前提條件

一臺root手機
frida環(huán)境一套
還要會搜索（回復(fù)比較慢）

開啟抓包

1.手機中執(zhí)行tcpdmp

tcpdump -i any -s 0 -w /sdcord/Download/capture.pcap

2.手機沒有tcpdump的可以下載

https://www.androidtcpdump.com/android-tcpdump/downloads

adb push tcpdump /data/local/tmp/ (如果遇到權(quán)限不夠的，先push到sdcard/ 再移動過去)

2.1在手機中執(zhí)行賦予權(quán)限

chomd 777 tcpdump

2.2繼續(xù)執(zhí)行操作

./tcpdump -i any -s 0 -w /sdcard/Download/capture.pcap

hook app 拿到sslkey

frida -U -f package -l ./sslkeyfilelog.js --no-pause

將抓包文件拿到pc

• 將/sdcard/Download/capture.pcap pull 到pc

保存frida輸出的打印信息到sslkey.txt（還沒做到一鍵傻瓜化）

//格式是這樣的，不要參雜別的
