集成 TLS 1.3

🌐 Integrated TLS 1.3

QUIC 协议将 TLS 1.3 直接集成到连接建立和安全性协议中。quic 模块的 API 通过公开与 TLS 相关的信息和配置选项来反映这种集成。目前无法在没有 TLS 的情况下使用 QUIC，也无法使用不同版本的 TLS。

🌐 The QUIC protocol integrates TLS 1.3 directly into the protocol for connection establishment and security. The quic module's API reflects this integration by exposing TLS-related information and configuration options. It is currently not possible to use QUIC without TLS or to use a different version of TLS.

每个 QUIC 会话都从客户端和服务器执行 TLS 握手开始，以协商应用协议（通过 ALPN）、验证服务器（并可选地验证客户端）、交换传输参数，并建立用于加密的共享密钥。

🌐 Every QUIC session starts with the client and server performing a TLS handshake to negotiate the application protocol (via ALPN), authenticate the server (and optionally the client), exchange transport parameters, and establish shared keys for encryption.
