https的简单学习

HTTPS介绍：

（全称：Hyper Text Transfer Protocol over Secure Socket Layer 或 Hypertext Transfer Protocol Secure，超文本传输安全协议）；

是以安全为目标的HTTP通道，简单讲是HTTP的安全版。即HTTP下加入SSL层，HTTPS的安全基础是SSL，因此加密的详细内容就需要SSL。

nginx的简单配置：

server {
    listen        ssl;
    server_name  localhost;
    ssl_certificate /usr/ssl/nginx.crt;
    ssl_certificate_key /usr/ssl/nginx.key;
    ssl_session_cache    shared:SSL:1m;
    ssl_session_timeout  5m;
    server_tokens off;
    fastcgi_param   HTTPS               on;
    fastcgi_param   HTTP_SCHEME         https;
    access_log /usr/logs/httpsaccess.log;

    ...

}
