title HTTPS Handshake

Client->Server: 1.协议版本\n2.加密方式列表\n3.支持的压缩算法\n4.random_C
Server->Client: 1.确认协议\n2.确认加密方式\n3.确认压缩方式\n4.random_S\n5.数字证书
note left of Client: 验证证书
note left of Client: 产生Pre-master
note left of Client: enc_key=Fuc(random_C, random_S, Pre-Master)
note left of Client: enc_key加密之前的握手信息得到encrypted_handshake_message
Client->Server: 1.用证书携带的公钥加密后的Pre-Master \n2.参数协商完成通知\n3.encrypted_handshake_message
note right of Server: 用私钥解密得到Pre-Master
note right of Server: enc_key=Fuc(random_C, random_S, Pre-Master)
note right of Server: 用enc_key解密Client传来的encrypted_handshake_message并验证
note right of Server: 用enc_key加密之前的握手信息得到新的encrypted_handshake_message
Server->Client: 1.参数协商完成通知\n2.encrypted_handshake_message
note left of Client:  用enc_key解密Server传来的encrypted_handshake_message并验证
