Signal Captcha Helper

Signal's captcha system is designed to be used in an embedded browser. This utility provides that and the bare minimum to parse the resulting token.

pre-compiled binary

no need to install valac

• linux amd64
• linux arm64

build

if you can't or don't want to use the pre-compiled binaries

valac --pkg gtk+-3.0 --pkg webkit2gtk-4.0 signal-captcha-helper.vala

use

The captcha token is output to standard out when the program completes, so you probably want to launch this tool from the terminal so you can see the output. There are no options (for now), so just invoke it directly.

For a captcha token to use when registering an account:

./signal-captcha-helper

for a challenge token to use to send messages:

./signal-captcha-helper --challenge
