# 非对称加密 #

## 一、什么是非对称加密(Asymmetric encryption) ##

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9kcGItYm9ib2thb3lhLXNtLmJsb2cuY3Nkbi5uZXQ_size_16_color_FFFFFF_t_70]

## 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 ##

## 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

### 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。

## 5.测试 ##

启动服务端和客户端访问。

![在这里插入图片描述][20190626234800526.png]

直接访问服务端查看:[http://localhost:9060/config-e-book-product-provider-SRA/default][http_localhost_9060_config-e-book-product-provider-SRA_default]

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9kcGItYm9ib2thb3lhLXNtLmJsb2cuY3Nkbi5uZXQ_size_16_color_FFFFFF_t_70 9]

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][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:

这样就堵住了加密后信息在服务端显示的漏洞咯
