Cute Floating Ghost

July 2023 | Shader, GLSL, Ray marching
This animation was created using ray marching and shader math. I draw the ghost that floats and moves in the ocean!
There will be a blog post about this! Stay tuned!

Ascii art web server

April 2023 - May 2023 | Server, Concurrency, OS
This project created a server with a web interface that takes a URL to an image and converts it to ASCII art. The server spawns worker threads and spreads the incoming connections to the different workers to allow concurrent processing. The server experiments with the new proc_fd and the ability to pass file descriptors to a different process.

Padding Oracle On Custom Padding Methods

March 2023 - April 2023 | Cryptography, Block Cipher
Discovered efficient attack method against novel padding method proposed in this conference paper
Created a CTF challenge based on the attack method in HITCON CTF

Vulnerability Explorer

January 2023 - present | Python, Flask, Compiler | !Note that this project is still in the idea phase
Visualized execution of vulnerable program graphically for better comprehension
Implemented a simplified compiler for easy experimentation

mktmpdir

January 2023 | Shellscript, Bash
This is a simple shell script that drops the user into a temporary folder. This script allows users to do simple experiments without worrying about messing up the folder structure. The script supports keeping the result of the temporary folder and naming the session

Raspberry PI Remote Display Server

December 2021 | Python, Flask, LCD display
Designed Interaction between web server and hardware LCD screen
Allowed easy management of remote display with real-time monitoring
Implemented a simple database for swapping previously displayed images

Ferris Sweep Keyboard

December 2021 | Micro-controller, Keyboard, Soldering
I attempted to create my own keyboard using the ferris sweep 34 key design. I used nice-nano microcontroller along with the zmk firmware to support Bluetooth connection. The link above goes to the zmk config I used during the build.
