How to Use Zero-Width Characters to Hide Secret Messages in Text (& Even Reveal Leaks)

ZERO WIDTH CHARACTER 

Unlike image or audio steganography, zero-width characters (such as zero-width non-joiners and zero-width spaces) can be embedded in text without being visible, making them useful for covert communication and identifying information leaks. The article explores practical applications, including using these characters for secret messaging, canary traps to identify leaks, and modifying URLs to disrupt their function. It also provides steps to create zero-width messages, use encryption for added security, and tools to detect or remove hidden characters.
