Template

Flag format

• All flags are enclosed in CCC{}.
• All flags passes the regex CCC{[a-zA-Z0-9_!@#$%^&*()-=+?]+}.
• Flags are hard to guess (I believe so) :D

Directory structure

• Each challenge is in its own directory
• Each challenge directory contains a README.md file with the challenge description and solution
• Every challenge that requires a server to be run is in its own docker container, so they have their own Dockerfile in challenge directory
• src directory contains all the source code for the challenges
• files directory contains all the files that are needed for the challenges

Template for Readme.md

Every README.md file follows the following template:

# Challenge Name
Category: Category Name
