Welcome

This tag is used for introductory challenges aimed at CTF beginners. It is recommended as a first challenge.

*A "tag" is a label that represents a challenge's characteristics or solution approach. Looking at the tags helps you understand what kind of theme a challenge has. By choosing tags that interest you, you can more easily find challenges that suit you or related challenges. Be careful, because tags can sometimes spoil the solution. On the other hand, you can also use them as hints when you get stuck.
