Code of the Month


If you want to practise, why not choose a month and see if you can crack it? And if you want to find, for example, a book cipher, why not click through a few until you find numbers?

(Warning: You may find I’ve been sneaky and used numbers for a substitution cipher. We need to be alert. Spies might be even sneakier than me.)
