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

5.测试

  启动服务端和客户端访问。
