OTP cannot be decrypted unless you discern the unique pad.
They lost me here, how did this get figured out?
- ShaneWilton 12y agoI also completed the badge challenge (Though a few hours after this team), and as far as I know, there was no hint as to which line of the cryptex was the OTP. We just knew, from the 'YQESMJDOJOTM' comment on the one page, that the cryptex was involved, so we tried every line as a key until we got something. 1o57 tends to design most of his puzzles around similar ideas, so you just start to get a feel for how he works after a while.
- tlrobinson 12y agoAre the ideas similar enough that some of the steps could be automated?
- bfish510 12y agoThe winning team did a writeup on the event and how one of the sections they used automation to solve. I think it was a Vigenère cipher.
- ShaneWilton 12y agoYes. I'm working on a pet project called F0UND that's meant to automate as much of the badge challenge as possible. There will still be a lot of human effort involved, but I think a lot of the information gathering and cross-referencing can be automated. Next year the black badge will be mine, whatever it takes.
