app协议逆向破解

思路：这种app逆向方式比较通用，能够解决大部分app协议加密破解。主要思路是利用frida hook java jdk 中的加密
函数与方法，打印响应参数分析

逆向步骤

  1. 启动脚步js_hook.js (frida -U -l js_hook.js -f com.lang.testso --no-pause)

    • 脚步中包含了hook MD5 AES DES RSA 等一些列加密算法；以及解决app 无法抓包的ssl ping脚步

  2. 启动app点击发送请求，查看响应日志

    • AES AES
    • RSA RSA

  3. 还原算法，测试代码在com.lang.script下，将打印的16进制转换为byte字节数组，还原加密现场
