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
set aside.

The points covered in this tutorial:

  1. The import of the visible image.
  2. The import of the image to hide.
  3. The import of the text. to hide.
  4. Saving the visible image with its hidden data.
  5. Verification of the result in Confidential Reader.

 

1. Import of the visible image

At first, we will open the folder containing the images used for this tutorial.
Click the [Open Folder …] button at the top right, to bring up the [Open Folder] dialog box.

Select the [Tuto] folder located in the installation directory and click [OK] to open it.

There is another (more traditional) way to import the visible image.
Click [File] and then [Import Visible Image …] to bring up the [Open] dialog box.

Select an image and click [open].

2. Import the image to hide

Repeat the previous steps for the image to hide.

3. Import the text to hide

 

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.

Select the image you previously saved and click [Open].

If you have followed this tutorial to the letter, you should be able to view the data you have hidden.
