Help with 7b

[Anonymous]

We know what cipher this is, but can’t work out how to make progress, having tried everything! Please could we have a hint or two? Thank you

All I can really say is that Jodie does her best to describe the sort of cipher used. It is very similar to Challenge 6B in spirit. But it is made harder by the way the manipulated text is read off. It is described in 7A, so I hope that will help. It might be a good idea to try to encrypt a short message using that recipe to see how it looks in practice.

Good luck, Harry
