WiCyS 2024 Crypto CTF Challenge Repo

Put your challenge in chals/[category]/chalname

Flag format is sigpwny{}

Each challenge should have a challenge.yml so we can put on CTFd. Use chals/crypto/add_one/challenge.yml as a template.

If your chal needs to be deployed, create your Dockerfile (look to pwn chals for reference, or look to internal CTF repo for reference for your chal type) and add an entry to the docker-compose.yml file.

CI

As soon as you push to main, your challenge will be automatically added to ctfd according to your challenge.yml, and your chal will be auto deployed if it is writtein in docker-compose.yml.

Lazy Development

Make sure your Dockerfile builds.

docker build .

Then make sure your challenge works.

docker run -p 0.0.0.0:1337:1337/tcp --rm -it $(docker build -q .)
