Students in the Advanced Cyber Security Concepts course had to perform a number of activities that displayed their ability to master the cryptography domain.  This included performing basic stenography encryption.  The graduate student selected Steghide application to perform this task.  In the figure below you can see the student’s encrypted photo and the command line commands used to decrypt it.  See Steghide documentation and steps at http://steghide.sourceforge.net/documentation.php
