Mutual TLS (mTLS) authentication is a common security practice that uses client certificates to ensure traffic between client and server is bidirectionally secure and trusted. mTLS also allows requests that do not authenticate via an identity provider — such as Internet-of-things (IoT) devices — to demonstrate they can reach a given resource.
TLS (传输层安全性协议) ↗ 是一种广泛使用的协议，用于确保网络上的安全通信。它通过加密数据并使用数字证书验证服务器来确保机密性和完整性。
双向 TLS (mTLS) 通过对通信双方进行身份验证添加了额外一层保护。客户端向服务器（在此情况下为 Cloudflare）展示证书，反之亦然。
