Badge Challenge Build Part 8


This one is all about the onetime pad and youtube videos.

If you followed along with part 6 you will have a PDF with some hex, and a collection of hex from badges.

This is the hex from one of the PDF's:

7C4E44C83D6610F8C517AC24D755AFA4AA6ADA1FD03C6E1BEC2843B3D634

NOTE: you only get to see one of the two PDF's depending on which team you are on.


If you don't know what a onetime pad is then google might help, and wikipedia has a good article about Onetime Pad's


So all we need to do is XOR that hex with some other hex.

The badages have hex, and by now you should have sorted then into a simgle block of hex.


The hex from the badge:

143A30B84E5C3FD7BC78D950A27BCDC18528B1799D79082AD41C0883D634



And then we do the XOR:

7C4E44C83D6610F8C517AC24D755AFA4AA6ADA1FD03C6E1BEC2843B3D634

143A30B84E5C3FD7BC78D950A27BCDC18528B1799D79082AD41C0883D634

If we convert the hex to ascii, we get a youtube link:
