Space Invaders

Challenge

Alien space invaders left a secret message. Luckily, you know that they used codemoji.org for the encryption.

Decrypt the message, and save the planet!!

⚾⭐📯💵🎨📢📘💪☀🌆💪🐸🎨🐦📢

Solution

• Go to https://codemoji.org/#/encrypt
• create a random message

• “share”, they give you a shortlink that resolves into “https://codemoji.org/share.html?data=….” where data is an html encoded, base64 encoded blob of json like:

  1 2 3 4

  { "message": "⚾⭐📯💵🎨📢📘💪☀🌆💪🐸🎨🐦📢", "key": "👾" }

• replace the message with the given input: “⚾⭐📯💵🎨📢📘💪☀🌆💪🐸🎨🐦📢”
• and get this url
• which decodes with the invader emoji to invad3rsmustd13
