Capture the Flag
A CTF (Capture the Flag) is an online game played among programmers and hackers. It's a race to find a set of "flags" that are hidden across computer systems and other data sources. In essence, it's the physical version of Capture the Flag for the more technically minded. It's a game of offense vs. defense, the hacker trying their best to penetrate the defense of the system, in an attempt to find the message that the organizer left behind.
Recently, I decided it would be fun to make my own CTF! I'm not running an event, nor am I timing you on how fast it takes for you to solve these challenges. I just wanted to publish a few problems on my personal site in case you (the reader) enjoy solving hard problems and want to test your knowledge of the web, cryptography, steganography, binary, and servers.
