Sometimes, like e.g. when we need to discuss an Obsidian issue with someone, we need to provide a screenshot of a note. If it happens the note has confidential info we don’t want anyone else to read it.
@Moonbase59 has written an extremely useful piece of CSS code to easily garble text, as well as images. His code has some more features over and above kurakart’s Garble Text plug-in. You can read Matthias’s spiel about it here.
In fact, ideally you should install the plug-in in conjunction with Moonbase59’s snippet. It makes using the snippet much easier, esp. on iOS devices. Also, with the plug-in you can set a hotkey combo for the plug-in that will toggle garble/ungarble.
I have added Moonbase59’s snippet to the Github repository. In order to avoid creating too many snippet files in the repository I have added the snippet under Font, as that is what is most affected by this tool.
The link to the Github repository is given in the OP at the top of this page. On the Github page scroll down to Font.md and click on it to open, and scroll down a bit.
Enjoy.
