实验环境说明​

实验手册中大部分实验以docker环境为主，基于Ubuntu 20.04容器镜像。或者直接运行于Ubuntu 20.04操作系统或虚拟机也可以。比如电脑使用的Windows系统，可以通过安装Docker环境、Linux虚拟机、或者Linux子系统进行实验。其他Linux系统或者macOS系统可以参考本实验内容。

安装docker：

可以参考docker官方安装教程，详见https://docs.docker.com/engine/install/。

创建docker容器：

docker run -d -it --name tongsuolab ubuntu:20.04 bash

执行所有实验，都需要先进入docker容器。进入docker容器：

docker exec -it tongsuolab bash

其他软件，直接在操作系统上安装即可。

  • 支持国密协议的浏览器，比如360企业安全浏览器。
  • Wireshark，用于抓包分析国密协议。

构建铜锁密码库​

基于铜锁密码库源代码进行构建和安装。代码下载地址：

AtomGit地址（推荐）：https://atomgit.com/tongsuo/Tongsuo

GitHub地址：https://github.com/Tongsuo-Project/Tongsuo

下载代码需要使用git工具；构建铜锁密码库需要使用perl、gcc、make等基础开发工具。

安装依赖：

# 需要先更新软件包索引
apt update

apt install git gcc make -y

进入Shell终端执行以下命令：

git clone https://github.com/Tongsuo-Project/Tongsuo

cd Tongsuo

./config --prefix=/opt/tongsuo enable-ntls enable-ssl-trace -Wl,-rpath,/opt/tongsuo/lib64 --debug
make -j
make install

查看安装情况：

ls -l /opt/tongsuo

产看铜锁版本，执行如下命令：

/opt/tongsuo/bin/tongsuo version

SM2&SM3&SM4算法实战​

实战SM4加解密算法​

echo "hello tongsuo" > msg.bin

# SM4-CBC加密
/opt/tongsuo/bin/tongsuo enc -K "3f342e9d67d6ce7be701756af7bac8f2" -e -sm4-cbc -in msg.bin -iv "1fb2d42fb36e2e88a220b04f2e49aa13" -nosalt -out cipher.bin

# SM4-CBC解密
/opt/tongsuo/bin/tongsuo enc -K "3f342e9d67d6ce7be701756af7bac8f2" -d -sm4-cbc -in cipher.bin -iv "1fb2d42fb36e2e88a220b04f2e49aa13" -nosalt -out msg2.bin

# 比较解密的明文和原来的消息是否一样
diff msg.bin msg2.bin

实战SM3杂凑算法​

echo -n "hello tongsuo" | /opt/tongsuo/bin/tongsuo dgst -sm3

结果如下： image.png

实战SM2签名和验签​

# 生成一个随机内容文件
dd if=/dev/urandom of=msg.bin bs=1024 count=1

# SM2私钥签名，签名算法为SM2withSM3，Tongsuo/test/certs/sm2.key来自Tongsuo源代码仓库
/opt/tongsuo/bin/tongsuo dgst -sm3 -sign Tongsuo/test/certs/sm2.key -out sigfile msg.bin

# SM2公钥验签，Tongsuo/test/certs/sm2pub.key来自Tongsuo源代码仓库
/opt/tongsuo/bin/tongsuo dgst -sm3 -verify Tongsuo/test/certs/sm2pub.key -signature sigfile msg.bin

签名正确时，验证成功可以看到： image.png

./a.out

解密出来的明文应该是hello tongsuo， image.png

自签发国密证书​

签发步骤为：

  1. 签发CA根证书
  2. 签发中间CA证书
  3. 签发服务器国密双证书

查看私钥和证书​

命令行查看私钥：

/opt/tongsuo/bin/tongsuo pkey -in certs/server/sm2_sign.key -text -noout

结果如下： image.png

命令行查看证书：

/opt/tongsuo/bin/tongsuo x509 -in certs/server/sm2_sign.crt -text -noout

结果如下： image.png

浏览器查看证书，使用支持360浏览器访问https://ebssec.boc.cn/boc15/login.html，或者其他支持国密协议的浏览器也可以，查看国密证书，截图如下：

实战国密传输协议​

铜锁支持使用 s_client 命令行发起国密传输协议的握手。可以对照国密TLCP标准熟悉国密协议，详见http://c.gb688.cn/bzgk/gb/showGb?type=online&hcno=778097598DA2761E94A5FF3F77BD66DA。

通过命令行跟踪国密握手消息，如下所示：

也可以通过支持国密协议的浏览器访问国密HTTPS服务器，并通过wireshark抓包软件查看协议消息。

通过360浏览器访问https://ebssec.boc.cn/，如图所示：

可以从截图中看出使用的国密传输协议。

同时使用 Wireshark 进行抓包，可以看到 TLCP 的握手消息的详细内容。

./server 127.0.0.1:443

再启动一个终端，启动客户端：

并在客户端发送消息，服务端截图：

Tengine + 铜锁，搭建国密服务器​

下载 Tengine 代码，基于铜锁源码构建 Tengine，如下：

# Tengine依赖pcre和zlib
apt install libpcre3 libpcre3-dev zlib1g zlib1g-dev

git clone https://github.com/alibaba/tengine

cd tengine

./configure --add-module=modules/ngx_tongsuo_ntls \
    --with-openssl=../Tongsuo \
    --with-openssl-opt="--strict-warnings --api=1.1.1 enable-ntls --debug" \
    --with-http_ssl_module --with-stream \
    --with-stream_ssl_module --with-stream_sni --with-debug

make -j

make install

配置Tengine，支持国密HTTPS。配置文件/usr/local/nginx/conf/nginx.conf内容如下：

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    server {
        listen       443 ssl;
        server_name  localhost;

        enable_ntls  on;
        ssl_sign_certificate        sm2_sign.crt;
        ssl_sign_certificate_key    sm2_sign.key;
        ssl_enc_certificate         sm2_enc.crt;
        ssl_enc_certificate_key     sm2_enc.key;

        location / {
            return 200 "body $ssl_protocol:$ssl_cipher";
        }
    }
}

stream {
     server {
        listen       8443 ssl;

        enable_ntls  on;
        ssl_sign_certificate        sm2_sign.crt;
        ssl_sign_certificate_key    sm2_sign.key;
        ssl_enc_certificate         sm2_enc.crt;
        ssl_enc_certificate_key     sm2_enc.key;

        return "body $ssl_protocol:$ssl_cipher";
    }
}

Tengine服务端需要配置国密双证书，可以将之前已经签发好的国密双证书拷贝到Tengine配置目录中，如下：

cp certs/server/{sm2_sign.crt,sm2_sign.key,sm2_enc.crt,sm2_enc.key} /usr/local/nginx/conf/

启动Tengine：

/usr/local/nginx/sbin/nginx

使用铜锁s_client连接Tengine服务器，进行国密TLCP握手：

MySQL国密改造，基于TLS 1.3 + 商密套件​

首先，需要先安装铜锁密码库，参考构建铜锁密码库。

参考以下步骤，基于MySQL源代码，使用铜锁密码库，构建MySQL。

# 安装依赖
apt install gcc g++ cmake patchelf libncurses5-dev pkg-config

# 下载MySQL代码
wget https://downloads.mysql.com/archives/get/p/23/file/mysql-boost-8.0.32.tar.gz

tar xzvf mysql-boost-8.0.32.tar.gz

cd mysql-8.0.32

mkdir build
cd build
cmake .. -DWITH_SSL=/opt/tongsuo/ -DWITH_BOOST=/root/mysql-8.0.32/boost/

make
make install

配置MySQL，/etc/my.cnf如下：

[mysqld]
user 	= root
port    = 3306
basedir	= /usr/local/mysql
datadir = /usr/local/mysql/data
character-set-server = utf8
socket  = /usr/local/mysql/mysql.sock
require_secure_transport = ON
tls_ciphersuites = TLS_SM4_GCM_SM3:TLS_SM4_CCM_SM3
tls_version 	= TLSv1.3
ssl_ca		= /root/Tongsuo/test/certs/sm2-chain-ca.crt
ssl_cert	= /root/Tongsuo/test/certs/sm2-leaf.crt
ssl_key		= /root/Tongsuo/test/certs/sm2-leaf.key

[client]
port    = 3306
socket  = /usr/local/mysql/mysql.sock
default-character-set = utf8

启动MySQL服务器：

# 初始化数据库
/usr/local/mysql/bin/mysqld --initialize

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql

# 启动MySQL
/etc/init.d/mysql start

连接MySQL：

/usr/local/mysql/bin/mysql -uroot -p --ssl-mode=required

结营作业说明​

基于铜锁密码库项目或铜锁生态项目，解决客户、产品或研发中遇到的问题，可以结合个人经验、公司业务或者客户需求。以小组或个人的方式，进行软件设计和开发，不限编程语言和技术栈，最终需要提交设计PPT和代码。

选题方向参考以下，但也不限于此：

  1. 发现铜锁密码库项目和铜锁生态相关项目缺少某些算法或功能，加以补充或增强；
  2. 国密改造过程中发现企业内部的Web服务器（或者网关、代理、中间件等）不支持国密通信（比如国密HTTPS），基于铜锁密码库进行国密改造，以满足企业需求，比如Apache httpd等；
  3. 改造技术栈中的某些模块或库，以支持国密通信，比如Python中的requests库并不支持国密HTTPS通信，考虑使用铜锁密码库改造requests库以支持国密HTTPS通信；
  4. 某些编程语言或运行时还不支持国密算法或国密协议，考虑基于铜锁密码库进行改造，使其支持国密算法或国密协议，比如NodeJS、Rust等；
  5. 网络通信协议国密改造，基于铜锁密码库支持更多的网络协议，比如QUIC、SSH、SFTP、LDAP等；
  6. 基于铜锁密码库开发应用程序，移动端、客户端、服务端不限，或者是一个浏览器插件也可以，比如开发一个带图形界面的密码工具箱，支持SM2/SM3/SM4算法、TLCP协议等功能；

作业提交方式：

  • 给出概要设计和代码。
  • 概要设计可以准备1-2页PPT，讲清楚解决的问题、思路和实现。
  • 代码需要提交到https://atomgit.com/tongsuo/t-camp，先fork该项目，再通过提交变更请求的方式提交代码，（如果没有atomgit平台账号需要先注册）。
  • 以组号或者小组名字在t-camp下创建目录，将所有代码放到该目录下，避免和其他小组冲突；
