Welcome to the (formerly*) Longest Two-Day CTF

Once upon a time, The Long Con had an extra hour for challenge decoding and discovery. The clocks no longer change, but there's still plenty of time to lose yourself in a few puzzles.

Running alongside The Long Con conference, this beginner-friendly CTF offers a collection of challenges to test your curiosity.

* Manitoba discontinued seasonal clock changes, robbing us of our extra hour and perfectly good naming gimmick. We're still bitter.
