Cryptoy: Free GCHQ developed Android app

[LosOjos]

This fun and educational app teaches you about the mysterious world of cryptography. It helps you to understand ciphers and keys, and enables you to create encrypted messages that you can share with your friends.

 

You'll learn about four encryption techniques:

 

- Shift

- Substitution

- Vigenère

- Enigma

 

You'll have a fun and interactive way of building your own messages using each technique, as well as learning the history behind their use.

 

Once you've created a message, you can share it with your friends and see if they can decrypt it... It's up to you how much help of information you give them!

 

Cryptoy is brought to you by STEM students sponsored by GCHQ, the UK intelligence agency responsible for providing Signals Intelligence (SIGINT) to Her Majesty's Government. We are also the UK's National Technical Authority for Information Assurance, and provide guidance on the use of technology and encryption.
