Your progress

Run ctf export in Termux, copy what it prints, and paste it below. This page reads it and shows you the whole picture: what you have captured, what is left, and how many points you have.

What this page can and cannot do It cannot check your answers. Every flag comes from a seed that only exists on your device, so this site has no way to know whether a capture is real, and it will not pretend otherwise. What you paste is stored in your browser, is never sent anywhere, and is a record of what the tool told you. The tool is where the score is real.

Paste your export

In Termux:

ctf export

Then paste the JSON below. It starts with { and ends with }.

How the numbers are worked out

The export carries one entry per challenge with whether it is captured and how many hints you asked for. 6 challenges, 120 points, and the same tool version this site was built against.

Because the file names and the flags differ per device, the export also carries a short one-way device name. Two exports from the same phone carry the same value, which is what makes it useful as a label, and it reveals nothing about the seed.
