My name is Arthur, better known under the nickname Vozec and I am passionate about computer science, more precisely about cybersecurity. I learn new things in autodidacts in parallel to my post-baccalaureate studies and this GitHub contains many projects that I did by myself. I participate to many CTF and many of the new tools I create allow me to save time during these competitions.

I also have a web site: vozec.fr on which I publish articles ranging from global cybersecurity topics to more specific ones in cryptography.
