★★★★★
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.
★★★★★
Fascinating! Very interesting content and very creative presentation!
★★★★★
Brilliant Brilliant, still needs work, but a brilliant app all the same please add Enigma instructions and in-app sending for codes, and make a Facebook page for it!!!
★★★★★
Great example Easily describes and shows in pictures how old cryptography worked although i would like to see more of those and better visualisation for ceasars ring, and some challenges to crack crypted text
★★☆☆☆
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.
★★☆☆☆
Please we need more spies So GCHQ are looking for the next generation of people to hack computer systems and steal information, yay.
