FontU!

Simple Python script to:

1. shuffle characters of the text content of your HTML,
2. accordingly (in reverse order) shuffle symbols in the font,
3. add the font into your HTML,
4. congratz, text contents of your HTML are machine unreadable, yet human can read it just fine.

Problems

Text encrypted by FontU will not be readable by screen readers. We plan to investigate and fix this problem. Maybe we could manipulate the vocal files accordingly? If you have experience with screen readers, please let us know. We deeply appreciate your feedback and ideas.

Example commands

For simple one-step encoding, run do subcommand and spefcify input HTML with an input font: python main.py do -i in_html/gajdosik-org_sample.html -f in_fonts/Roboto/Roboto-VariableFont_wdth,wght.ttf

Or alternatively first create a shuffled font and coresponding keymap holding about exact shuffle order: python main.py wys -f in_fonts/Roboto/Roboto-VariableFont_wdth,wght.ttf

Then call wtg to use the keymap to encode HTML file and add decoding font to it automatically: python main.py wtg -i in_html/gajdosik-org_sample.html -k private/fontu.json
