警报，告知用户他们的数据不安全。这个警告会阻止访问者，并对你网站的声誉产生负面影响。

不安全的网站会给网站所有者和用户带来危险。不过，这个问题很容易通过安装SSL证书来解决。

When you visit a website, your browser establishes a connection to exchange information. An SSL Certificate encrypts this connection, ensuring that sensitive data like passwords, credit card numbers, and personal information remain safe from interception. Without an SSL Certificate, this information travels in plain text, making it vulnerable to hackers. You can often tell a site has been securely certified when you see “https.” This is also why SSL Certificates are sometimes called https certificates or website security certificates, because they secure your site for visitors.

Modern browsers prioritize user safety, actively discouraging visits to unsecured websites. The "non-secure website" warning acts as a visual alert, informing users that their data is not secure. This warning can deter visitors and negatively impact your website's reputation.

Non-secure sites pose dangers to site owners and customers alike. However, this issue is simple to fix by installing an SSL Certificate.

如果我的SSL证书过期了怎么办?
过期的SSL证书会使您的网站面临安全风险。如果没有有效的加密，您的站点和访问者之间的数据传输将变得脆弱。这使得黑客很容易窃取密码和信用卡详细信息等敏感信息。要维持一个安全可靠的网站，请务必在SSL证书到期前更新证书。

What happens if my SSL Certificate expires?
An expired SSL Certificate exposes your website to security risks. Without valid encryption, data transmissions between your site and visitors become vulnerable. This makes it easy for hackers to steal sensitive information like passwords and credit card details. To maintain a secure and trustworthy website, be sure to renew your SSL Certificate before it expires.

如何为我的网站安装SSL证书?
您可以按照帮助中心的分步指南通过主机控制面板安装新的SSL证书，也可以联系客户支持以获得帮助。

在选择SSL证书(有时称为https证书或网站安全证书)时，请评估您的安全需求、数据敏感性和预算。对于博客、个人网站和非敏感网站，域验证(DV)证书就足够了。电子商务平台和敏感数据站点受益于组织验证(OV)证书，以增强信任。处理高度敏感数据(如财务或医疗保健信息)的企业应考虑使用扩展验证(EV)证书来获得最高级别的信任。
