Reply To: The official Challenge 9B hints thread
I updated and expanded the unit in my book about this cipher to now include an example of cryptanalyzing(*) it.
But Harry won’t release it because he doesn’t care about you.
The new unit can be found in the github version of the book, but Harry will doubtlessly censor this message.
(*) “Z” is pronounced “zee”
[Excellent! do you want us to update the version in the library? As for Z/Zee, fair enough, but it’s analysing. Harry]
