Reply To: The official Challenge 10 tips and hints thread
Thanks for the hints!
I had guessed that it was one of the so-and-so square ciphers, such as Playfair and its relatives, so it’s nice to be correct there. But from my searches I couldn’t find a guide on cracking it with pencil and paper – all seem to need a certain amount of programming skill. Do you know of a good outline I can read to tackling these kinds of ciphers in a traditional slow path way?
[The hints we have lined up over the next two weeks will (we hope) guide you through it. All the best, Harry]
