非對稱加密

一、什麼是非對稱加密(Asymmetric encryption)

二、Java-keytool 使用說明

  非對稱加密我們需要生成對應的公鑰和私鑰，jdk中提供的有java-keytool工具幫助我們生成，執行如下命令:

keytool -genkeypair -alias "config-info" -keyalg "RSA" -keystore c:\tools\encryp-info.keystore

三、建立服務專案

1.建立專案

  建立一個SpringCloud專案

2.pom檔案

            </plugin>
        </plugins>
    </build>
</project>
 

3.配置檔案

spring.application.name=config-server-encryption-SRA
server.port=9060
#設定服務註冊中心地址，指向另一個註冊中心
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 檔案的路徑
encrypt.key-store.location=classpath:encryp-info.keystore
# alias 指定金鑰對的別名，該別名是公開的;
encrypt.key-store.alias=config-info
# storepass 金鑰倉庫
encrypt.key-store.password=123456
# keypass 用來保護所生成金鑰對中的私鑰
encrypt.key-store.secret=123456
 

將生成的keystore檔案拷貝到classpath目錄下

4.啟動測試

測試加密狀態:http://localhost:9060/encrypt/status

加密

public class Test1 {

    /**
     * 通過RestTemplate來加密資料
     * @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、建立客戶端專案

1.建立專案

  拷貝上個案例的客戶端程式。
