1.国密与非国密
什么是国密？

国密即国家密码局认定的国产密码算法。主要有SM1，SM2，SM3，SM4。具体可以参考https://zhuanlan.zhihu.com/p/132352160。

什么是非国密？

就是除了国密以外的算法，包括除国密算法以外的加密算法。

2.国密与非国密和http与https有什么关系？
使用国密算法需要依靠https进行通信。

使用非国密，如果使用了加密算法仍然要依靠https进行通信，没有加密算法可以使用http通信。

3.基于nginx搭建非国密https环境
3.1.下载并解压nginx
本文使用的版本是1.16.1，下载地址是http://nginx.org/download/nginx-1.16.1.tar.gz，下载后上传到服务器进行解压。

tar -zxvf nginx-1.16.1.tar.gz

3.2 携带ssl模块安装nginx

 在解压目录下运行以下命令

./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
make
make install

3.3 查看ssl是否安装成功

/usr/local/nginx/sbin/nginx -V

如果出现以下结果，则表明安装成功。 

3.4启动nginx

cd /usr/local/nginx/sbin
./nginx

3.5配置ssl证书

本文把证书放在/root/notgm目录下

3.6修改nginx配置

修改/usr/local/nginx/conf/nginx.conf

 在最后一个}之前填写以下信息，则表明将开启一个1445端口。

  server {
    listen      1445 ssl;
    #listen      8888;
    server_name  localhost;
    #limit_req zone=reqperip burst=20 nodelay;
    #limit_req zone=reqperserver burst=200 nodelay;
    #limit_conn connperip 20;
    #limit_conn connperserver 500;
    #ssl on;
    ssl_certificate             /root/notgm/server.crt;
    ssl_certificate_key          /root/notgm/server.key;
 
    ssl_client_certificate       /root/notgm/ca.crt;
 
    ssl_verify_client       on;
    
 
    ssl_protocols  SSLv2 SSLv3 TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS !RC4";
   location / {
#    default_type application/json;
 #       return 200 '{"code":200}';
        proxy_pass http://192.168.110.27:8089/;
      }
 
    
    location ~ .*\.(json)$
    {
        default_type application/json;
        return 200 '{"code":200}';
    }
}

3.7 加载nginx.conf

./nginx -s reload

4.验证https通信

https://blog.csdn.net/qq_36313856/article/details/111407772

1、对客户端证书和私钥进行打包处理(需要输入密码,之后在代码中需要用到该密码）
openssl pkcs12 -export -in server.crt -inkey server.key -out client.p12
2、.p12文件转化成JKS格式
keytool -importkeystore -srckeystore client.p12 -srcstoretype pkcs12 -destkeystore client.jks -deststoretype JKS
3、CA根证书转成JKS格式(需要输入密码,之后在代码中需要用到该密码）
keytool -import -noprompt -file ca.crt -keystore ca.jks -storepass 123456
将ca.jks和client.jks放到/usr/local/qwzy/jcqcomponent/
