Demand introduction

When we need to be right SpringBoot When encrypting the information in the configuration file of the project , Such as database password, etc , Now we can use it Jasypt To achieve .

Solution

First step , introduce Jasypt rely on

<dependency>    <groupId>com.github.ulisesbocchio</groupId>    <artifactId>jasypt-spring-boot-starter</artifactId>    <version>2.0.0</version></dependency>

The second step , Write a tool class

JasyptUtils：

package com.keafmd.springdemo.utils;import org.jasypt.encryption.pbe.PooledPBEStringEncryptor;import org.jasypt.encryption.pbe.StandardPBEByteEncryptor;import org.jasypt.encryption.pbe.config.SimpleStringPBEConfig;/** * Keafmd * * @ClassName: JasyptUtils * @Description: * @author:  Cowherd Conan  * @date: 2022-04-25 11:18 */public class JasyptUtils {    /** * Jasypt Generate encrypted results  * * @param password  The encryption password set in the configuration file  jasypt.encryptor.password * @param value  Value to be encrypted  * @return */    public static String encryptPwd(String password, String value) {        PooledPBEStringEncryptor encryptOr = new PooledPBEStringEncryptor();        encryptOr.setConfig(cryptOr(password));        String result = encryptOr.encrypt(value);        return result;    }    /** *  Decrypt  * * @param password  The encryption password set in the configuration file  jasypt.encryptor.password * @param value  Ciphertext to be decrypted  * @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) {        //  encryption         //  Replace the salt value with your familiar password , This password is the decryption key , It needs to be kept properly .        //  The salt value also needs to be written into the configuration file in the third step         System.out.println(encryptPwd("keafmd", "123456"));    }}

The third step , Modify the configuration file

• Write the salt value into the configuration file
• Replace the plaintext password with the ciphertext generated by the tool class , And use ENC(） Wrapped

eg：

#  Connect to data source spring:  datasource:    username: root    password: ENC(aXcmM77CmYgj67mBxQgI2A==)    url: jdbc:mysql://XXXX:XX/tt?useUnicode=true&characterEncoding=UTF-8&useSSL=false    jasypt:  encryptor:    password: keafmd

The above is the configuration file encryption （Jasypt Simple use ） The whole content of
