Useful CTF Commands: Gobuster
While helping new CTF (Capture the Flag) players with their first challenges, I noticed that it would be helpful to have an overview of commonly used commands and tools.

But perhaps that is not the main goal of the libary, it delivers much more features like the generation of certificates itself or the generation of signing requests as example. Perhaps the best description of the functions would by everything what has to do with native SSL/TLS certificate actions is included.
