History

Codemoji was part of the early 2016 Mozilla Foundation Encrypt campaign. Encrypt was a series of videos—along with Codemoji—that explored the importance of encryption. It was ideated and developed by the TODO design studio.

What was Codemoji?

Codemoji was a web-based platform that allowed people to send a short message to friends that was then ciphered into emojis. Once the message was sent, the sender would send the receiver a small hint in order for them to decode the emoji scrambled message. The project was intended to demonstrate in a simple and fun way how encryption works on the web.
