Helpful As we move to a computing curriculum, children are learning about cryptography and how to create simple cyphers for themselves using computer programs. However the introductory stages - letter transferance is relatively difficult. The first few activities are really good but for younger children the Enigma needs more explanation - it wasn't as intuitive as some of the other material.
Cool app - but Enigma is coded wrong. Try rotor setting MEU (rotors I II II, rings in AAA position) and encode 'AAAA'. You should get GDXT but you instead get XDTT. This is because the rotor notches are not programmed correctly so the rotors don't move the way an actual Enigma does.
Confusing text says150 billion billion ways to setup (Enigma) is less than 403 million billion (Substitution)?! Reading Wikipedia might be better. Enigma machine setup needs instructions, Not clear what to do with tyre offset. Why is there a change machine option when there is only one machine listed? Need to set up again for every message.
Cryptoy I like the idea of being able to write our own messages in code, but please add a mode where we can attempt to decrypt messages the computer gives (on one of the easy ciphers), would make it a lot more fun
This is the future Great idea. Gets kids invovled and hands on with something that will be an everyday thing in the future.
Not just for children, I used it in a recent CIA research project and adults enjoyed the introduction to the art and science.
