British surveillance agency GCHQ has launched an app teaching children to understand “basic encryption techniques”, despite its director having criticised technology firms for making more advanced tools available to their users.

Cryptoy is a free app for Android tablets, and it teaches children about four encryption techniques – shift, substitution, Vigenère and Enigma – as well as the history behind their use.
