[文章] SpringBoot配置文件加密处理
当我们使用一些第三方SDK或服务时，一般需要配置如密钥、授权码、AID等隐私信息，此外大多数人都有代码提交仓库的好习惯【是吧？】有时候会因为一些失误操作而将自己的隐私数据发布到gitee\github上，就完球了。我最近看了些博客，尝试了下使用Jasypt来保证配置文件的安全性首先导入maven包这里使用的新版3.0.4<dependency><groupId>com.github.ulisesbocchio</groupId><artifactId>jasypt-spring-boot-starter</artifactId><version>3.0.4</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-configuration-processor</artifactId><optional>true</optional></dependency>编写一个自己使用的加密解密的小工具packagecom.lyne.moyu.uc.utils;importorg.jasypt.encryption.pbe.PooledPBEStringEncryptor;importorg.jasypt.encryption.pbe.config.SimpleStringPBEConfig;/***Keafmd**@ClassName:JasyptUtils*@Description:*@date:2022-04-2511:18*/publicclassJasyptUtils{/***Jasypt生成加密结果**@parampassword配置文件中设定的加密密码jasypt.encryptor.password*@paramvalue待加密值*@return*/publicstaticStringencryptPwd(Stringpassword,Stringvalue){PooledPBEStringEncryptorencryptOr=newPooledPBEStringEncryptor();encryptOr.setConfig(cryptOr(password));Stringresult=encryptOr.encrypt(value);returnresult;}/***解密**@parampassword配置文件中设定的加密密码jasypt.encryptor.password*@paramvalue待解密密文*@return*/publicstaticStringdecyptPwd(Stringpassword,Stringvalue){PooledPBEStringEncryptorencryptOr=newPooledPBEStringEncryptor();encryptOr.setConfig(cryptOr(password));Stringresult=encryptOr.decrypt(value);returnresult;}/***@parampasswordsalt*@return*/publicstaticSimpleStringPBEConfigcryptOr(Stringpassword){SimpleStringPBEConfigconfig=newSimpleStringPBEConfig();config.setPassword(password);//3.0.4版自动解密默认加密算法是PBEWITHHMACSHA512ANDAES_256，//1.8及以下版本可能需要自己替换安全文件，也可以在配置实体时修改config.setAlgorithm("PBEWITHHMACSHA512ANDAES_256");config.setKeyObtentionIterations("1000");config.setPoolSize("1");config.setProviderName("SunJCE");config.setSaltGeneratorClassName("org.jasypt.salt.RandomSaltGenerator");config.setIvGeneratorClassName("org.jasypt.iv.RandomIvGenerator");config.setStringOutputType("base64");returnconfig;}publicstaticvoidmain(String[]args){//加密//盐值替换成自己熟悉的口令，此口令为解密密钥，需要妥善保管。//盐值也需要在第三步写入配置文件System.out.println(encryptPwd("yoursalt","123456"));}}使用加密的后的密文在配置文件中使用EMC()函数和生成的密文替换你的敏感数据,，同时声明你的jasypt密钥这里演示mysql的密码spring:application:name:u-centerprofiles:active:devjackson:date-format:yyyy-MM-ddHH:mm:sstime-zone:GMT+8mvc:throw-exception-if-no-handler-found:truestatic-path-pattern:/**web:resources:add-mappings:falsedatasource:url:jdbc:mysql://localhost:3306/mo_yu_ucenter?userUnicode=true&useSSL=false&serverTimezone=Asia/Shanghai&characterEncoding=utf-8&allowPublicKeyRetrieval=truedriver-class-name:com.mysql.cj.jdbc.Drivertype:com.alibaba.druid.pool.DruidDataSourceusername:rootpassword:ENC(lG4hT3FdNsFdWPmUCob7D4YUHZqyaSXEH/uYzfAWh58lSVwBz6wLd02jSgXbNHzH)jasypt:encryptor:password:yoursalt##优化加密密钥在配置文件中声明加密密码等于脱裤子放屁，这样之前的操作等于没做我的思路的是将jasypt密码存放在一个新的配置文件中，在你提交到仓库时将该文件忽略或删除，以保证密码本地可知。在资源目录下创建一个配置文件来存放密码jasypt.propertiesjasypt.password=yoursalt创建一个配置实体来读取配置文件/***@authorlyne*@date2022/11/28*/@Component@PropertySource("classpath:jasypt.properties")@ConfigurationProperties(prefix="jasypt")publicclassJasyptProperties{privateStringpassword;publicStringgetPassword(){returnpassword;}publicvoidsetPassword(Stringpassword){this.password=password;}}重写jasyptStringEncryptor/***@authorlyne*@date2022/11/28*/@ConfigurationpublicclassJasyptConfig{@AutowiredprivateJasyptPropertiesmyJasyptProperties;@Bean("jasyptStringEncryptor")publicStringEncryptorjasyptStringEncryptor(Singleton<JasyptEncryptorConfigurationProperties>configProps){PooledPBEStringEncryptorencryptor=newPooledPBEStringEncryptor();JasyptEncryptorConfigurationPropertiesjasyptProperties=configProps.get();SimpleStringPBEConfigconfig=newSimpleStringPBEConfig();config.setPassword(myJasyptProperties.getPassword());config.setAlgorithm(jasyptProperties.getAlgorithm());config.setKeyObtentionIterations(jasyptProperties.getKeyObtentionIterations());config.setPoolSize(jasyptProperties.getPoolSize());config.setProviderName(jasyptProperties.getProviderName());config.setSaltGeneratorClassName(jasyptProperties.getSaltGeneratorClassname());config.setIvGeneratorClassName(jasyptProperties.getIvGeneratorClassname());config.setStringOutputType(jasyptProperties.getStringOutputType());encryptor.setConfig(config);returnencryptor;}}修改.gitignore.DS_Storematerial-ui/node_modules/distlogs#Compiledclassfile*.classtarget/test/test#Logfile*.log#localenvfiles.env.local.env.*.local#Logfilesnpm-debug.log*yarn-debug.log*yarn-error.log*pnpm-debug.log*#Editordirectoriesandfiles.idea.vscode*.suo*.ntvs**.njsproj*.sln*.sw?*.jar*.war*.nar*.ear*.zip*.tar.gz*.rar*.iml#virtualmachinecrashlogs,seehttp://www.java.com/en/download/help/error_hotspot.xmlhs_err_pid*#privacyFilesjasypt.propertiesover
