A secret birthday message, hidden in plain sight
Not another ready-made greeting. Turn your own birthday wish into a small discovery: an ordinary-looking text or picture with a surprise inside.
Use the picture as a digital birthday card, or hide the location of a real gift in a text. Keep the wish short; the picture is the wrapping, not the present itself.
An ordinary note. A secret inside.
A little note for your special day. Some things are worth a closer look.
This is a public demonstration with a public key, not a private message.

- Write your birthday wish or use our editable example. No account is needed to hide it.
- Choose Text or Image and a library work, or upload a picture you have permission to use. Keep the suggested key.
- Create the result, save the key, and send the complete text or downloaded picture. Deliver the key separately, perhaps as the final clue.
Before you send it
Send the key separately and tell your recipient to open hidden.irish/read/, upload the picture or paste the complete text, and enter the key. Test the received copy: social platforms may alter images or strip invisible text data. Keep the original file or encrypted token as a fallback.
