Under The CTF


I recently put Under The CTF online. It's a collection of software puzzles that I've written over the last few years.

These 20 challenges form a Capture The Flag (CTF) competition. They range in difficulty from beginner to advanced, and include web, cryptography, and Python puzzles.

I added it to my projects page. The source code is on GitHub.
