# Emoji CAPTCHA

> A CAPTCHA implementation based on identifying emojis

This was exclusively developed to be used in Telegram, but might be used anywhere else.

## Brief Description

1. The client sends an HTTP request to the server.

2. The server returns a generated photo that has 6 emojis inside it, along with:

    - A custom header called `x-emojis` that includes the code points of the six

  emojis in the photo plus 2 random ones in hex, shuffled, splitted by ";",

  and the parts of each of them splitted by "-".

    - A custom header called `x-correct-emojis` that only includes the code points

  of the 6 emojis in the photo.

3. The client displays the photo returned by the server, along with the emojis

   provided in the `x-emojis` in a way the user can pick them.

4. The client compares the first six emojis that the user picked with `x-correct-emojis`.

This wouldn't be possible without the inspirations from the CAPTCHA system at [@PyrogramLounge](https://t.me/PyrogramLounge).
