回复了 ethsol 创建的主题程序员吐槽一下钉钉域名竟然不支持 tls1.3

@zong400 RSA 是很老的算法了，ECC 综合指标显著优于 RSA ，了解技术的都会在 TLS 1.3 里采用 ECC 而不是 RSA

回复了 ethsol 创建的主题程序员吐槽一下钉钉域名竟然不支持 tls1.3

钉钉的域名支持 TLS1.3 ；
你的检测结果中没有显示 TLS 1.3 的原因是你用的 nmap 版本比较旧（ 7.6 版本的 nmap 发布时候还没有 TLS 1.3 协议），换个最新版本 nmap 就可以。

你用的这个 nmap 版本号是 7.60 ，发布日期是 2017-07-31 详见： https://svn.nmap.org/nmap-releases/nmap-7.60/CHANGELOG 。

TLS 1.3 协议是 2018 年 8 月发布的，详见 IETF 文档： https://datatracker.ietf.org/doc/html/rfc8446

nmap 在 2021 年 12 月才支持了 TLS 1.3 ，详见代码提交记录： https://github.com/mzet-/Nmap-for-Pen-Testers/commit/f55c200783af64f2ecb286244056e83098d74e97

最新的 nmap 7.95 版本检测钉钉域名是支持 TLS 1.3 的：
```
$ nmap --script ssl-enum-ciphers -p 443 oapi.dingtalk.com

SSL Labs 检测结果也同样显示支持 TLS 1.3： https://www.ssllabs.com/ssltest/analyze.html?d=oapi.dingtalk.com
p.s. 这个域名还在支持 TLS 1.0 和 TLS 1.1 的原因是还有很多企业不支持更高版本的 TLS 。不过安全团队针对低版本的 TLS 的加密套件做了定制，剔除一些低版本中有重大风险的加密套件。

回复了 laskuma 创建的主题 Python 为什么推荐python?

我推荐学门脚本语言，不一定是Python，ruby、perl都可以。
程序员会门脚本语言的好处就不解释了
