truelicense's Introduction

前言

License,即版权许可证,一般用于收费软件给付费用户提供的访问许可证明。根据应用部署位置的不同,一般可以分为以下两种情况讨论:

  • 应用部署在开发者自己的云服务器上。这种情况下用户通过账号登录的形式远程访问,因此只需要在账号登录的时候校验目标账号的有效期、访问权限等信息即可。
  • 应用部署在客户的内网环境。因为这种情况开发者无法控制客户的网络环境,也不能保证应用所在服务器可以访问外网,因此通常的做法是使用服务器许可文件,在应用启动的时候加载证书,然后在登录或者其他关键操作的地方校验证书的有效性。

本文只考虑代码层面的许可限制,暂不考虑逆向破解问题。

SpringBoot 整合 TrueLicense

添加依赖

    <dependency>
        <groupId>de.schlichtherle.truelicense</groupId>
        <artifactId>truelicense-core</artifactId>
        <version>1.33</version>
        <scope>provided</scope>
    </dependency>

TrueLicense 的 de.schlichtherle.license.LicenseManager 类自带的 verify 方法只校验了我们后面颁发的许可文件的生效和过期时间,然而在实际项目中我们可能需要额外校验应用部署的服务器的 IP 地址、MAC 地址、CPU 序列号、主板序列号等信息,因此我们需要复写框架的部分方法以实现校验自定义参数的目的。

TrueLicense 创建、安装证书

使用 keytool 生成公私钥证书库

例如:私钥库密码为 priwd123456,公钥库密码为 pubwd123456,生成步骤如下:

# 1. 生成私钥库
# validity:私钥的有效期(天)
# alias:私钥别称
# keystore:私钥库文件名称(生成在当前目录)
# storepass:私钥库密码(获取 keystore 信息所需的密码,密钥库口令)
# keypass:别名条目的密码(密钥口令)
keytool -genkeypair -keysize 1024 -validity 3650 -alias "privateKey" -keystore "privateKeys.keystore" -storepass "pubwd123456" -keypass "priwd123456" -dname "CN=localhost, OU=localhost, O=localhost, L=SH, ST=SH, C=CN"

# 2. 把私钥库内的公钥导出到一个文件当中
# alias:私钥别称
# keystore:私钥库的名称(在当前目录查找)
# storepass:私钥库的密码
# file:证书名称
keytool -exportcert -alias "privateKey" -keystore "privateKeys.keystore" -storepass "pubwd123456" -file "certfile.cer"

# 3.再把这个证书文件导入到公钥库,certfile.cer 没用了可以删掉了
# alias:公钥名称
# file:证书名称
# keystore:公钥文件名称
# storepass:公钥库密码
keytool -import -alias "publicCert" -file "certfile.cer" -keystore "publicCerts.keystore" -storepass "pubwd123456"

项目配置

server:
  port: 8080
# License 相关配置
license:
  # 主题
  subject: license_demo
  # 公钥别称
  publicAlias: publicCert
  # 访问公钥的密码
  storePass: pubwd123456
  # license 位置
  licensePath: E:/licenseTest/license.lic
  # licensePath: /root/license-test/license.lic
  # 公钥位置
  publicKeysStorePath: E:/licenseTest/publicCerts.keystore
  # publicKeysStorePath: /root/license-test/publicCerts.keystore

为客户生成 license 文件

  1. 将项目打包,然后部署到客户服务器(这里以一台 linux 服务器为例演示),项目配置文件如下:
server:
  port: 8080
# License 相关配置
license:
  # 主题
  subject: license_demo
  # 公钥别称
  publicAlias: publicCert
  # 访问公钥的密码
  storePass: pubwd123456
  # license 位置
  # licensePath: E:/licenseTest/license.lic
  licensePath: /root/license-test/license.lic
  # 公钥位置
  # publicKeysStorePath: E:/licenseTest/publicCerts.keystore
  publicKeysStorePath: /root/license-test/publicCerts.keystore

image 2. 可以看到第一次启动找不到证书文件,证书安装失败 3. 通过调用前面所写的接口 /license/getServerInfos,获取服务器硬件信息

{
    "ipAddress": [
        "10.42.1.0",
        "10.101.1.4",
        "10.42.1.1",
        "172.17.0.1"
    ],
    "macAddress": [
        "DE-9B-A2-3D-34-C0",
        "7C-C3-85-5F-A7-E1",
        "0A-58-0A-2A-01-01",
        "02-42-3A-E2-79-21"
    ],
    "cpuSerial": "54 06 05 00 FF FB EB BF",
    "mainBoardSerial": "2102311TUVCNJC000055"
}

image 3. 调用前面所写的接口 /license/generateLicense,生成 license 文件

{
    "subject":"license_demo",
    "privateAlias":"privateKey",
    "keyPass":"priwd123456",
    "storePass":"pubwd123456",
    "licensePath":"/root/license-test/license.lic",
    "privateKeysStorePath":"/root/license-test/privateKeys.keystore",
    "issuedTime":"2020-10-10 00:00:01",
    "expiryTime":"2021-10-09 23:59:59",
    "consumerType":"User",
    "consumerAmount":1,
    "description":"license demo",
    "licenseCheckModel":{
        "ipAddress":[
            "10.42.1.0",
            "10.101.1.4",
            "10.42.1.1",
            "172.17.0.1"
        ],
        "macAddress":[
            "DE-9B-A2-3D-34-C0",
            "7C-C3-85-5F-A7-E1",
            "0A-58-0A-2A-01-01",
            "02-42-3A-E2-79-21"
        ],
        "cpuSerial":"54 06 05 00 FF FB EB BF",
        "mainBoardSerial":"2102311TUVCNJC000055"
    }
}

请求成功后会在设置的 licensePath 目录下生成一个 license.lic 文件

image 4. 重新启动服务,证书安装成功

image

证书有效性校验

为了方便调试,直接在本地运行了,验证证书有效性代码如下(实际生产中,需要在项目代码多处关键位置埋点,校验证书的有效性):

package com.example.demo;

import com.example.demo.license.LicenseVerify;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class TrueLicenseApplicationTests {
    private LicenseVerify licenseVerify;

    @Autowired
    public void setLicenseVerify(LicenseVerify licenseVerify) {
        this.licenseVerify = licenseVerify;
    }

    @Test
    void contextLoads() {
        System.out.println("licese是否有效:" + licenseVerify.verify());
    }
}
  1. 在创建证书的情况下,运行证书校验单元测试,打印证书无效的信息

image 2. 直接将前文在服务器上生成的证书下载到本地,启动项目,打印证书无效的信息(安装证书前会校验,IP地址、MAC 地址、CPU 序列号等前文设置的校验参数,防止证书复制翻版)

image 3. 重复上述证书创建安装过程后,再次运行证书校验单元测试,证书有效,测试通过
