申请多域名SSL证书的要求及注意事项
2022-06-25 09:39:00 【沃通WoTrus】
如果您有多个网站需要部署SSL证书,并且这些网站之间的域名没有任何关联,那么多域名SSL证书是理想之选。下面就来详细说说申请多域名SSL证书的要求及注意事项。
多域名SSL证书可以保护2-250个不同的域名,对网站信息传输以https方式加密,防止信息被监听、截取和篡改,同时利于提高在百度谷歌等搜索引擎中的排名权重和收录。任何正规的网站都可以申请多域名SSL证书,基本没什么要求。
虽然申请多域名SSL证书没什么要求,但是还是要注意以下几点:
1、选择正规可信的CA机构
只有正规可信的CA机构(如Sectigo、Digicert等)颁发的SSL证书才会受到各大浏览器的信任,并且能兼容各种操作平台、PC端、移动端等。
2、选择合适的验证方式
多域名SSL证书支持三种方式方法,即域名验证DV、组织验证OV和扩展验证EV。个人和小型企业更适合DV多域名SSL证书,因为这样的证书更便宜,也更容易安装。OV多域名SSL证书安全性高一些,所以它适用于一些企业网站。在这三种证书中,EV多域名SSL证书的安全性最高,因此它适用于安全性要求更高的网站,比如银行金融、大型电子商务等网站。
3、域名类型是否相符
如果您在申请时发现所有域名都是同一主域名下的不同二级域名,则不需要匹配多域名证书。在这种情况下,可以考虑一下通配符证书,因为这个无限子域具有高性价比,所以它更具成本效益。
多域名SSL证书是一种简单而强大的工具,可以保护您在各种域和子域上创建的所有网站。
