      Hello! Just a bit confused about this case file. Does it affect the cipher for challenge 3B or for a different challenge?

      Fair enough. The case files 3.1 and 3.2 are to help you with Challenge 3B. Sorry if that was not clear.

        Obviously you can’t give too much away but do you have any tips on how to solve this? I have an idea on what cipher it is based off the frequency but am not sure about how to determine the key length. Once again I understand if you aren’t allowed to help, but I don’t quite understand how to analyse when frequency analysis doesn’t work. Is there anything you can do with n-grams? Any help would be much appreciated.

        These are excellent questions. Any hints we give will be in the Case Files, and we will update them over the next week, so keep an eye on that page. Good luck!
