I was talking to a friend recently when I realized that the challenges I designed for the Pittsburgh Hacker’s Association’s first four meetings (prior to my return to Texas) were no longer readily available. If anyone still wants to play through them I’ve decided to just share them here. Enjoy!

PHA 0x01
A mixture of substitution ciphers is where this starts. Get it here.

Fill-a-what now? A normal Fillomino puzzle, which was going to give the key material for PHA 0x04 which didn’t happen. 😦 Get it here.
