Let's Encrypt 免费 SSL 证书发放工具 web 版（第三方）

地址 https://www.sslforfree.com

优点：支持多域名（空格隔开）， web 方式操作，提供 ftp 可自动验证（或者手动上传验证文件）
缺点：因为是第三方工具，所以……提供 ftp 可能涉及到安全问题(建议用临时密码，更建议自行部署)，密钥也可能被网站存下来。

验证的时候总是报： DNS query timed out

@tinyhill 据说是 Let's Encrypt 连不上你家的 NS 服务器。略坑

Hi @yon, I don't think that anyone has developed a Windows GUI for integrating Let's Encrypt with IIS.

To my knowledge the furthest-along project to integrate IIS with Let's Encrypt is

https://github.com/ebekker/letsencrypt-win3.0k

This project uses PowerShell so it can run entirely on Windows, but it is not a GUI; it uses the Windows command line.

I hope it's helpful to you. If you find that it works or doesn't work for your situation, I'm sure the developer could benefit from your feedback. Also remember that you can't get publicly-trusted certificates from Let's Encrypt yet unless you've applied to participate in the beta program and your application has been accepted.

https://www.sslforfree.com LZ 推荐的这个没有开源是吧？

那看起来 @Death 推荐这个更好一些，至少是开源的，不过界面略丑...

其实官方的就挺好用 DNS 问题换 DNS 就行了。阿里的 DNS 验证过连不上 CloudXNS 没有问题
