申请免费的公信CA签发的服务器站点证书(无需注册, 无需等待) ...

前置条件 : 已经购买或租用的域名

操纵步调

• 打开申请页面
  
• 然后按照顺序填写上面的内容
  
• 然后就签发成功了
  

好了下面是具体的步调
操纵步调

• 打开页面
  
• 步调一选择Let's Encrypt
  
• 步调二域名填写你的域名
  
• 证书私钥填写下面的证书私钥或者自己天生RSA2048的私钥也行
  
• ACME账户私钥填写下面的账户私钥或者自己天生RSA2048的私钥也行
  
• 邮箱填写自己的邮箱
  
• 然后确认之后进入第二步
  
• 域名管理添加子域名和text记录
  
• 验证通过之后下载key文件和证书文件
  10.然后就可以得到一个服务器站点证书了
  
• 需要pfx的可以通过工具将私钥和证书合并成pfx
  

更新证书时步调和上面一致
可以将账户私钥进行生存,方便更新使用
