1. 前景
在使用Springboot时,通常很多信息都是在application.yml中直接明文配置的,比如数据库链接信息,redis链接信息等等。有些公司的场景可能需要对配置文件进行加密,防止部署操作人员接触数据句的重要信息,所以需要对敏感数据进行加密。
Jasypt这个库为我们解决了这个问题,实现了springboot配置的自定义加密加密。
2. 开源项目介绍

2.2 配置application信息
jasypt配置
jasypt: encryptor: # 加密算法 algorithm: PBEWITHHMACSHA512ANDAES_256 # 加密使用的盐 password: jaspyt_password
2.3 加密解密测试
/** * @author HLH * @description: 加密解密测试 */ @SpringBootTest @RunWith(SpringRunner.class) public class JasyptTest { @Autowired private StringEncryptor stringEncryptor; /** * 加密解密测试 */ @Test public void jasyptTest() { // 加密 System.out.println(stringEncryptor.encrypt("root")); // JSrINYe4IBotHndGjX1hnmY3mtPNUJlXjP12cx1+pHqUz2FNXGPu3Frnajh3QCXg // 解密 System.out.println(stringEncryptor.decrypt("JSrINYe4IBotHndGjX1hnmY3mtPNUJlXjP12cx1+pHqUz2FNXGPu3Frnajh3QCXg")); // root } /** * 手动测试 */ @Test public void test() { PooledPBEStringEncryptor encryptor = new PooledPBEStringEncryptor(); SimpleStringPBEConfig config = new SimpleStringPBEConfig(); config.setPassword("jaspyt_password"); 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"); encryptor.setConfig(config); System.out.println(encryptor.encrypt("root")); // JSrINYe4IBotHndGjX1hnmY3mtPNUJlXjP12cx1+pHqUz2FNXGPu3Frnajh3QCXg } }
3. 使用Jasypt加密后的字符串代替数据库密码
3.1 使用加密类进行加密
密码 root 加密之后
XjYnpGd3JGICnxumpFcfRP8J83m265yC/r1FiwLr9Yo1PNbPXQ2xykLHPpy02CZ1
/** * 数据库密码加密 */ @Test public void encryptPasswored() { // 加密 System.out.println(stringEncryptor.encrypt("root")); // XjYnpGd3JGICnxumpFcfRP8J83m265yC/r1FiwLr9Yo1PNbPXQ2xykLHPpy02CZ1 // 解密 System.out.println(stringEncryptor.decrypt("XjYnpGd3JGICnxumpFcfRP8J83m265yC/r1FiwLr9Yo1PNbPXQ2xykLHPpy02CZ1")); // root }
3.2 替换数据库配置
spring: datasource: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://192.168.10.31/mp username: root # 使用ENC()包裹,标识为加密之后的,否则无法解密,会报错 password: ENC(R2H69h1aEgJ3EDPLXAVQ5CxZJWtl8EvqIJUtlATRt6om4w46/J+blu2JAvkR7Yvp)
3.3 测试
@Autowired private DataSource dataSource; /** * 测试加密之后的数据源使用是否正常 * 查看是否能正常获取链接 */ @Test public void datasourceTest() throws SQLException { Connection connection = dataSource.getConnection(); System.out.println(connection); // HikariProxyConnection@1487059223 wrapping com.mysql.cj.jdbc.ConnectionImpl@48904d5a connection.close(); }
4. Jasypt配置详解
所有配置都在
JasyptEncryptorConfigurationProperties类中定义,我们只需要在yml中配置属性,即可达到重写的目的
Jasypt使用StringEncryptor来解密属性。如果Spring上下文中找不到自定义的StringEncryptor,就会自动创建一个,可以通过以下属性进行配置
唯一需要的属性是加密的盐,其余的可以使用默认值。虽然所有这些属性都可以在属性文件中生命,但加密所使用的盐不应该存储在属性文件中,而是应该通过系统属性、命令行参数或者环境变量传递,只要他的名称是jasypt.encryptor.password,它就可以工作。
倒数第二个属性
jasypt.encryptor.proxyPropertySources用于只是jasypt spring boot如何拦截属性值进行解密。默认值false使用PropertySource、EnumerablePropertySource和MapPropertySource的自定义包装器实现。当为true时,拦截机制将在每个特定的PropertySource实现上使用CGLib代理。在某些必须保留原始PropertySource类型的场景中,这可能很有用。
5. 自定义加密
默认情况下,bean容器会配置LazyJasyptSringEncryptor
5.1 官方配置
官方配置的Bean都是在
EncryptablePropertyResolverConfiguration中进行注入的
@Bean( name = {"lazyJasyptStringEncryptor"} ) public StringEncryptor stringEncryptor(EnvCopy envCopy, BeanFactory bf) { String customEncryptorBeanName = envCopy.get().resolveRequiredPlaceholders(ENCRYPTOR_BEAN_PLACEHOLDER); boolean isCustom = envCopy.get().containsProperty("jasypt.encryptor.bean"); return new DefaultLazyEncryptor(envCopy.get(), customEncryptorBeanName, isCustom, bf); }
5.2 自定义加密
可以在Spring上下文中共自定义自己的StringEncryptor Bean,默认的加密程序将被忽略
注意
自定义Bean的名称必须为 jasyptStringEncryptor,否则解密不生效
自定义注入bean
/** * 加入 StringEncryptor 加密解密类 * beanName 必须为 jasyptStringEncryptor 才能是自定义的生效 * configProps 为jasypt框架中读取的配置类,就不用自己读取了 */ @Bean("jasyptStringEncryptor") public StringEncryptor jasyptStringEncryptor(Singleton<JasyptEncryptorConfigurationProperties> configProps) { PooledPBEStringEncryptor encryptor = new PooledPBEStringEncryptor(); JasyptEncryptorConfigurationProperties jasyptProperties = configProps.get(); SimpleStringPBEConfig config = new SimpleStringPBEConfig(); config.setPassword(jasyptProperties.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); return encryptor; }
6. 自定义属性探测器
属性探测器为判断一个属性值是否为加密后的字符串,并且截取真实字符串
6.1 官方处理流程
6.1.2 注入
在
EncryptablePropertyResolverConfiguration类中
@Bean( name = {"lazyEncryptablePropertyDetector"} ) public EncryptablePropertyDetector encryptablePropertyDetector(EnvCopy envCopy, BeanFactory bf) { String customDetectorBeanName = envCopy.get().resolveRequiredPlaceholders(DETECTOR_BEAN_PLACEHOLDER); boolean isCustom = envCopy.get().containsProperty("jasypt.encryptor.property.detector-bean"); return new DefaultLazyPropertyDetector(envCopy.get(), customDetectorBeanName, isCustom, bf); }
6.1.2 DefaultLazyPropertyDetector
默认实现是
DefaultLazyPropertyDetector,具体代码是
@Slf4j public class DefaultLazyPropertyDetector implements EncryptablePropertyDetector { // 属性探测器 private Singleton<EncryptablePropertyDetector> singleton; public DefaultLazyPropertyDetector(ConfigurableEnvironment environment, String customDetectorBeanName, boolean isCustom, BeanFactory bf) { singleton = new Singleton<>(() -> Optional.of(customDetectorBeanName) .filter(bf::containsBean) .map(name -> (EncryptablePropertyDetector) bf.getBean(name)) .map(tap(bean -> log.info("Found Custom Detector Bean {} with name: {}", bean, customDetectorBeanName))) .orElseGet(() -> { if(isCustom) { throw new IllegalStateException(String.format("Property Detector custom Bean not found with name '%s'", customDetectorBeanName)); } log.info("Property Detector custom Bean not found with name '{}'. Initializing Default Property Detector", customDetectorBeanName); return createDefault(environment); })); } public DefaultLazyPropertyDetector(ConfigurableEnvironment environment) { // 创建一个属性探测器 singleton = new Singleton<>(() -> createDefault(environment)); } private DefaultPropertyDetector createDefault(ConfigurableEnvironment environment) { // 读取所有的属性 JasyptEncryptorConfigurationProperties props = JasyptEncryptorConfigurationProperties.bindConfigProps(environment); // 创建一个默认的属性探测器,读取配置文件中的前缀和后缀 return new DefaultPropertyDetector(props.getProperty().getPrefix(), props.getProperty().getSuffix()); } /** * 是否为解密格式字符串 */ @Override public boolean isEncrypted(String property) { return singleton.get().isEncrypted(property); } /** * 获取真是的加密后的字符串 */ @Override public String unwrapEncryptedValue(String property) { return singleton.get().unwrapEncryptedValue(property); } }
在其中是创建了一个DefaultPropertyDetector对象
6.1.3 DefaultPropertyDetector
public class DefaultPropertyDetector implements EncryptablePropertyDetector { // 默认前缀和后缀 private String prefix = "ENC("; private String suffix = ")"; public DefaultPropertyDetector() { } public DefaultPropertyDetector(String prefix, String suffix) { Assert.notNull(prefix, "Prefix can't be null"); Assert.notNull(suffix, "Suffix can't be null"); this.prefix = prefix; this.suffix = suffix; } @Override public boolean isEncrypted(String property) { if (property == null) { return false; } final String trimmedValue = property.trim(); return (trimmedValue.startsWith(prefix) && trimmedValue.endsWith(suffix)); } // 去掉前缀和后缀 @Override public String unwrapEncryptedValue(String property) { return property.substring( prefix.length(), (property.length() - suffix.length())); } }
6.2 自定义规则探测器
两种方式自定义
- 提供一个名为encryptablePropertyDetector的EncryptablePropertyDetector类型的Bean来覆盖默认的实现
- 如果提供的bean名称不为encryptablePropertyDetector,可以通过修改yml中的属性jasypt.encryptor.property.detector-Bean为自己的bean的名称。
方式
- 要么自定义类
- 要么修改yml中的前缀和后缀
6.2.1 自定义属性探测器,加入容器
/** * 自定义属性探测器 * beanName为 encryptablePropertyDetector */ @Bean(name = "encryptablePropertyDetector") public EncryptablePropertyDetector encryptablePropertyDetector() { return new MyEncryptablePropertyDetector(); } /** * @author HLH * @description: 自定义的属性探测器 * @email [email protected] * @date : Created in 2021/8/19 20:01 */ public class MyEncryptablePropertyDetector implements EncryptablePropertyDetector { /** * 是否为可以解密的字符串 * @param value 全部的字符串 * @return 是否是解密的字符串,true,是,false,否 */ @Override public boolean isEncrypted(String value) { if (value != null) { return value.startsWith("ENC@"); // 自定义规则为 ENC@开头 } return false; } /** * 截取到除了标识之后的值 * @param value 带前缀 * @return string 去掉标识符的字符串 */ @Override public String unwrapEncryptedValue(String value) { return value.substring("ENC@".length()); // 截取ENC@之后的字符串 } }
jasypt: encryptor: # 加密算法 algorithm: PBEWITHHMACSHA512ANDAES_256 # 加密使用的盐 password: jaspyt_password property: # 修改默认的前缀和后缀,如果自定义属性探测器,那么此项配置不起作用 # prefix: ENC_( # suffix: ) # 自定义的属性探测器,如果这个是自定义的,那么上述的前缀后缀不生效 detector-bean: encryptablePropertyDetector
yml中的配置
6.2.2 修改yml中的配置
spring: datasource: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://192.168.10.31/mp username: root # 使用ENC()包裹,标识为加密之后的,否则无法解密,会报错 # 自定义规则之后,使用ENC@开头 password: ENC@JSrINYe4IBotHndGjX1hnmY3mtPNUJlXjP12cx1+pHqUz2FNXGPu3Frnajh3QCXg
7. 自定义规则的前缀和后缀
在上述说明中,在
DefaultLazyPropertyDetector中是默认是通过配置文件中的规则进行匹配的。默认规则是以ENC(开头,以)结尾,可以复写配置来自定义前缀和后缀
上面第6条是自定义了属性探测器,包括了定义规则和过滤字符串
如果只是想自定义前缀和后缀,那么可以直接修改yml中的配置来修改自定义的前缀和后缀
jasypt: encryptor: # 加密算法 algorithm: PBEWITHHMACSHA512ANDAES_256 # 加密使用的盐 password: jaspyt_password property: # 修改默认的前缀和后缀,如果自定义属性探测器,那么此项配置不起作用 prefix: ENC( suffix: )
8. 直接自定义解密规则
上述6和7自定义了解密字符串的规则和解密字符串的过滤,但是真正的解析处理还是Jasypt框架来负责的。我们也可以直接自定义解密的一系列流程。
8.1 官方处理流程
8.1.1 官方的注入
在
EncryptablePropertyResolverConfiguration类中
@Bean( name = {"lazyEncryptablePropertyResolver"} ) public EncryptablePropertyResolver encryptablePropertyResolver(@Qualifier("lazyEncryptablePropertyDetector") EncryptablePropertyDetector propertyDetector, @Qualifier("lazyJasyptStringEncryptor") StringEncryptor encryptor, BeanFactory bf, EnvCopy envCopy, ConfigurableEnvironment environment) { String customResolverBeanName = envCopy.get().resolveRequiredPlaceholders(RESOLVER_BEAN_PLACEHOLDER); boolean isCustom = envCopy.get().containsProperty("jasypt.encryptor.property.resolver-bean"); return new DefaultLazyPropertyResolver(propertyDetector, encryptor, customResolverBeanName, isCustom, bf, environment); }
默认注入的是
DefaultLazyPropertyResolver但是在其中创建的是
EncryptablePropertyResolver对象
8.1.2 EncryptablePropertyResolver
- 官方默认是通过EncryptablePropertyResolver接口来处理解析字符串的
public interface EncryptablePropertyResolver { /** * 处理所有属性的解密处理 * 如果为检测到加密规则,那么返回实际为相同的字符创 * * @param value 属性值 * @return 如果值未加密,返回原值,如果加密,返回加密之后的值 */ String resolvePropertyValue(String value); }
- 其真实性使用的实现类是DefaultPropertyResolver用来真正处理解析。就是通过调用上文中的StringEncryptor处理解密,使用EncryptablePropertyDetector定义的解密字符串规则定义是否为加密的字符串
public class DefaultPropertyResolver implements EncryptablePropertyResolver { private final Environment environment; // 默认的或者自定义的StringEncryptor,用来解密 private StringEncryptor encryptor; // 默认的或者自定义的EncryptablePropertyDetector,用来定义是否为加密的字符串 private EncryptablePropertyDetector detector; public DefaultPropertyResolver(StringEncryptor encryptor, Environment environment) { this(encryptor, new DefaultPropertyDetector(), environment); } public DefaultPropertyResolver(StringEncryptor encryptor, EncryptablePropertyDetector detector, Environment environment) { this.environment = environment; Assert.notNull(encryptor, "String encryptor can't be null"); Assert.notNull(detector, "Encryptable Property detector can't be null"); this.encryptor = encryptor; this.detector = detector; } @Override public String resolvePropertyValue(String value) { return Optional.ofNullable(value) .map(environment::resolvePlaceholders) .filter(detector::isEncrypted) // 如果经过属性探测器确认的,才继续 .map(resolvedValue -> { try { String unwrappedProperty = detector.unwrapEncryptedValue(resolvedValue.trim()); // 过滤加密规则后的字符串 String resolvedProperty = environment.resolvePlaceholders(unwrappedProperty); return encryptor.decrypt(resolvedProperty); // 解密 } catch (EncryptionOperationNotPossibleException e) { throw new DecryptionException("Unable to decrypt: " + value + ". Decryption of Properties failed, make sure encryption/decryption " + "passwords match", e); } }) .orElse(value); } }
8.2 自定义的解密逻辑
编写自己的解密逻辑类
加入spring容器,命名为
encryptablePropertyResolver,或者通过yml方式配置自定义bean名称
@Bean("encryptablePropertyResolver") public EncryptablePropertyResolver encryptablePropertyResolver( StringEncryptor jasyptStringEncryptor, EncryptablePropertyDetector encryptablePropertyDetector) { return new MyEncryptablePropertyResolver(jasyptStringEncryptor, encryptablePropertyDetector); } /** * @author HLH * @description: 直接自定义解密规则 * @email [email protected] * @date : Created in 2021/8/21 21:22 */ public class MyEncryptablePropertyResolver implements EncryptablePropertyResolver { // 处理解密 private final StringEncryptor encryptor; // 属性探测器 private final EncryptablePropertyDetector detector; public MyEncryptablePropertyResolver(StringEncryptor encryptor, EncryptablePropertyDetector detector) { this.encryptor = encryptor; this.detector = detector; } /** * 处理真正的解密逻辑 * @param value 原始值 * @return 如果值未加密,返回原值,如果加密,返回加密之后的值 */ @Override public String resolvePropertyValue(String value) { return Optional.ofNullable(value) .filter(detector::isEncrypted) // 如果经过属性探测器确认的,才继续 .map(resolvedValue -> { try { String unwrappedProperty = detector.unwrapEncryptedValue(resolvedValue.trim()); // 过滤加密规则后的字符串 return encryptor.decrypt(unwrappedProperty); // 解密 } catch (EncryptionOperationNotPossibleException e) { throw new DecryptionException("Unable to decrypt: " + value + ". Decryption of Properties failed, make sure encryption/decryption " + "passwords match", e); } }) .orElse(value); } }
yml配置
jasypt: encryptor: # 加密算法 algorithm: PBEWITHHMACSHA512ANDAES_256 # 加密使用的盐 password: jaspyt_password property: # 修改默认的前缀和后缀,如果自定义属性探测器,那么此项配置不起作用 # prefix: ENC_( # suffix: ) # 自定义的属性探测器,如果这个是自定义的,那么上述的前缀后缀不生效 detector-bean: encryptablePropertyDetector # 自定义解密逻辑类 如果配置了,默认的解析器将不工作 resolver-bean: encryptablePropertyResolver
9. 自定义过滤器
在Jasypt-spring-boot中,引入了过滤器
过滤器filter允许过滤某些属性,不进行解密。默认情况下,jasypt.encryptor开头的所有属性都会将从检查项中排除掉。这是为了配置Bean,在加载时循环依赖
9.1 默认处理流程
9.1.1 官方的注入
在
EncryptablePropertyResolverConfiguration类中
@Bean( name = {"lazyEncryptablePropertyFilter"} ) public EncryptablePropertyFilter encryptablePropertyFilter(EnvCopy envCopy, ConfigurableBeanFactory bf) { String customFilterBeanName = envCopy.get().resolveRequiredPlaceholders(FILTER_BEAN_PLACEHOLDER); boolean isCustom = envCopy.get().containsProperty("jasypt.encryptor.property.filter-bean"); return new DefaultLazyPropertyFilter(envCopy.get(), customFilterBeanName, isCustom, bf); }
于上面的逻辑一样,在DefaultLazyPropertyFilter中其实是新建了一个EncryptablePropertyFilter对象,默认实现类是DefaultPropertyFilter
9.1.2 DefaultPropertyFilter
public class DefaultPropertyFilter implements EncryptablePropertyFilter { // 过滤的和包含的,优先读取配置文件的 private final List<String> includeSourceNames; private final List<String> excludeSourceNames; private final List<String> includePropertyNames; private final List<String> excludePropertyNames; public DefaultPropertyFilter() { includeSourceNames = null; includePropertyNames = null; excludeSourceNames = null; excludePropertyNames = null; } public DefaultPropertyFilter(List<String> includeSourceNames, List<String> excludeSourceNames, List<String> includePropertyNames, List<String> excludePropertyNames) { this.includeSourceNames = includeSourceNames; this.excludeSourceNames = excludeSourceNames; this.includePropertyNames = includePropertyNames; this.excludePropertyNames = excludePropertyNames; } // 是否拦截 @Override public boolean shouldInclude(PropertySource<?> source, String name) { // 如果上述四个都没有配置,那么全部放行 if (isIncludeAll()) { return true; } // 如果是不包含的,返回false,就过滤掉了 if (isMatch(source.getName(), excludeSourceNames) || isMatch(name, excludePropertyNames)) { return false; } // 如果是包含的,就放行 return isIncludeUnset() || isMatch(source.getName(), includeSourceNames) || isMatch(name, includePropertyNames); } private boolean isIncludeAll() { return isIncludeUnset() && isExcludeUnset(); } private boolean isIncludeUnset() { return isEmpty(includeSourceNames) && isEmpty(includePropertyNames); } private boolean isExcludeUnset() { return isEmpty(excludeSourceNames) && isEmpty(excludePropertyNames); } private boolean isEmpty(List<String> patterns) { return patterns == null || patterns.isEmpty(); } // 传递的配置其实是正则,进行正则匹配 private boolean isMatch(String name, List<String> patterns) { return name != null && !isEmpty(patterns) && patterns.stream().anyMatch(name::matches); } }
9.2 自定义过滤器
方式
- 要么自定义过滤器
- 要么修改jasypt.encryptor.property.include-names或者jasypt.encryptor.property.exclude-names配置拦截和放行的资源key
自定义过滤器类
加入spring容器,命名为encryptablePropertyFilter
/** * 自定义的属性拦截器 * @param configProps Jasypt官方读取的配置集合 * @return 自定义属性拦截器 */ @Bean(name="encryptablePropertyFilter") public EncryptablePropertyFilter encryptablePropertyFilter( Singleton<JasyptEncryptorConfigurationProperties> configProps) { return new MyEncryptablePropertyFilter(configProps.get()); } /** * @author HLH * @description: 自定义的属性过滤器 * @email [email protected] * @date : Created in 2021/8/22 13:37 */ public class MyEncryptablePropertyFilter implements EncryptablePropertyFilter { /** jasypt 的所有配置*/ JasyptEncryptorConfigurationProperties jasyptProperties; public MyEncryptablePropertyFilter(JasyptEncryptorConfigurationProperties jasyptProperties) { this.jasyptProperties = jasyptProperties; } @Override public boolean shouldInclude(PropertySource<?> source, String name) { List<String> excludeNames = jasyptProperties.getProperty().getFilter().getExcludeNames(); List<String> includeNames = jasyptProperties.getProperty().getFilter().getIncludeNames(); if (CollectionUtils.isEmpty(includeNames) && CollectionUtils.isEmpty(excludeNames)) { return true; } if (isMatch(source.getName(), excludeNames) || isMatch(source.getName(), excludeNames)) { return false; } return CollectionUtils.isEmpty(includeNames) || isMatch(source.getName(), includeNames) || isMatch(name, includeNames); } /** * 正则判断,如果满足,返回true,如果不满足,返回false * @param name 配置的key * @param patterns 正则列表 * @return 如果满足,返回true,如果不满足,返回false */ private boolean isMatch(String name, List<String> patterns) { return name != null && !CollectionUtils.isEmpty(patterns) && patterns.stream().anyMatch(name::matches); } }
yml配置
jasypt: encryptor: # 加密算法 algorithm: PBEWITHHMACSHA512ANDAES_256 # 加密使用的盐 password: jaspyt_password property: # 修改默认的前缀和后缀,如果自定义属性探测器,那么此项配置不起作用 # prefix: ENC_( # suffix: ) # 自定义的属性探测器,如果这个是自定义的,那么上述的前缀后缀不生效 detector-bean: encryptablePropertyDetector # 自定义解密逻辑类 如果配置了,默认的解析器将不工作 resolver-bean: encryptablePropertyResolver # 过滤器的bean filter-bean: encryptablePropertyFilter # 过滤器配置,正则 filter: # 默认包含的 include-names: # 默认拦截的,默认拦截jasypt.encryptor的配置 exclude-names: - ^jasypt.encryptor.*
10. 使用mvn插件加密解密
使用代码的方式比较不方便,还需要编码实现,如果不想编码,简单的进行加密解密,就可以使用maven的插件,使用mvn命令进行加密解密
10.1 引入Jasypt的maven插件
<build> <plugins> <!-- Jasypt 的maven插件 --> <plugin> <groupId>com.github.ulisesbocchio</groupId> <artifactId>jasypt-maven-plugin</artifactId> <version>3.0.2</version> </plugin> </plugins> </build>
10.2 加密
使用jasypt-maven-plugin插件加密明文密码:(如果配置项是默认值,可以不指定)
mvn jasypt:encrypt-value -Djasypt.encryptor.password="jaspyt_password" -Djasypt.plugin.value="root" -Djasypt.encryptor.algorithm="PBEWITHHMACSHA512ANDAES_256"
复制代码
- jasypt.encryptor.password 是秘钥,尽量复杂!不能放在代码和配置文件里面!不能泄漏
- jasypt.plugin.value 是要加密的明文密码
- jasypt.encryptor.algorithm默认加密算法是PBEWITHHMACSHA512ANDAES_256,需要有JCE(Java Cryptography Extension)支持,如果不想安装JCE,可以使用PBEWithMD5AndDES算法。windows下的jdk自带
进入项目所在的目录,输入命令,成功加密
10.3 解密
使用jasypt-maven-plugin插件解密密文密码:(如果配置项是默认值,可以不指定)
mvn jasypt:decrypt-value -Djasypt.encryptor.password="jaspyt_password" -Djasypt.plugin.value="pqsp6kvVfBcKoEltxP9MilGGRo8EE506mDWAuTFIKePDXMeArta13bT6Hl8QqVlC" -Djasypt.encryptor.algorithm="PBEWITHHMACSHA512ANDAES_256"
复制代码
- jasypt.encryptor.password 是秘钥,尽量复杂!不能放在代码和配置文件里面!不能泄漏
- jasypt.plugin.value 是要加密的明文密码,有ENC()包裹或者不包裹都可以
- jasypt.encryptor.algorithm默认加密算法是PBEWITHHMACSHA512ANDAES_256,需要有JCE(Java Cryptography Extension)支持,如果不想安装JCE,可以使用PBEWithMD5AndDES算法。windows下的jdk自带
进入项目所在的目录,输入命令,成功加密
