### A CAPTCHA implementation based on identifying emojis
This was exclusively developed to be used in Telegram, but might be used
anywhere else.

Git](https://git.zeldon.ru/zeldon/emoji-captcha-api)
## 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`.
