 This challenge in Ryan Nicholson CTF is called Encoded Credentials. It's only worth 10 points in the beginner section. And the prompt here is, what's the password sent following this get request? And they give us this get request in monospace code characters here. So in this HTTP headers, you can actually see everything that's going forth in the communication in the HTTP protocol. When you try and access a website that actually asks you for a username and password, like Natus is a good example. They actually keep note of that in a basic authorization like header tag. So it's just simply the syntax authorization equals basic, and then this information that is base 64 encoded. So you haven't seen base 64 before, you can check it out on Wikipedia, but it is simply an encoding or representation of actual sum data, but it compresses it all into letters and numbers and occasional equal signs and pluses and forward slashes. So it's pretty handy, but it's only just an encoding scheme. So if we wanted to, we could echo this into base 64 tag D to decode, and we immediately get, okay, the username is admin and the password was a Unicornic. So we can cut this up again using a colon as our limiter. Check out the second field and we'll take note of this as our, okay, cool, that did actually include all of it, as our get flag script. So if we wanted to nano get flag.sh, just include our Shebang line and simply we have this marked as executable and we can run this as our get flag script. That is the flag we would submit and we can mark this challenge as complete. So very, very simple, very, very easy, but good to know for a CTF notion.
