Jasypt Spring Boot 为 Spring Boot 应用中的属性值提供加密支持。
Reference
1. 添加 Maven 依赖
<!-- jasypt -->
<dependency>
<groupId>com.github.ulisesbocchio</groupId>
<artifactId>jasypt-spring-boot-starter</artifactId>
<version>3.0.5</version>
</dependency>
2. 添加 jasypt 密码加密配置
# jasypt 密码加密配置
jasypt:
encryptor:
# 加密盐值
password: jasypt
# 加密算法设置 3.0.0 以后需要加上下面两个配置
algorithm: PBEWithMD5AndDES
iv-generator-classname: org.jasypt.iv.NoIvGenerator
3. 手动加密/解密工具类
import org.jasypt.encryption.pbe.PooledPBEStringEncryptor;
import org.jasypt.encryption.pbe.config.SimpleStringPBEConfig;
public class JasyptUtil {
/**
* Jasypt生成加密结果
* @param password 配置文件中设定的加密盐值
* @param value 加密值
* @return
*/
public static String encyptPwd(String password,String value){
PooledPBEStringEncryptor encryptor = new PooledPBEStringEncryptor();
encryptor.setConfig(cryptor(password));
String result = encryptor.encrypt(value);
return result;
}
/**
* 解密
* @param password 配置文件中设定的加密盐值
* @param value 解密密文
* @return
*/
public static String decyptPwd(String password,String value){
PooledPBEStringEncryptor encryptor = new PooledPBEStringEncryptor();
encryptor.setConfig(cryptor(password));
String result = encryptor.decrypt(value);
return result;
}
public static SimpleStringPBEConfig cryptor(String password){
SimpleStringPBEConfig config = new SimpleStringPBEConfig();
config.setPassword(password);
config.setAlgorithm("PBEWithMD5AndDES");
config.setKeyObtentionIterations("1000");
config.setPoolSize("1");
config.setProviderName("SunJCE");
config.setSaltGeneratorClassName("org.jasypt.salt.RandomSaltGenerator");
config.setStringOutputType("base64");
return config;
}
public static void main(String[] args) {
// 加密
String encPwd = encyptPwd("jasypt", "123456");
// 解密
String decPwd = decyptPwd("jasypt", encPwd);
System.out.println(encPwd);
System.out.println(decPwd);
}
}
4. 修改配置中的明文密码
用官方提供的保留字 ENC
,将加密的密码包裹即可
spring:
datasource:
url: jdbc:mysql://xx.xx.xx.xx/xxxx?useUnicode=true&characterEncoding=utf8&useSSL=false
username: root
password: ENC(加密后的密码)
driver-class-name: com.mysql.cj.jdbc.Driver
5. 加密结果与加密盐值隔离
加密盐值不应该直接放在代码中,容易造成开发人员泄露数据安全性
服务器中配置,同理将 Java 启动虚拟机参数新增配置,这样我们密码盐值就放在了服务器中,就不会造成加密盐值泄漏了
