证书申请后的下载链接:http://lab.vx.link/ssl/xxx.key,发现当前并不支持https:
curl https://lab.vx.link/ssl/xxx.key -v
* Trying xxxx:443...
* connect to xxxx port 443 failed: 拒绝连接
* Failed to connect to lab.vx.link port 443 after 780 ms: Couldn't connect to server
* Closing connection 0
curl: (7) Failed to connect to lab.vx.link port 443 after 780 ms: Couldn't connect to server
证书本身作为敏感资源,下载链接不使用https是否有点不够安全呢?
