Projects_
CTFOJ
An open-source online judge specifically designed for hosting interactive cybersecurity challenges and contests. Features include practice problems, contests, an admin console, two-factor authentication, a comprehensive test suite, and live rankings. Built with Flask, in collaboration with jdabtieu.
submission-downloader
A customisable tool used for archiving code submissions in bulk from a wide variety of programming sites. Packaged with the pip package manager, and can easily be modified to archive code from unsupported sites. Especially helpful for creating solution archives.
stonktrack
A financial tracker that can track stocks, cryptocurrencies, forexes, and more with simple configuration files and a terminal-based gui. It's built with Python and urwid, and it's superior to other terminal stock trackers because of the real-time data, variety of assets, and unlimited free updates. Comes with coloured and scrollable versions.
snakewhisper
A simple end-to-end encrypted chat program written in Python. It's functional (it currently supports two-way communication with elliptic curve key exchange and AES-128 encryption), but snakewhisper is primarily a proof-of-concept that showcases how regular computer users can easily access—or even create—chat programs with end-to-end encryption.
chenanthony.com
A website that hosts a short description of myself, my resume, a listing of my projects with a short description for each one, my contact information, and my blog. Eventually, web applications and PHP applications that I create will also be accessible here. Accessible online at chenanthony.com.
simple-markov
A fast and simple Markov chain-based text generator written in C++. The number of preceding states used, temperature of the generated text (how "random" it looks), and number of words to generate are all configurable. Can be used to generate words letter-by-letter, sentences word-by-word, and [indirectly] paragraphs sentence-by_sentence.
RC4-drop
An object-oriented implemention of RC4-drop[n], a modification of the simple and speedy RC4 stream cipher that defends against the Fluhrer, Mantin and Shamir attack by discarding the first n bytes of the keystream after key generation. Can also be used as regular RC4 by setting n = 0, or a performant pseudorandom number generator.
GenNet
A novel way to connect with the generations of your family before and after you, GenNet allows users to create "trees" for their families and populate the "leaves" of the tree with pieces of knowledge, anecdotes, or photos and videos. Built in collaboration with AbdulBaseetShabi, Arihan10, and divyxnsh at Hack the North 2021.
simple-markov
A fast and simple Markov chain-based text generator written in C++. The number of preceding states used, temperature of the generated text (how "random" it looks), and number of words to generate are all configurable. Can be used to generate words letter-by-letter, sentences word-by-word, and [indirectly] paragraphs sentence-by_sentence.

zoetrope-game-of-life
A high-speed console-based Python implementation of the famous cellular automaton. It appears to move despite being non-animated, much like a Zoetrope. Turing-complete, it can theoretically simulate any computer algorithm in existence. The picture shows a Gosper glider gun in action.
divoc: covid tracker
A COVID-19 tracker that uses several public APIs to generate a count of the number of COVID-19 cases within a certain customisable distance of any address in Ontario. Includes a COVID-19 self-assessment tool that takes the number of cases near you into account. Created during TOHacks 2020 in collaboration with Maillew and tankibuds.

A customisable tool used for archiving code submissions in bulk from a wide variety of programming sites. Packaged with the pip package manager, and can easily be modified to archive code from unsupported sites. Especially helpful for creating solution archives.
mersenne-twister-tools
A collection of various programs that implement or relate to the popular Mersenne Twister PRNG in some way. Intended to be a simple implementation that users can build off of. Includes the original 32 and 64-bit versions, other popular variants, programs to crack the state of the Mersenne Twister, and programs to time travel and reverse the Mersenne Twister.
exactum
A flexible web monitoring tool for websites that have no built-in update notification system. Configured with YAML, Exactum supports multi-platform desktop notifications, email notifications, and logging changes to a file. Created during Hack the North 2020 in collaboration with AlanL2 and Maillew. Project website available here.

ai-tictactoe
An object-oriented tic-tac-toe using artifical intelligence. Available with both CLI and GUI clients (built with pygame), ai-tictactoe uses the minimax algorithm with alpha-beta pruning to play the optimal move every time. Finally, this program can be modified to play other games like Gomuku and Connect Four.
simple-markov-flask
A Flask frontend for the simple-markov script, it seamlessly integrates an HTML/JS/CSS frontend with the original C++ program serving as the backend. It also uses hCAPTCHA to prevent Denial of Service attacks while still respecting users' privacy. It's hosted on this site here, and users can upload custom text training data to test it.
cryptopals-solutions
A repository of my solutions to the cryptopals cryptography challenges. Common advice is to "never roll your own". However, this advice should be amended to "never use your own". With the rise in digital threats, any computer programmer should at least have a basic understanding of cryptography. And what better way to learn than by doing?
