About me

About me
OK, I think the main topic of this blog should be really clear, isn't it?  It includes everything regarding security, vulnerabilities, wargames, cryptography and a little bit of coding. However, here you will find some information about me, my (research) activities and hopefully some general useful information :-)
All right, I hope you enjoy your visit and of course if you have any questions, please do not hesitate to contact me :-)
