springboot使用jasypt加密敏感数据

jasypt 官网：
https://github.com/ulisesbocchio/jasypt-spring-boot

pom：

    com.github.ulisesbocchio
    jasypt-spring-boot-starter
    2.0.0

yml配置文件中引入密钥，也就是盐，加强加密的安全性：

# 配置文件加密key
jasypt:
  encryptor:
    password: panther

创建JasyptUtils 工具包：

package com.xxx.xxx.xxx;

import org.jasypt.encryption.pbe.PooledPBEStringEncryptor;
import org.jasypt.encryption.pbe.StandardPBEByteEncryptor;
import org.jasypt.encryption.pbe.config.SimpleStringPBEConfig;

public class JasyptUtils {
     

    /**

     *
     * @param password 配置文件中设定的加密密码 jasypt.encryptor.password

    public static String encryptPwd(String password, String value) {
     
        PooledPBEStringEncryptor encryptOr = new PooledPBEStringEncryptor();
        encryptOr.setConfig(cryptOr(password));
        String result = encryptOr.encrypt(value);
        return result;
    }

    /**

     * @return
     */
    public static String decyptPwd(String password, String value) {
     
        PooledPBEStringEncryptor encryptOr = new PooledPBEStringEncryptor();
        encryptOr.setConfig(cryptOr(password));
        String result = encryptOr.decrypt(value);
        return result;
    }

    /**
     * @param password salt
     * @return
     */
    public static SimpleStringPBEConfig cryptOr(String password) {
     
        SimpleStringPBEConfig config = new SimpleStringPBEConfig();
        config.setPassword(password);
        config.setAlgorithm(StandardPBEByteEncryptor.DEFAULT_ALGORITHM);
        config.setKeyObtentionIterations("1000");
        config.setPoolSize("1");
        config.setProviderName(null);
        config.setSaltGeneratorClassName("org.jasypt.salt.RandomSaltGenerator");
        config.setStringOutputType("base64");
        return config;
    }

    public static void main(String[] args) {
     
        // 加密
        System.out.println(encryptPwd("EbfYkitulv73I2p0mXI50JMXoaxZTKJ7", "root@1234"));
        // 解密
//        mysql@1234
//        System.out.println(decyptPwd("EbfYkitulv73I2p0mXI50JMXoaxZTKJ7", "bgWQ4OfVCUJ1ExsqNhGV+KKBgpx8alv+"));

//        root@1234
//        System.out.println(decyptPwd("EbfYkitulv73I2p0mXI50JMXoaxZTKJ7", "tdHzge8YvviOJaiV/+P6uQ9wgB44D1aH"));
    }

}

使用：

运行main方法，填入配置的盐，然后填入需要加密的value，直接运行即可。

加密结果：

# 开发环境
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/panther_dev?useUnicode=true&characterEncoding=UTF-8
    # Jasypt加密 可到common包中找到JasyptUtil加解密工具类生成加密结果 格式为ENC(加密结果)
    username: ENC(S2G86yhb0OMJMeNXUaGwYw==)
    password: ENC(GfP4qfnrJeqMvzN1nOemIQ==)
