<!-- ABOUT THE PROJECT -->

About The Project

This is a repository to store CTF challenges to be deployed for csictf.

<!-- GETTING STARTED -->

Getting Started

> Note: This is a beginner CTF, hence the challenges should be of easy / moderate difficulty.
<br />

> Note: DO NOT PLAGIARIZE challenges from other CTFs. You can take inspiration but not have the exact same challenge.

The following are the categories of challenges that are to be made:

Installation

1. Clone the repo

Template

Flag Format

Here's a regex for the flag format.

Here's a sample flag.

Directory Structure

The following are guidelines for creating challenge folders.

> The static folder contains images that may be used in the README.md.

Template for Challenge README

As mentioned earlier, each challenge requires a README. The README must be written in such a way that this can serve as an official write-up later. This should have the following format.

' -->
\

Exploit

<!-- Much more detailed description than the following. -->
Reverse sample.py to decrypt the flag in sample.txt.
<br />

The last line should be the flag.
<br />

The flag is:

\
``

> Refer to this sample for writing the exploit section.

challenge.yml

Every challenge must have a challenge.yml, in the format specified in challenge-example.yml. This is MANDATORY, without this the challenge will not be deployed. Remove the comments in the specified format, leave out the value, decay and minimum keys as they are in the template. Every challenge has 500 points initially and decays to 100 points over 450 solves.

Dockerfiles

Here are some Dockerfiles you can refer to while making your own. Make sure you test it locally before making the PR.

Make sure you read the Dockerfiles and include the necessary files like the flag.txt. REMEMBER TO ADD THE README.md and challenge.yml FILES TO .dockerignore, BECAUSE IT HAS THE SOLUTION..

<!-- CONTRIBUTING -->


Contributing

Besides contribution of challenges, contribution of *ideas* for challenges is also appreciated. You can put forward your ideas to , and .
<br />

Contributions are what make the open source community such an amazing place to be learn, inspire, and create. Any contributions you make are greatly appreciated.

1. Fork the Project.
2. Submit your idea for the challenge in the respective README.
3. File a Pull Request with the challenge-idea tag. Each challenge must have it's own PR.
4. Once the challenge is approved, the tag is changed to challenge-approved, we comment on the PR.
5. Build the final challenge and update the *same* PR.
6. Make sure all commit messages are in accordance with the guidelines in CONTRIBUTING.md.
7. Any issues in the challenge will be addressed using GitHub Issues.

You are requested to follow the contribution guidelines specified in CONTRIBUTING.md while contributing to the project :smile:.
