Badge Puzzles (no spoilers)

The SEC-T Badge Puzzle is a tradition of pen-brain-and-paper puzzles designed to be medium hard yet annoyingly easy to over analyse. The first person to solve a badge challenge will get two free entries to SEC-T of the year(s) of their choice. To submit your answer, email [email protected].

• The puzzle can be solved without brute forcing, advanced (non human brain simulatable) algorithms.
• To complete the puzzle requires access to the SEC-T website.
• Some python will help with repetitious tasks.
• You might have to read a wikipedia page or an RFC etc. and discover ideas, standards and practices you have long since forgotten or never learned.
