TLS

JA3

ClientHelloSpec does not store the TLS Version for the initial Client Hello, only SupportedVersionsExtension:

https://github.com/refraction-networking/utls/blob/0b2885c8/u_common.go#L114-L117

Then, for the initial Client Hello, TLS version 1.0 is used:

https://github.com/refraction-networking/utls/blob/0b2885c8/conn.go#L944-L948

To solve, we need to make our own struct. Here are some examples:

pcap

First install:

https://github.com/emanuele-f/PCAPdroid

Start app, then change from HTTP Server to PCAP File. Then click start, if prompted to save, choose Downloads. Start Google Chrome and wait for a page to load. Then stop monitoring, and copy file to computer:

adb ls /sdcard/Download
adb pull /sdcard/Download/PCAPdroid_22_Oct_15_19_28.pcap
