[[wp>Steganography]] is a method of concealing hidden messages inside objects. In the context of computing, it may be a message encoded into an image, audio file or another type of media.

Some files we found in [[dead_drops:el_paso_drop|El Paso drop]] contain hidden information encoded with ''steghide'' tool.

==== Getting steghide ====
  * Windows/Linux: [[https://steghide.sourceforge.net/]]
  * MacOS: [[http://packages.macports.org/steghide/]] or (if you use MacPorts) ''port install steghide''

==== Decoding information from images ====

Example how to decode information from one of El Paso files.

  - Download {{:elpaso:maria_1.jpg?linkonly|}}
  - Decode: ''./steghide extract -sf Maria_1.jpg''
  - When prompted for passcode, press enter
  - File ''code.txt'' should be created

Your result should look like:
