Text steganography: why copying a hidden message can break it
Encryption protects the message; text steganography tries to conceal the encrypted data in ordinary writing. Hidden.Irish uses invisible characters, which editors and messaging apps may strip. The visible prose alone cannot restore a missing payload.
Use the complete text
Choose Writing Style and a real excerpt or provide text you have permission to reuse. Enter your message and key, then use Copy complete text. Selecting only the visible words with a mouse may omit invisible data.
Paste the complete result in Read and check it before sending. Also test the received copy: a successful test before transmission does not prove that a messenger preserved it. Keep any attribution required by the source licence.
Two different fallback options
Copy encrypted token gives you a visible portable token. It retains encrypted data without relying on invisible characters, but it looks like an encoded string: it is not a concealed public message.
Text image for a public post renders the real excerpt as readable text in a picture and uses the experimental image carrier. Download the picture and test the published copy. It is an image of text, not a robust plain-text channel.
When decoding fails
An incomplete payload usually means that data was omitted or changed. Ask the sender for the complete original, an image copy that passes recovery, or the portable token. A password alone cannot recover missing ciphertext.
Masking is not proven undetectable to people or AI. The choice between text, a text image and a visible token is a delivery trade-off, not a stronger encryption algorithm.
