If I ever considered a transition into cryptography, this story just blew that idea up for me, forever.<p>I can&#x27;t imagine trying to solve this! You&#x27;d have to love puzzles with an insatiable appetite to endure this.<p>Good job, team.

This kind of thing would make DefCon challenging for me, I&#x27;d get into the puzzles and not attend any of the talks as I tried to figure them out!

Taking the following line from the Cryptex we can decode our message.<p>BBVB4RCVARLU<p>This is whats called an OTP or One Time Pad encryption. <a href="http://rumkin.com/tools/cipher/otp.php" rel="nofollow">http:&#x2F;&#x2F;rumkin.com&#x2F;tools&#x2F;cipher&#x2F;otp.php</a><p>OTP cannot be decrypted unless you discern the unique pad.<p>They lost me here, how did this get figured out?

Loved reading this. Some incredible reasoning, even being shown the answer there are multiple stages I can&#x27;t follow the reasoning that allowed them to progress. Kudos, respect, and jealousy!

Great Walkthrough. How long did it take to get through the challenge?

I love the use of Google&#x27;s Latin-English dictionary. Which amazingly also includes the word microwave.

That was kinda insane! Now I have to wonder just how many bits of random stuff get handed out to Defcon attendees that might or might not be part of some sort of puzzle like this.

I can&#x27;t believe someone solved this. Champion effort.

This made my head spin. Fun ride! I&#x27;m always in awe of crypto guys. Truly, their mind works in a different way!

I loved this article.<p>Unfortunately I now have a burning urge to rejoin TBW ARG which I thought I had escaped from :(
