SilentEye: Hide one file inside another

SilentEye is an application written in Qt that will help us to make use of the Steganography and hide images and audio within another file.

According to Wikipedia:

La steganography It is the discipline in which techniques are studied and applied that allow the concealment of messages or objects, within others, called carriers, so that their existence is not perceived. It is a mixture of arts and techniques that are combined to form the practice of hiding and sending sensitive information in a carrier that can go unnoticed ...

… The origin of this word derives from the composition of the Greek words steganos, which means covered or hidden, and graphos, which means writing.

Be careful with this tool, because in many countries using this technique is PROHIBITED. Its use is very simple.

1- We get off the .deb from this url. There is also for Mac y Windows.

2- We install the following dependencies:

$ sudo aptitude install libqca2 libqt4-opengl libqtmultimediakit1

3- We install the package we downloaded:

$ sudo dpkg -i Downloads/silenteye-0.4.0-i386.deb

4- Let's go to Menu »Applications» Accessories »SilentEye and we should get something like this:

5- We drag an image.

6- We press the button Encode.

There we can choose several options. We can hide a message or a file and even if we want to, encrypt it. As we can Hide a file or message in an image, we can do the reverse process.

The only bad thing that I see with the application is that the images are saved with an extension . BMP and the audio files like .WAV.

    Hello, it is not possible to hide it in other types of files such as mp3 or avi and that they continue to work. I understand that with cat the same is achieved in an image but not in an audio or video file.
