X Title: HTTPS 温故知新(六) —— TLS 中的 Extensions

Open Graph Description: 扩展是 TLS 比较重要的一个知识点。它的存在能让 Client 和 Server 在不更新 TLS 的基础上,获得新的能力。扩展的官方文档在 [RFC 6066] [https://tools.ietf.org/html/rfc6066] 中定义。Extension 像 TLS 中的一系列可水平扩展的插件。 Client 在 ClientHello 中申明多个自己可以支持的 Extension,以向 Server 表示自己有以下这些能力,或者向 Server 协商某些协议。Server 收到 ClientHello 以后,依次解析 Extension,有些如果需要立即回应,就在 ServerHello 中作出回应,有些不需要回应,或者 Server 不支持的
