StringFog

本项目基于开源项目 StringFog 进行openharmony 的移植和开发,可以通过项目标签以及github地址( https://github.com/MegatronKing/StringFog )追踪到原安卓项目版本**

项目介绍

  • 项目名称:StringFog
  • 所属系列:openharmony 第三方组件适配移植
  • 功能:一款自动对dex/aar/jar文件中的字符串进行加密的插件工具
  • 基线版本:StringFog release v1.1.0
  • 项目移植状态:主功能完成
  • 调用差异:无
  • 开发版本:sdk5,DevEco Studio2.1 beta3
  • 项目作者和维护人:邢碌
  • 联系方式:xxx@chinasoftinc.com

效果演示


  • 加密前:
String a = "This is a string!";
  • 加密后:
String a = StringFog.decrypt("ABCDEFGHIJKLMN");
  • 运行时:
decrypt: "ABCDEFGHIJKLMN" => "This is a string!"

安装教程

在moudle级别下的build.gradle文件中添加依赖

// 添加maven仓库
repositories {
   maven {
       url 'https://s01.oss.sonatype.org/content/repositories/snapshots/'
   }
}

// 添加依赖库
dependencies {
   implementation 'com.gitee.chinasoft_ohos:stringfog:0.0.1-SNAPSHOT'   
}

在sdk5,DevEco Studio2.1 beta3下项目可直接运行 如无法运行,删除项目.gradle,.idea,build,gradle,build.gradle文件, 并依据自己的版本创建新项目,将新项目的对应文件复制到根目录下

使用

由于开发了gradle插件,所以在集成时非常简单,不会影响到打包的配置。插件已经上传到jcenter,直接引用依赖就可以。

1、在根目录build.gradle中引入插件依赖。
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        ...
        classpath 'com.github.megatronking.stringfog:gradle-plugin:2.2.1'
        // 选用加解密算法库,默认实现了xor和aes-cbc两种简单算法,也可以使用自己的加解密库。
        classpath 'com.github.megatronking.stringfog_ext_xor:xor:1.1.0'
    }
}
2、在moudle或lib的build.gradle中配置插件。
apply plugin: 'stringfog'

stringfog {
    // 这是加解密key,可以自由定义。
    key 'Hello World'
    // 开关
    enable true
    // 加解密库的实现类路径,需和上面配置的加解密算法库一致。
    implementation 'com.github.megatronking.stringfog_ext_xor.StringFogImpl'
    // 指定需加密的代码包路径,可配置多个,未指定将默认全部加密。
    fogPackages = ['com.xxx.xxx']
}
3、在moudle或lib的build.gradle中引入加解密库依赖。
dependencies {
      ...
      // 这里要和上面选用的加解密算法库一致,用于运行时解密。
      compile 'com.github.megatronking.stringfog:xor:1.1.0'
}

扩展

注解反加密

如果开发者有不需要自动加密的类,可以使用注解StringFogIgnore来忽略:

@StringFogIgnore
public class Test {
    ...
}

自定义加解密算法实现

实现IStringFog接口,参考stringfog-ext目录下面的两种算法实现。注意某些算法在不同平台上会有差异,可能出现在运行时无法正确解密的问题。如何集成请参考下方范例!

public final class StringFogImpl implements IStringFog {

    @Override
    public String encrypt(String data, String key) {
        // 自定义加密
    }

    @Override
    public String decrypt(String data, String key) {
        // 自定义解密
    }

    @Override
    public boolean overflow(String data, String key) {
        // 最大字符串长度为65536,这里要校验加密后是否出现长度溢出,如果溢出将不进行加密。
        // 这里可以控制符合某些条件的字符串不加密。
    }

}

Mapping文件

加解密的字符串明文和暗文会自动生成mapping映射文件,位于outputs/mapping/stringfog.txt。
