Teen Crypto App

Lola wants a new app that automatically converts real words as typed into a phone or computer into a teen’s crypto language that she and her mates currently use to pass notes around.

I think the crypto language is used so that their notes can’t be read accidentally by the boys that are the subject of the notes.

The app would intercept the commands sent from the keyboard or touchscreen and display the crypto language in whatever messenger service they are using, which seems to be Instagram at the moment. That is, English would never be shown on the screen on the sender’s device.

It would also be received and read in crypto-babble.

Interestingly just about all encryption currently on the net encrypts a message at one end and decrypts it at the other, and hence there is a requirement for shared information (e.g. a key) between the two devices which inherently creates a security hole.

This new idea only encrypts at the sender end and there is no need to decrypt at the other end since the recipients have all memorised the decryption algorithm.
