The basics of Confidential
In this first tutorial, you will quickly learn how to hide an image and a text.
We will use the common ID key, which means that any person in possession of
Confidential Reader will be able to decrypt the hidden data.
The common key connects all Confidential users. Never use this key if your data
is to remain confidential.
The next tutorial (planned for in a few days) will address some functions deliberately
The points covered in this tutorial:
- The import of the visible image.
- The import of the image to hide.
- The import of the text. to hide.
- Saving the visible image with its hidden data.
- Verification of the result in Confidential Reader.

4. Saving the visible image with its hidden data
In the top part, choose the folder where the image will be saved.
In the drop-down box, choose a contact. In this tutorial, we will choose [VISIBLE BY ALL READER].
We will see in the next tutorial, how to create a new contact.
5. Verification of the result in Confidential Reader.
Click the [Test with Confidential Reader …] button to open the Confidential Reader.
In Confidential Reader, click [File] and then [Open image] to bring up the [Open] dialog box.
