监控java层的加密算法一个ROM（目前不支持RSA)
基于https://github.com/icew4y/crypto_filter_aosp项目基础上增加了功能：
- 增加logcat日志。
- 支持同时对多个app进行监控。
注意 代码可能有bug,不保证稳定运行。
源码基于AOSP 8.1.0_r1上修改。
make systemimage
adb reboot bootloader
fastboot flash system system.img
fastboot reboot
把需要监控加密算法的app包名写入/data/local/tmp/monitor_package
adb shell "echo com.example.test > /data/local/tmp/monitor_package"
adb shell "echo com.hookme >> /data/local/tmp/monitor_package"
查看logcat日志：
adb logcat -s "fishso"
