 1 | ## 通付盾第一代安全加固方案开源
 2 | ---
 3 | #### 项目简介
 4 | APK安全加固是面向移动应用程序的深度安全保护服务，可以为您的APP穿上一层“软猬铠甲”，通过加密、加壳、RPC、动态加载等技术为您的应用进行全方位安全保护，有效防止逆向工程、反编译、嵌入病毒、非法扣费等恶意行为。
 5 | 
 6 | 随着Android ART模式和Android 5.0系统的普及，应用加固已全面迎来第二代API定制加固时代，需要更多的开发者和研究人员一起投入到移动安全行业。为了为移动安全领域做出更大的贡献，通付盾现开源第一代安全加固方案（Dex文件整体加密），树立移动安全开放精神和开源标准。加密等级和方案优劣上与友商的企业版相当，研究人员可在此基础上进一步优化。
 7 | 
 8 | 欢迎广大移动安全研究人员积极投入其中，一起投入安全加固技术的研究。第一代安全加固产品内容主要包含：
 9 | 
10 | - Dex文件保护
11 | - 资源文件保护
12 | - xml文件保护
13 | - 内存保护
14 | - so保护 
15 | 
16 | 与此同时，通付盾已全面推出第二代API定制加固产品，完美兼容Android ART和Android 5.0，并独家通过监管部门的安全加固保护效果检测。
17 | 
18 | 欢迎使用！
19 | 
20 | #### 项目构成
21 | 该项目的开源分组件进行，将第一代安全加固中使用的关键技术改造成可独立使用的安全组件，方便广大开发者对其用途进行扩展。主要的部分有：
22 | 
23 | - RawDexClassLoader ：自定义封装的DexClassLoader，可以实现将一段内存中Dex文件的映射加载进虚拟机。
24 | -  其余组件待发布
25 |

 1 | ## RawDexClassLoader简介
 2 | ---
 3 | #### 简介
 4 | RawDexClassLoader是自定义封装的ClassLoader，使用方式与DexClassLoader基本类似，不过可以将内存中Dex文件的映射加载进虚拟机，目前支持Android2.2到Android4.4的Dalvik模式。
 5 | 
 6 | #### 结构
 7 | - src目录，为Java层源代码。其中`DemoActivity.java`为测试用例，与assets下的dex文件配合使用。
 8 | - jni目录，为Native本地代码，用于编译动态链接库，源代码后续会放出（目前还没增加兼容ART的部分）。
 9 | - assets目录，为测试用的dex文件。代码如下：
10 | 
11 | ```Java
12 | public class TestClassLoader {
13 |     private static int a;
14 |     
15 |     public TestClassLoader() {
16 |         // TODO Auto-generated constructor stub
17 |     }
18 |     
19 |     public static void setValue(int value){
20 |         a = value;
21 |     } 
22 |     
23 |     public static int getValue(){
24 |         return a;
25 |     }
26 | }
27 | ```
28 | 
29 | - libs目录，为需要链接的动态链接库。
30 | 
31 | #### 使用
32 | 本项目为Android工程，git clone到本地之后直接导入IDE，作为Android应用运行，如果执行成功的话会在Activity中弹出相应的Toast。
33 | 如果需要将源码集成到自己的工程中，可以将动态链接库放到自己工程的libs目录下，将除`DemoActivity.java`中的代码拷贝至自己的工程中，当然除此之外还可以将此工程导出成Jar包进行使用。
34 | 
35 | #### 更新
36 | 2015-1-21：
37 | - 创建项目，更新Java层代码和动态链接库。
38 |
