Steganographr

Hide text in plain sight using invisible zero-width characters. Its digital steganography made simple. Inspired by Zach Aysan.

You can use Steganographr on its web page, or download the source from this repo.

How it works

Steganographr works by converting your private message into binary data, and then converting that binary data into zero-width characters (which can then be hidden in your public message).

These characters are used:

  • WORD JOINER (U+2060)
  • ZERO WIDTH SPACE (U+200B)
  • ZERO WIDTH NON-JOINER (U+200C)
