Hello world.

My name is Raphael. I have a big passion for information security and security engineering. Below you'll find some projects of mine that I'd love for you to check out. If you have any thoughts, suggestions, or just want to chat about all things tech - don't be shy and reach out!

Personal projects

PushBits
ISC Go

Inspired by Pushover and Gotify, my intention with this experimental project is to build a push notification server that is minimalistic and secure. Since notifications are sent via Matrix.org, no additional clients need to be maintained. So far it features multiple users and application management.

sectxt
ISC Rust

The security.txt standard was proposed so researchers have a definite endpoint to notify about vulnerabilities on a website. With this tool I want to help track the coverage of the standard among major websites, and see who implements it correctly.

hackenv
ISC Go

When having to run binaries during a CTF, I feel the urge to run it inside a sandboxed environment, even when knowing the challenge was created in good faith. Previously, I used Podman as a beautiful Docker alternative. With this project, I aim to move towards using a virtual machine while keeping a similar level of comfort.

tbunread
ISC Rust

After using Neomutt together with Notmuch for quite a while, I switched back to Thunderbird for higher reliability. However, Thunderbird is not really scriptable, so I had to come up with a way to at least show me very basic status information for my email accounts.

java-decompiler
ISC Dockerfile

A good decompiler can save a lot of work. There are many Java decompilers freely available, each with their individual strength, but some are a bit difficult to install. I wrote this Docker image to make them better accessible in one place.

Theft Protection
ISC C++

As the first embedded device I built outside of curricular activity, this project cost me quite a bit of trial and error. The core of the device is an Arduino Nano-compatible board attached to an accelerometer, an NFC reader, and an alarm buzzer. Once armed via NFC, it makes loud noises if moved in any direction.

urlprobe
ISC Rust

I’m a big fan of the UNIX philosophy to build small tools that do one particular thing well. Although there were solutions for checking the availability of large lists of URLs, I wanted to give it a shot myself. This is how urlprobe was born.

airquality
ISC C++

For this project, I grabbed an ESP8266 together with a CO2 sensor and built a device that publishes the measurements via MQTT. As a result, I now have a pretty graph on my Grafana dashboard displaying the air quality in my room in real-time.

vim-textobj-names
MIT Vim script

Vim is an awesome text editor and with Neovim things have gotten even better. Still, I’m missing some features - one of which this project implements. This plugin makes editing variable and function names a lot easier.

dotfiles
Shell Vim script

I’ve been customizing my configuration files for many years and decided to publish them in a new repository. This project helps me tailoring my working environment to my needs and automating certain tasks on the command line. Among others, it contains configurations for Neovim and Zsh.
