Text watermark & Steganography toolkit - version 1.0.0

This project is a hexadecimal zero-width character text steganography kit written in javascript (runs in browser). It can hide totally invisible messages or watermarks within normal text. Works perfectly with discord, some email clients and various other chatrooms/apps. As it uses hexadecimal you can hide fairly long invisible messages in any text. It does not require an internet connection to work as it is fully local, so your data is not intercepted anywhere until you send/publish your generated message.

To use: Download, extract and open index.html.

There is also a live version if you just want to play with it. https://rabian.io/text_watermark/

Abilities:

• Encode and decode invisible encrypted messages in plain sight, via discord, email and other types of text communcation.
• Works with just HTML, CSS and JS, easy to use.
• Watermark content with invisible characters to prevent theft and plagiarism.
• Seed text with zero width characters to avoid AI detectors, plagiarism checkers and deter editing and rewriters.
• Has potential to poison AI training data.
• Can spam text with spaces to potetially bypass spam email filters. Or strip the spaces.
• Add invisible watermarks whenever somebody copy pastes anything from your website.
• Can be used on some badly coded services to have a totally invisible name or description.
• Generate meta and h1 tags for your website with an invisible code.
• Has an included server version that uses cookies if you wish to mirror this.
• View and strip invisible characters.
• No dependencies, you just need a browser.
• Has high potential for mischief.

Problems:

• Some services filter out invisible characters. Use the inluded tester at the bottom of the various pages to see how the characters interact with a service before use.
• The encryption is difficult but not impossible to crack. The key code has 355687430000000 possible combinations, but a well designed cracker could break this (if anybody is up for the challenge it would be a fun project).
• As this project uses a lot more invisible characters than most similar projects, it's much more likly that one of the characters will cause problems so it's potentially more unstable. On the flipside this makes it hard to crack and it can encode much more data in a shorter message.

Contributions & education:

• If anybody would like to add to or improve this toolkit feel free.
• Also feel free to make content on youtube, or educational platforms if you find this interesting.
• If the author of the whitespace programming language ever see's this, feel free to make the nospace programming language. An esoteric language based on this would be pretty funny.

Extra content:

• I plan to include an extra weird character section when I get round to it and maybe an advanced version of Zalgo. I found many more zero width characters too, some of them can be very problematic. I will eventually add them all so other people can be made aware of them. I am currently working on a version with better encryption as I have discovered extra working characters.
