You are on the website of Carl Munk. I have a master of informatics and I work as a free developer for different companies. On my website I’m posting knowledge, tips and news from the branch. Cryptography, internet security and unblocking are also topics that are very interesting for a lot of people. I’m often asked how this works, so I try to write the articles even understandable for non-techies. If you have questions please post them in the comments, as I don’t have much time to answer private e-mails.
