【网站百科】网站一定要安装SSL证书吗？
黑客事件正在崛起，您的网站安全吗？网络安全在今天已经成为重要的问题，黑客和恶意事件经常见诸报端。但很多运营者还是在犹豫到底需不需要给网站装上ssl证书，我们今天就谈谈是不是一定要安装ssl证书。
一、网站安全需要
传统的http传输是不安全的明文传输方式，敏感信息极易被监听，截取，甚至篡改。部署了ssl证书之后，http升级为https，成为加密传输方式。如果没有ssl 证书，你和服务器之间的任何计算机都可以看到你的银行卡号、用户名和密码及其他敏感信息，这太可怕了！而安装 ssl 证书后，除将信息发送到指定的服务器外，其他任何第三方都无法读取该信息，保护重要信息免受黑客的攻击。
二、浏览器对没有ssl证书的网站不友好
可能您已经注意到，在很多浏览器网址栏经常看到“不安全”三个字的警告。以Chrome浏览器为例，所有没有部署ssl证书的网站，都会显示“不安全”，当你在页面上输入任何信息，这种不安全立马变成及其显眼的红色的“不安全”。这对网站的用户体验是致命性的打击，会在瞬间丧失用户的信任感。
三、搜索引擎更倾向有ssl证书的网站的排名
百度和谷歌均发布公告明确表示https 的站点拥有更好的排名权重。谷歌早已宣布将HTTPS作为排名信号，这意味着网站管理员有机会通过安装ssl加密证书来改善网站SEO排名。谷歌认为200多种算法可以在搜索引擎中提供更高的排名，ssl加密证书的算法便是其中之一。例如，数安时代GDCA的ssl加密证书密钥长度是2048位，加密强度是128位-256位，这么高级别的加密算法当然有助于提升网站的SEO排名。
四、苹果，微软，微信小程序等等强制要求使用ssl证书
如果不部署ssl证书，您会发现您的相关业务无法上线，因为和您关联的这些平台已经将ssl证书列入基本的入门条件。而很多不通公司之间的业务往来，例如API数据对接，同样会要求对接的站点是https加密链接。
五、提升公司形象和客户信任度
部署ssl证书，是一个网站专业度的表现，是对用户信息安全负责的具体体现。https 前缀以及绿色的小锁，以及EV证书的绿色地址栏直接显示公司名字，都在不同程度上给用户带去了人性化和安全感。有机构研究表明，部署了ssl证书尤其是EVssl证书的网站，能有效提升网站的转化率。国外Hubot 研究，如果网站不安全，多达85%的人不会继续浏览。安装ssl证书提高网站安全性，增强消费者的信心，有利于企业提高销售业绩，获得更多利润，在与对手竞争中占据主动地位。
