About Me

I’m Valentin, a computer science student from Regensburg, Germany. I received my bachelor’s degree after graduating from OTH Regensburg in 2018 and am currently attending Ruhr Universit├Ąt Bochum for my master’s degree.

My interests are mainly in IT security and open source software but also practical cryptography and blockchain based technologies. I also like administrating Linux machines and planing network infrastructures. In my free time I like to play around with binary analysis and exploiting techniques by solving CTFs and wargames.

I’m coding since ~2010.

Currently working at EBSnet.

The website, keyserver and mirrors are also available via Tor onion services.
