Hi, I'm Cauã. I mostly build Telegram bots and small tools to automate things in my day-to-day.
I've also sent some PRs to open source projects I use:
- Lightpanda, a headless browser written in Zig. I implemented several
crypto.subtlealgorithms: RSA-OAEP, RSA-PSS, RSASSA-PKCS1-v1_5, ECDSA, Ed25519, X25519 and AES-KW. (PRs) - AnyPS5, which ports PS5 executables to Windows and Linux. I fixed
sceHttpParseResponseHeaderto match what a real PS5 does, and some build tools that broke on non-ASCII paths on Windows. (PRs) - obscura, another headless browser, written in Rust. I added AES-KW key wrapping. (PR)
Some of my own projects:
- SVGtoTGS: converts an SVG into a Telegram custom emoji (
.tgs), tuned to stay legible at the size emoji actually show up in chat. - BlaBlaCarFind: a Telegram bot that lets you know when a new ride is posted on a BlaBlaCar route.
