非对称加密
一、什么是非对称加密(Asymmetric encryption)
二、Java-keytool 使用说明
非对称加密我们需要生成对应的公钥和私钥，jdk中提供的有java-keytool工具帮助我们生成，执行如下命令:
keytool -genkeypair -alias "config-info" -keyalg "RSA" -keystore c:\tools\encryp-info.keystore
三、创建服务项目
1.创建项目
创建一个SpringCloud项目
2.pom文件
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.13.RELEASE</version> </parent> <groupId>com.bobo</groupId> <artifactId>config-server-encryption-SRA</artifactId> <version>0.0.1-SNAPSHOT</version> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Dalston.SR1</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-config-server</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
3.配置文件
spring.application.name=config-server-encryption-SRA server.port=9060 #设置服务注册中心地址，指向另一个注册中心 eureka.client.serviceUrl.defaultZone=http://dpb:123456@eureka1:8761/eureka/,http://dpb:123456@eureka2:8761/eureka/ #Git 配置 spring.cloud.config.server.git.uri=https://gitee.com/dengpbs/config #spring.cloud.config.server.git.username= #spring.cloud.config.server.git.password= #keytool -genkeypair -alias "config-info" -keyalg "RSA" -keystore c:\tools\encryp-info.keystore # keystore 文件的路径 encrypt.key-store.location=classpath:encryp-info.keystore # alias 指定密钥对的别名，该别名是公开的; encrypt.key-store.alias=config-info # storepass 密钥仓库 encrypt.key-store.password=123456 # keypass 用来保护所生成密钥对中的私钥 encrypt.key-store.secret=123456
将生成的keystore文件拷贝到classpath目录下
4.启动测试
测试加密状态:http://localhost:9060/encrypt/status
加密
public class Test1 { /** * 通过RestTemplate来加密数据 * @param args */ public static void main(String[] args) { String url = "http://127.0.0.1:9060/encrypt"; RestTemplate template = new RestTemplate(); ResponseEntity<String> msg = template.postForEntity(url, "123456", String.class); System.out.println(msg.getBody()); } }
四、创建客户端项目
1.创建项目
拷贝上个案例的客户端程序。
2.pom文件
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.13.RELEASE</version> <relativePath /> <!-- lookup parent from repository --> </parent> <groupId>com.bobo</groupId> <artifactId>config-e-book-product-provider-sra</artifactId> <version>0.0.1-SNAPSHOT</version> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.4</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.47</version> </dependency> <dependency> <groupId>com.bobo</groupId> <artifactId>e-book-product-service</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-config</artifactId> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Dalston.SR5</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
3.bootstrap文件
spring.application.name=config-e-book-product-provider-sra server.port=9001 #\u8BBE\u7F6E\u670D\u52A1\u6CE8\u518C\u4E2D\u5FC3\u5730\u5740\uFF0C\u6307\u5411\u53E6\u4E00\u4E2A\u6CE8\u518C\u4E2D\u5FC3 eureka.client.serviceUrl.defaultZone=http://dpb:123456@eureka1:8761/eureka/,http://dpb:123456@eureka2:8761/eureka/ #配置中心服务端的链接信息 #默认 false,这里设置 true,表示开启读取配置中心的配置 spring.cloud.config.discovery.enabled=true #对应 eureka 中的配置中心 serviceId，默认是 configserver spring.cloud.config.discovery.serviceId=config-server-encryption-SRA #git 标签 spring.cloud.config.label=master
4.仓库文件
在git中创建config-e-book-product-provider-sra.properties文件
#--------------db---------------- mybatis.type-aliases-package=com.book.product.pojo mybatis.mapper-locations=classpath:com/bobo/product/mapper/*.xml spring.datasource.driverClassName=com.mysql.jdbc.Driver spring.datasource.url=jdbc:mysql://localhost:3306/book-product?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull spring.datasource.username={cipher}AQBTQaUuvTsXQ9Y4tr9Vq5BrEASk7ItrtNsQemtjgMd8anL5bMeo+NJVJ2kEKOzEdITiEGAguUTs78I9XGBZNI2DaNcySNjmKIi6NRX9ury1Fd9tGzT4ViZyNf2IcaUhwb7Yx0HBiHAyOxVDB1wStCUTUj3sD7/MZxw3VQeUMueti4j7giyHg2xGnKW1NnKNxKjpiUKY1uz3Ag2DZwdLQnAvmm90Y290HNNMDzq8ROrHbxXmyGCAlpmHXWloLZ0r7eBNkLvG7Hnnx9vDmWWyiRxSPiJo2UszmnKf5vN8hQZYIU83AjXMkOGolpPkOhg4nsoQS9++oF/AYGGydthxmuI9zsX8L6JXWBioo72yAXX8sw7doAp71ABuv2ivwd8njo8= spring.datasource.password={cipher}AQBZKEptQk2RBf+3DJ1tlHbmFKiuNtjwIbq8qf1kjIkkteYmxcrTfPmO5DYFuRd/xsVlKAfK+pfsn1nPntBjqMQYPvDPMy7LkcYe/gA4Q8/9d97Fn8o0TRv3VcYLvnPbn77S3CWBG/80LngQjLSbpShrUJdf7saC1ksBFDTmLMjlClJudIv3SpzkEVWZ8gc/UJoJSCHT/p3IAIxIGG6zQwYxv04tHYzMV+mxy5bgg6G6K+tQ9RShd0KkedtJHKTWaF3fJWfQHgy4eK5+d4UCinUso0pQg+kQpEgcszgK4+2jOnmf5O0OYzlzUkdAhYvqHFvi6qzQSh63KRTvkxAXSWZK6H8ku11Il3zJzNkiaJTK4bIFDKjV4ZSUbluzNxA946M=
5.测试
启动服务端和客户端访问。
直接访问服务端查看:http://localhost:9060/config-e-book-product-provider-SRA/default
我们发现当我们知道服务端的访问地址后，其实可以拿到解密后的明文，这种是我们加密中的漏铜，这时我们可以通过添加安全认证来解决。
五、安全认证
服务端项目集成Security
添加security依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency>
修改配置
在application.properties中添加如下信息
# 安全认证 #开启基于 http basic 的安全认证 security.basic.enabled=true security.user.name=dpb security.user.password=123456
测试
http://localhost:9060/config-e-book-product-provider-SRA/default
客户端认证
因为服务端开启了完全认证，所以客户端也必然要响应的添加。所以在bootstrap.properties中添加对应的账号信息即可:
spring.application.name=config-e-book-product-provider-sra server.port=9001 #\u8BBE\u7F6E\u670D\u52A1\u6CE8\u518C\u4E2D\u5FC3\u5730\u5740\uFF0C\u6307\u5411\u53E6\u4E00\u4E2A\u6CE8\u518C\u4E2D\u5FC3 eureka.client.serviceUrl.defaultZone=http://dpb:123456@eureka1:8761/eureka/,http://dpb:123456@eureka2:8761/eureka/ #配置中心服务端的链接信息 #默认 false,这里设置 true,表示开启读取配置中心的配置 spring.cloud.config.discovery.enabled=true #对应 eureka 中的配置中心 serviceId，默认是 configserver spring.cloud.config.discovery.serviceId=config-server-encryption-SRA #git 标签 spring.cloud.config.label=master #安全保护 spring.cloud.config.username=dpb spring.cloud.config.password=123456
这样就堵住了加密后信息在服务端显示的漏洞咯
