Steganography

Did you ever want to send a secret message to someone?

Here is a fun way to do it. You can hide a secret text message in audio file.


What do you need?

- Coagula (https://www.abc.se/~re/Coagula/Coagula.html)

- Audacity (https://www.audacityteam.org/download/) or Spek (http://spek.cc/)


Coagula is an image synth and Audacity and Spek are Spectrum Analyzers.

All are freeware!


STEP-1:

- Open mspaint.exe and set the pictures size to something like: 500 x 300 Pixels;

- Your background need to be all black;

- Draw something or type some text at the TOP of picture;

- Save your picture as a BMP file.


STEP-2:

- Import your BMP file into Coagula;

- Click on a "Render image without blue/noise" button - that will render your image to .WAV file;

- Save your WAV file.


When audio is played, it will not make any sense.

It will sound similar to Dial Up modem...


STEP-3:

- Import your audio file into Audacity or Spek;

--Into Audacity, click on a little arrow next to the files name and choose Spectogram.

(i rather Audacity...)


Now you should see your hide message:


-------


=== EXTRA @ Capture the Flag ===


Listen to the sound below and follow the instructions.

The final result is a phrase with 47 characters.


If you did it, type the phrase in the comment...

Good luck!
