X Title: HTTPS 温故知新（五） —— TLS 中的密钥计算
Open Graph Description: 本篇文章我们来对比对比 TLS 1.2 和 TLS 1.3 中的密钥计算。 一. TLS 1.2 中的密钥 在 TLS 1.2 中，有 3 种密钥：预备主密钥、主密钥和会话密钥(密钥块)，这几个密钥都是有联系的。 struct { uint32 gmt_unix_time; opaque random_bytes[28]; } Random; struct { ProtocolVersion client_version; opaque random[46]; } PreMasterSecret; struct { uint8 major; uint8 minor; } ProtocolVersion;
