I recently made this as a component in a larger project https://gist.github.com/MatrixManAtYrService/7fc7fb05474d971...

The idea is that even if you can't see the full data for some reason (space constraints, in my case), different values will appear styled differently even if the non-hidden characters don't differ.

I'm not sure how easy/hard vscode makes this, bit it might be fun to use a hash of the secret (salted by that character's index) to determine the back/foreground colors of the *'s

That way even though you can't see the secret, you can tell that it has changed. Also you're in a position to notice if two hidden secrets are the same (this might clue the user into a mistake, like if they didn't actually copy what they think they copied and are instead pasting the previous thing.
