Hi Harry,
It’s good to be back doing the Cipher Challenge (although my username is different from last year so you probably won’t recognise me). Hope you and the elves are well.
I was wondering what the policy on [EEEDIT, Harry: using code on other] websites is? Is any use of a website like that chesting, even if it’s just for frequency analysis or checking a Caesar shift? Also, if you write a computer program yourself, can you use that? I’ve never been taught how to make cipher solving programs but I know others have and I would definitely teach myself if you thought it would be useful for the cipher challenge.
Thank you
