emojito-py 0.2.0

Encode text into emojis using Unicode steganography

🍹 emojito

emojis with a hidden agenda.

A Python library and CLI tool that lets you secretly encode text into ordinary emojis using Unicode steganography. Hide messages in plain sight and share them anywhere emojis are supported.

Inspired by Paul Butler's article "Smuggling Arbitrary Data Through an Emoji".

Installation

Install from PyPI:

pip install emojito-py

Or install the latest development version directly from GitHub:

pip install git+https://github.com/matijaoe/emojito.git@main#egg=emojito-py

on a mac?

On macOS, pipx is recommended for CLI tools:

# Install pipx if you don't have it
brew install pipx
pipx ensurepath

# Install from PyPI (recommended)
pipx install emojito-py

# OR install from GitHub (development version)
pipx install git+https://github.com/matijaoe/emojito.git@main#egg=emojito-py

This installs the package in an isolated environment while making the CLI commands globally available.
