We promise we didn’t fall asleep on the keyboard. The above emojis aren’t nonsense — they’re a cipher, a message scrambled using a code. When you decipher them using Mozilla’s new Codemoji game, they read: "Happy World Emoji Day."
Though modern encryption is much stronger and more secure, ciphers are at the root of how encryption works. We use encryption every day to keep us safe online. Banks use it to safeguard credit card data and your banking information. Hospitals use it to protect medical records.
Encryption is one of the most important tools we have for building a more safe, secure Internet.
But many people don’t understand how encryption works. At the root of encryption are ciphers, the method that determines how an encrypted message is scrambled. So we built Codemoji, a Web-based educational game that teaches everyday Internet users about ciphers, the building blocks of encryption.
Keep in mind: Codemoji is intended as a fun learning tool, not a platform for sharing personal information or communicating securely. That said, it’s a really fun way to learn about ciphers and encryption.
We can’t wait to see what you make this #WorldEmojiDay. Thanks for all that you do,
