1 | # Java内存马分析辅助工具
2 |
3 | 目的是快速完成重复性的工作，内存马编写测试分析总离不开下面三部分的互相转换
4 |
5 | java源码 <--> class字节码 <--> base64编码
6 |
7 | 其中java编译为class需要对应环境依赖，工具不考虑做，剩下的就是class字节码和base64互转，以及base64直接查看java源码。
8 |
9 | 通过base64保存class文件和直接查看java源码的功能。
10 |
11 | ### 使用方法
12 |
13 | ```bash
14 | java -jar GuiTool-1.0.jar
15 | ```
16 |
17 | ### 待办
18 | - [x] base64保存class文件
19 | - [x] base64直接查看java源码
20 | - [ ] 上传class转化为base64
21 | - [ ] ...
22 |
