+I'm Valentin, an computer science student from Regensburg, Germany. Currently I'm studying at [OTH Regensburg][1].
 
 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 wargames.
 
 I'm coding since ~2010.

-This website is generated by the static website generator [Hugo][1] using the awesome [After Dark theme][2]. I track the source files of the website in a [GitHub repository][3]. Everything is written using the [Vim][4] text editor. The web server is a [nginx server][5] running on my own dedicated server from [Kimsufi][6] and does not log the visitors IP address (I **do** write access logs but I will never log IP addresses).

 I chose a static site generator over a CMS like WordPress because plain markdown files are easier to manage e.g. using git in contrast to WordPress posts being stored somewhere deep in a database. Also have a look at the [WordPress release notes][7]. Hugo generates static HTML files which are served through nginx, so there are no security risks.
 
 The web server forces you to use a TLS encrypted connection using HTTP/2, therefore I used [Let's Encrypt][8] to get a free certificate (you might want to check out my awesome [SSL rating][9]).
