(五)配置文件的属性加密

在micro service体系中,有了config server,我们可以把配置存放在git、svn、数据库等,普通的web项目也基本上是把配置存放在配置文件中。如果我们把大量的配置信息都放在配置文件中是会有安全隐患的,那么如何消除这个隐患呢?最直接的方式就是把配置信息中的一些敏感信息(比如数据库密码、中间件密码)加密,然后程序在获取这些配置的时候解密,就可以达到目的。这个时候,jasypt框架就派上用场了。

Jasypt is a java library which allows the developer to add basic encryption capabilities to his/her projects with minimum effort, and without the need of having deep knowledge on how cryptography works.

  • High-security, standards-based encryption techniques, both for unidirectional and bidirectional encryption. Encrypt passwords, texts, numbers, binaries...
  • Transparent integration with Hibernate.
  • Suitable for integration into Spring-based applications and also transparently integrable with Spring Security.
  • Integrated capabilities for encrypting the configuration of applications (i.e. datasources).
  • Specific features for high-performance encryption in multi-processor/multi-core systems.
  • Open API for use with any JCE provider.
  • ...and much more

意思其实就是可以把Jasypt这个Java库当成是一个黑盒子,无需深入了解里面怎么运作的,可以拿来直接用(当然,作为码农我们还是要去一探究竟的,个人兴趣自己看吧)。现在基本上项目都集成spring boot了,因此我们可以使用jasypt-spring-boot-starter

1. 引入pom包

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

2. 找到maven仓库中的 jasypt-1.9.2.jar(路径是:.m2 epositoryorgjasyptjasypt1.9.2

3. 调用jasypt-1.9.2.jar包中一个main方法org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI ,源码参考:

package org.jasypt.intf.cli;

import java.util.Properties;
import org.jasypt.intf.service.JasyptStatelessService;

public final class JasyptPBEStringEncryptionCLI
{
  private static final String[][] VALID_REQUIRED_ARGUMENTS = { { "input" }, { "password" } };
  private static final String[][] VALID_OPTIONAL_ARGUMENTS = { { "verbose" }, { "algorithm" }, { "keyObtentionIterations" }, { "saltGeneratorClassName" }, { "providerName" }, { "providerClassName" }, { "stringOutputType" } };
  
  public static void main(String[] args)
  {
    boolean verbose = CLIUtils.getVerbosity(args);
    try
    {
      String applicationName = null;
      String[] arguments = null;
      if ((args[0] == null) || (args[0].indexOf("=") != -1))
      {
        applicationName = JasyptPBEStringEncryptionCLI.class.getName();
        arguments = args;
      }
      else
      {
        applicationName = args[0];
        arguments = new String[args.length - 1];
        System.arraycopy(args, 1, arguments, 0, args.length - 1);
      }
      Properties argumentValues = CLIUtils.getArgumentValues(applicationName, arguments, VALID_REQUIRED_ARGUMENTS, VALID_OPTIONAL_ARGUMENTS);
      
      CLIUtils.showEnvironment(verbose);
      
      JasyptStatelessService service = new JasyptStatelessService();
      
      String input = argumentValues.getProperty("input");
      
      CLIUtils.showArgumentDescription(argumentValues, verbose);
      
      String result = service.encrypt(input, argumentValues.getProperty("password"), null, null, argumentValues.getProperty("algorithm"), null, null, argumentValues.getProperty("keyObtentionIterations"), null, null, argumentValues.getProperty("saltGeneratorClassName"), null, null, argumentValues.getProperty("providerName"), null, null, argumentValues.getProperty("providerClassName"), null, null, argumentValues.getProperty("stringOutputType"), null, null);
      
      CLIUtils.showOutput(result, verbose);
    }
    catch (Throwable t)
    {
      CLIUtils.showError(t, verbose);
    }
  }
}
View Code

然后执行一下语句:

java -cp jasypt-1.9.2.jar  org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input="test" password=salt algorithm=PBEWithMD5AndDES

-- input参数:你想要加密的密码
-- password参数:jasypt用来加密你的密码的密码

结果如下图,途中的output就是加密后的密文了。

4. 修改配置文件,把配置文件中要加密的字段改为:ENC(密文)

system:
  mysql:
    url: xxx.xxx.xx.xx
    username: username
    password: ENC(qh8kixDUkvm1DIJrpLFtzw==)

jasypt:
  encryptor:
    password: salt

以上就可以达到目的。
