Hey there!

It's me! Paul. You may also know me as @vanitasvitae.

I'm a free software enthusiast and computer science student from Germany, Planet Earth.

My main interests are free and open protocols such as XMPP and OpenPGP.
If you want to read more, feel free to check out my blog.

I'm the developer of PGPainless, an OpenPGP-focussed wrapper around BouncyCastle.
The goal of this project is to improve the OpenPGP tooling for Android and Java-based systems.

In my spare time I'm working on improving the XMPP ecosystem by working on protocol extensions related to end-to-end encryption, or by contributing to the XMPP client library Smack.

Since I'm a passionate coffee drinker, you can support me by providing me with coffee ☕ ❤️
