When enabled, prepends an invisible zero-width signature to the output. This allows inØsight to automatically detect hidden messages across web pages, identify the base and cipher, and show the on-screen decode button.
How ZWUS Works
ZWUS (Zero Width Unicode Standard) hides messages in plain sight by converting text into completely invisible Unicode characters:
- Convert: Translates each character (or encrypted data) into numeric values.
- Encode: Maps those numbers into a custom alphabet of zero-width, invisible characters separated by an invisible delimiter.
The resulting text looks completely empty or hidden between ordinary letters. Decoding simply reads the invisible characters and reconstructs the original text.
For details regarding picking the optimal standard/base, see docs/zwus.md.
For cipher details, see docs/cipher.md.
Use ZWUS in Your Own Projects
The encoder/decoder is available as a standalone package for multiple languages:
- JavaScript/TypeScript: zwus on npm
- Rust: zwus on crates.io
Note
Encoding works with all Unicode characters in existence (
U+0000toU+10FFFF), including every language script, emoji, and symbol.
