SSL交互簡述及nginx雙向認證配置

1、證書生成。html

一、SSL Server生成私鑰/公鑰對。server.key(加密)/server.pub(解密);
二、server.pub生成請求文件server.csr,包含server的一些信息,如域名/申請者/公鑰等;
三、server將server.csr遞交給CA,CA驗證經過,用ca.key和csr加密生成server.cert;
四、server將證書server.cert傳給client,client經過ca.crt解密server.cert。nginx

2、認證交互json

3、SSL認證數據包分析session

1、客戶端請求包app

隨機數:加密

加密套件列表:url

壓縮算法和擴展參數:spa

2、服務端響應包:

3、客戶端隨機數包

 

4、通知祕鑰和加密算法

 

5、握手驗證消息

 

6、通知客戶端加密算法與握手限制消息

 

 

7、加密通訊(3

 4、nginx代理證書配置(附測試腳本)
