  1. 2019.09.17 [spring] spring cloud config 사용시 암호 관련 예시


spring cloud config 사용시 사용자 이름, 패스워드를 입력한다


"java -jar config-server.jar --spring.cloud.config.server.git.username=knight76 --spring.cloud.config.server.git.password=1234"


아니면 프로퍼티(property) 설정을 추가한다.


spring.cloud.config.server.git.username=knight76

spring.cloud.config.server.git.password=1234




패스워드가 나타나는 게 꺼림직하다.

jasypt(com.github.ulisesbocchio:jasypt-spring-boot-starter) 라이브러리를 사용하면 암호화를 할수 있다.


gradle 설정에  jasypt(com.github.ulisesbocchio:jasypt-spring-boot-starter) 라이브러리를  추가한다.

dependencies {
implementation 'org.springframework.cloud:spring-cloud-config-server'
implementation 'org.springframework.cloud:spring-cloud-starter-config'
compile 'com.github.ulisesbocchio:jasypt-spring-boot-starter:2.1.2'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
}


application.properties에 


server.port=8080
jasypt.encryptor.bean=jasyptStringEncryptor

management.endpoint.env.enabled=true
management.endpoints.web.exposure.include=*

spring.cloud.config.server.bootstrap=true
spring.cloud.config.server.git.uri=https://github.com/knight76/spring-cloud-config-example
spring.cloud.config.server.git.timeout=5
spring.cloud.config.server.git.username=knight76
spring.cloud.config.server.git.password=123214



암호화에 사용되는 JasyptConfig 클래스를 추가한다. 


package com.github.knight76.config.configserver;

import org.jasypt.encryption.StringEncryptor;
import org.jasypt.encryption.pbe.PooledPBEStringEncryptor;
import org.jasypt.encryption.pbe.config.SimpleStringPBEConfig;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class JasyptConfig {

final static String KEY = "knight76";

final static String ALGORITHM = "PBEWithMD5AndDES";

@Bean("jasyptStringEncryptor")
public StringEncryptor stringEncryptor() {
PooledPBEStringEncryptor encryptor = new PooledPBEStringEncryptor();
SimpleStringPBEConfig config = new SimpleStringPBEConfig();
config.setPassword(KEY);
config.setAlgorithm(ALGORITHM);
config.setKeyObtentionIterations("1000");
config.setPoolSize("1");
config.setProviderName("SunJCE");
config.setSaltGeneratorClassName("org.jasypt.salt.RandomSaltGenerator");
config.setStringOutputType("base64");
encryptor.setConfig(config);
return encryptor;
}

}


 테스트 코드는 다음과 같다. 테스트 코드의 비밀번호를 사용한다. 

package com.github.knight76.config.configserver;

import org.jasypt.encryption.pbe.StandardPBEStringEncryptor;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class ConfigServerApplicationTests {

@Test
public void test() {
StandardPBEStringEncryptor standardPBEStringEncryptor = new StandardPBEStringEncryptor();
standardPBEStringEncryptor.setAlgorithm(JasyptConfig.ALGORITHM);
standardPBEStringEncryptor.setPassword(JasyptConfig.KEY);

String enc = standardPBEStringEncryptor.encrypt("비밀번호");
System.out.println("enc = " + enc);

String des = standardPBEStringEncryptor.decrypt(enc);
System.out.println("des = " + des);
}
}



테스트 코드를 통해 얻은 비밀번호를 application.properties의 비밀번호로 설정한다. ENC(..비밀번호..)로 적용한다.


server.port=8080
jasypt.encryptor.bean=jasyptStringEncryptor

management.endpoint.env.enabled=true
management.endpoints.web.exposure.include=*

spring.cloud.config.server.bootstrap=true
spring.cloud.config.server.git.uri=https://github.com/knight76/spring-cloud-config-example
spring.cloud.config.server.git.timeout=5
spring.cloud.config.server.git.username=knight76
spring.cloud.config.server.git.password=ENC(암호문)


풀 예제 코드는 다음과 같다.

이 방식 외에 RSA 비밀 키를 사용하는 방식이 있다.
